Sennheiser Consumer Audio HD 4.40 Around Ear Bluetooth Wireless Headphones - Black

I bought these Sennheiser Bluetooth headphones over a year ago and I still think that they are the perfect pair of headphones. They are ideal for anyone out there who needs a great pair of headphones. From a casual user listening to music, to a professional producer working in a studio; these headphones will check off any qualifications you are looking for in a pair of headphones. One of my favorite qualities about these headphones is that they are durable. When I’m looking for products to purchase, I want them to last a long time even if they are put through tough situations. These headphones have traveled with me anywhere I go. They’ve been thrown on my bed after a long day at work, compacted into my backpack when I’m going to class, and the continue to work like a charm. Compared to other headphones on the market, you can really tell that Sennheiser puts a lot of effort into creating a high-quality product that will last a long time. The headband on these headphones is extremely durable yet has slight bend to them. The ear pads have a great cushion to them that fits right around my ears. I could wear these headphones for hours and still be comfortable. Another great thing about these headphones is that they fold up to minimize space when packing them away in a bag. It’s a great plus to have in a pair of headphones. I haven’t even mentioned that they’re wireless! Having Bluetooth built into these headphones only adds to the practicality of them. I’ve never had a problem connecting them to my devices and they always produce great audio. They also don’t force you to use the Bluetooth. The headphones come with an aux cord that can be put on and removed easily. It works great for devices that do not have Bluetooth. The battery on these headphones also lasts a lot longer than I originally thought that they would. Sometimes I could go a whole week without charging them and it doesn’t take any time at all for them to charge. They are a very practical pair of headphones. Overall, I think that these Sennheiser headphones are great. As an avid music listener, I highly recommend them to anyone looking for a great pair of headphones at a very reasonable price. Comparing these to other brands of headphones that may cost a lot more, they give you great bang for your buck.

Summary: The Sennheiser HD 4.40BT is a relatively affordable wireless headset by a well-known brand. It generates excellent audio quality, has incredible battery life and very comfortable to use for long hours. The headset is light, made from quality materials, the Bluetooth connection works great with no disturbances, and you can operate it using NFC as well. Before reviewing this headset I’ve been using it for more than a year, and I can say that it took me time to appreciate the HD 4.40BT's audio quality. The sound experience it offers is worth every penny. It generates the right sound for every type of audio content I've been listening to, whether it's music (from all genres), lectures and audio books or phone calls. The bases are sharp but not explosive. It can reach a high-volume level, but there's no distortion in the sound. And when listening to audio using this headset, especially to music, you enjoy from a full sound experience. At the beginning of my video review, I placed the microphone next to the headset, so you'll be able to hear how it sounds. I do that because I'm asked by my viewers, who wants to know as much as possible on the products I review. But let's be honest, it can hardly reflect the audio quality unless you'll be using the headset yourself. And if you will try this headset, then you'll probably won't want to take it off. Though this model doesn't offer ANC (Active Noise Cancellation), you will be quite isolated from your environment. If you don't listen to audio then everything around you will be much quieter, while if you listen to music, at a certain level you won't hear anything from your surroundings. According to Sennheiser, the battery should last up to 25 hours, but assuming you don't raise the volume level to the maximum level, the battery will last much more than that. I always kept asking myself when the last time was that I charged the battery because I kept using it for such a long time between each charging. I would say that if you're using normal volume level, the battery can reach even 50 hours. As for how comfortable this headset is, you’ll be glad to know this is one of the most convenient headsets I've ever worn. The headband & the earphones are padded well (but not too much), the earphones have a range of movement that is adaptive to the shape of your head, and the headband is elastic and extends to the right size of your head. The HD 4.40BT is made from quality materials. And after more than a year of intensive use, the headset still looks & feels great. During this time, it took some bumps & scratches while, but thanks to the type of materials, they are almost unnoticeable, and allows the headset to withstand much worse damages that could leave a mark. This is one of the main differences compared to a low-budget headset since it isn't made from cheap plastic or includes a simple cushion to soften the earphones and headband. I noticed that sometimes when I minimize the arc, the arc isn't fully minimized from both sides, and the pops a bit outside. Since the quality of materials and build quality are great, and I was very careful when using this headset, I'm not sure if the headset is meant to be like that (since it is also foldable), or it just happened over time – but this isn’t a deal breaker for me. The Bluetooth connection works great, and I didn't encounter any disturbances or disconnections whatsoever. There’s a designated app for this headset named “Sennheiser CapTune”, that I almost didn't use. When I did try it, I almost didn't have what to play with it, since I consume my content mostly from YouTube & Audible, which aren’t supported by this app. The pouch that comes with the package is from good quality and is useful for cleaning the earphones. It is common to offer such pouch with headsets, and yet, I wish Sennheiser would give instead (or in addition) a hard case to store & carry this headset. Overall, If you consider purchasing this headset, then I believe it would be a great purchase. Please note I attached to this review screenshots + a video review I made about my experience with this controller. The pros: - Excellent Audio quality - Good isolation from the outside - Battery life - Comfortability - Quality of materials - No disturbances in the wireless connection - The built-in microphone enhances your hearing The cons: - The App isn't compatible with YouTube / Audible - The arc can't be minimized perfectly - I wish it came with a hard case **** FAQ : **** If you have any, please do ask and I will do my best to answer them.

I’m not exactly an audiophile; I am a 30 year-old professional singer who spends a lot of time listening to music (predominantly historically informed Baroque, hip-hop, and prog metal), and recently I’ve started trying to improve my listening experiences with higher quality equipment, on a typical musician’s limited budget. When I bought the Audioengine A2 speakers for my computer a couple years ago, *everything* instantly sounded better, more detailed, richer; music that I already knew well came to life in new ways. So, that experience definitely got me hooked on how good equipment can make music sound better, and I was hoping to replicate that magic when I bought these Sennheiser 4.40bt headphones. I prefer Bluetooth headphones because I usually wear my headphones when I’m out and about in the city or on the subway, and I just can’t be bothered with a cord – if there is a sacrifice in the audio quality versus corded headphones these days, I think it’s too small for me to really discern, and the freedom of having no cord is fantastic. On the other hand, it does mean you’re going to pay more for something decent: I did extensive research before settling on this model (on sale for $100), and I also considered the 4.50btc (same cans but with ANC for $150), the PXC 550 (Sennheiser’s top-of-the-line Bluetooth ANC cans for $300), the Bose Quietcomfort 35 (which everybody seems to agree are the best around, $350), and the many, many over-ear headphones by weird no-name Chinese companies that you can find on Amazon in the $60-70 range, all of which have hundreds of suspicious 5-star reviews, and many of which also seem to have ANC. (If you google for a real review, not on Amazon, of any of these popular headphones, you will get the lowdown on what they're really like.) The temptation to go for something in this category was strong because I just didn’t have $300 to drop on headphones, but in the end I am very glad that I swallowed my pride and got a more entry-level product by a reputable company. After some initial disappointment and some software tweaking and getting to know them, I’m very happy with the Sennheiser 4.40bt. My first listening experience was a letdown. I tried them on, listened to representative favorite albums from several genres, and came away with the same complaint in each. I’m not well equipped to provide verbal descriptions of my complaints, but I would say that everything sounded tinny, two-dimensional, and, surprisingly, not even really loud enough. I would have to crank the volume up all the way to the top to be able to listen to anything classical in the subway, and I worried that maybe I’d made a mistake not going for the noise-canceling model. Sennheiser suggests that you use their proprietary equalizer app, Captune, with these headphones, so I decided to give that a shot, and it certainly did improve my experience. The presets for classical and rock alone pretty much made everything sound completely different (i.e. better) regardless of genre. But Captune is an annoying, finicky app – I’m a Tidal subscriber and I was excited that Captune allegedly plays nice with Tidal, but even this turned out to be a disappointment: you end up having to navigate your Tidal library through the Captune interface, which is unintuitive and doesn’t allow you to access your offline albums. And if there’s a way that you can make your Captune EQ settings apply to all the sound on your phone instead of just what you play through the Captune player app, I wasn’t able to figure it out. This led me to find a third-party equalizer app, of which there are many. I paid $1.99 for an app called Equalizer FX Pro on the Google Play store, and this provided me with all the benefits I’d experienced with Captune, but also with the ability to use the equalizer when you’re using whatever app to play music (in my case Tidal), plus a loudness enhancer which has solved my aforementioned “not loud enough” problem. Basically, with the addition of this app, the 4.40bt have become a set of headphones that I feel very good about having paid $100 for. Certainly, I wish that no additional software were necessary for that to be the case, but at this point I’ll take it. Other things: battery life of the headphones is great, they last much longer than the cheap Archeer over-ear Bluetooth cans I was replacing. Pairing etc. is easy. I do have a complaint about the comfort of wearing them: the band doesn’t feel great on the top of my head, perhaps because it isn’t padded thickly enough. This has become less of an issue as I’ve played around with different ways to position that band, but they could be more comfortable. The pads over the ears are great, no complaint with how those feel. Pros: at $100, great value for audiophile quality (some work with an equalizer required) that most of the premium Bluetooth headphones will charge $300+ for. Block out noise pretty well without noise canceling. Comfortable fit over the ears. Conservative but attractive style. Nice build quality. Don’t turn on by accident in my bag and drain the battery like the ones I used to use. Cons: I found that in order to get great sound you have to use an equalizer, which adds an extra step to the listening experience but is worth it. Band a little uncomfortable on the top of my head. Four stars. Are my standards too high? Debatable. Obviously all the cheapo headphones in the $60-70 range do not deserve to have so many five star ratings, but they get them either because they’re fake reviews or because people who buy those headphones end up being pleasantly surprised by how much bang they got for their buck. Fair enough. Maybe I’m a little disappointed that I didn’t get something perfect when I spent my hard-earned $100, and maybe that is an unrealistic expectation. Maybe in a few years I’ll be in a place where I can drop $300 and get “the best.” If and when that happens, I would consider Sennheiser as a valid rival to Bose, but I would like to try them out first… hopefully by then they will have sorted out their equalizer problems (meaning either you won’t need an equalizer to make things sound good, or the Captune will become some effortless thing that automatically makes them sound like they should regardless of what media player you’re using).

I am a bit of an audiophile and I never thought I'd get into the bluetooth craze, but I actually love it! Much more convenient than wired headphones and it's more aesthetically pleasing. Bluetooth headphones have come a long way over the year and as always Sennheiser sets the bar. Sound quality: Nice tight base, clear mids with clear treble that is still smooth and fatigue free. Even though I hold high expectations for Sennheiser these sound much better than I thought they would. Build quality - It's plastic, but it feels like a nice smooth quality plastic. Not cheap by anyways and the tolerance points seem well planned and these shouldn't ever break unless you purposely try to damage them. Comfort - Like most headphones the first time you put them on there is a bit of a clamp, but it gets loose and comfortable in no time. The ear pads aren't "over ear" or "around ear" by any means - I have average size ears and these are on ear headphones, but they are very comfortable I am very satisfied with these headphones. They kill the more expensive bose and beats headphones in sound quality and I tried the sony xb series and those were too base heavy and sounded lower quality overall. I haven't tried the sony flagship, but the touch feature wouldn't work well for me as I tend to use headphones in bed a lot and with those if a bed sheet or pillow or something rubs against the side it will play/pause/skip/etc. I'm not a fan of active noise canceling as it makes me feel dizzy and in general I feel like closed cans block out enough sound without active noise canceling. So with these you get pay for pure audio quality and even though they aren't hyped as much as bose and beats through social vanity, anybody who knows audio can agree that these sound much better. These are easily the best BT headphones to buy right now and I doubt anything will de-throne them anytime soon. The only thing I don't like is that there is a beep every time you change the volume and you can crank up the volume on the headphones and then turn turn volume sync off in bluetooth settings to control the volume on your phone without any beeps, but when you turn the headphones off and then turn them on again later, you have to crank up the volume on the headphones again as it goes beep beep beep beep and that's pretty annoying.

The Short: Affordable, dependable, over-ear bluetooth headphones with high usability, rich sound with good separation from trusted brand in audio. I run a professional video and photography production company, and use these headphones on a daily basis for both editing and entertainment. If you are considering this pair of headphones, odds are you are simply looking for a pair of wireless bluetooth headphones with the best quality sound that can hold up to casual daily use. Congratulations, you’ve found it. The tech specs are readily found on Amazon and Google, so I won’t get into the technical side in this review. Instead, I will talk about (1) build quality + durability, (2) reliability, (3) sound quality, (4) usability, (5) comfort, and (6) transportability. 1. Build Quality + Durability The headphones are made with hard plastic all around; there are no visible metal parts on the headphones. They are lightweight, but overall construction feels solid and the plastic feels and looks like high-quality plastic and not cheap and toy-like. I travel a lot for my work — spending my days between editing out of coffee shops to flying across the country on production. The headphones either travel with me around my neck, folded in my padded equipment bag, or folded into my daily commuter backpack without any hard case around it. In all instances, over the last 2 months of daily use, I have never had any issues with the headphones nor have I had to worry about them not holding up to travel. So far so good! 2. Reliability One of the most important factors for me in choosing a bluetooth wireless headphone was the reliability of the connection. I grade this on (a) the connection strength of the headphones and (b) the ability of the headphones to connect with my devices every time. These headphones have performed with perfect marks across the board in both categories. I’m an Apple user, and use these headphones daily between my iMac desktop, MacBook Air laptop, and my iPhone X. The bluetooth connection is always solid, and the sound coming through is clear with no audible lag, distortion, nor interference. If using with just one device, the headphones will pair quickly and automatically, which is nice. Switching between each device has been super easy for me — just hold the power button down when turning the headphones on to place the headphones into pairing mode, then select the headphones from your device’s bluetooth pairing menu. 3. Sound Quality These have great sound clarity, rich midtones, controlled highs, full base (but not overwhelming), and remarkable sound separation. The headphones may be used both wirelessly, or with the wire that comes with the headphones. As with all wireless/bluetooth headphones, the audio quality is always better if directly connected to the device. However, these headphones do a truly fantastic job of preserving audio quality in wireless bluetooth mode. I would say there is a negligible difference in sound quality between wired and wireless, which is really only noticeable if you are comparing it side-by-side. I was a long-time user of the Beyerdynamic DT 770 PRO 80 Ohm wired studio monitoring headphones, which are still my headphones of choice when monitoring sound on film productions due to its flatter profile which allows me to hear frequencies on a or even spectrum. On the contrary, the Sennheiser HD 4.40’s noticeably richer and more responsive tones and fuller base makes it more enjoyable to listen to, despite being less than HALF the price. If you want a pair of headphones that enable you to ENJOY your sound and not just monitor it, I definitely recommend these headphones. Even in their wireless mode, these headphones have allowed me to hear and feel MORE from old music I’ve heard many times before. 4. Usability I spend a lot fo my time between my desktop, laptop, and cell phone for work. The pairing and switching process is super easy., and I have never had any issues with these headphones with any of my devices. I have used these for a full day of flying and traveling, and did not run into any issues with battery life, which Sennheiser boasts as having up to 25 hours of battery life while in wireless mode. The controls on the right ear cup of the headphones are easy to access for me, though toggling them produces an audible “beep” from the headphones while in wireless mode. Many of complained about how annoying this beep is, but I personally don’t mind having audible feedback to my input. Using the headphones in wired mode disables the functionality of the buttons on the right ear cup, thereby eliminating the “beep.” 5. Comfort The ear cups that come with the headphones are made of a supportive but super soft memory-foam type material, covered by a smooth and high-quality feeling stitched pleather material. Many of complained that the ear cups are too small to fit over their ears, and should therefore be considered on-ear headphones, though I have never had that problem myself based on my ear-size. My ONLY complaint is that the padding on the bottom of the headband where the band touches the head does not have very much padding, which can create some discomfort when wearing over a long period of time. I have the headphones at their max extension to avoid tension from the headband hurting the top of my head. The headphones stay on my head very well and does not slip around despite being on the widest setting. 6. Transportability To transport, the headphone’s ear cups fold INTO itself, though the ear cups do not fold flat. As a result, they produce a taller profile vs. headphones that fold flat. When I travel, the headphones are either around my neck for ease of access, or folded and placed into my padded equipment case, equipment backpack, or simply tossed into my daily commuter backpack. They really are a fantastic pair of wireless bluetooth headphones for the commuter and daily user who wants to enjoy their sound. -------------------------------- Conclusion: For their price range ($70 at the time of this review), they are really hard to beat. If you are looking for a pair of headphones for entertainment and not professional/commercial use, it's hard to go wrong with the Sennheiser HD 4.40. Great for the commuter and daily user. Would buy again.

I've used a lot of Sennheiser headphones over the last decade or so, starting with the HD202's and 201's, and eventually progressing through the HD280's, HD 380's, HD 598's, HD 598c's, and HD 6xx. Having extensively used all these more or less "professional grade" studio headphones for as long as I have, has given me a very spoiled, and almost stubborn ear for sound quality, and have for years scoffed at the idea of blutooth headphones sounding anywhere near a quality that even resembled decent. Until I actually tried some, and they weren't actually that bad. Until they stopped working. And those were my 50$ JBLs (shame cause I generally like JBL speakers, guess headphones aren't their game). I decided I would go a bit more, and go with my trusty old Sennheiser for my next pair of bluthooth cans. And boy oh boy was that the original decision that I should have made. These things sound incredible. Honestly, they are on par with wired headphones by Sennheiser that cost more money, such as the HD280's. I wouldn't go so far as saying they are on par with like the 380's or 598c's or anything but damn they are up there. But the quality is there, the tight responsive bass is there, it's all there. And you can run these things wireless or wired, which I have yet to try wired, but I can imagine that it might even sound better with the right source. Honestly if I had both headphones sitting on a desk in front of me, the HD280's or these HD 4.40 BT's (wireless or wired) I would definitely go for the HD 4.40's every time. That's actually a really good juxtaposition for another point that I missed, and that's that these headphones are extremely comfortable. The HD280's are particularly notorious for their clamping grip that squeezes the life out of your head after hours of use, and that is not an issue with the BT 4.40's. I got these specifically for use at work (warehouse/stocking) and wear these bad boys for hours straight, and cumulatively probably like 5-6 hours in any given shift and it's like nothing. Like that 6 hours wearing them doesn't change anything, I could do it again, and again after that. Sometimes I straight up forget I have them on, which was a sensation that I had only experienced from the HD 598 (open back) and Hd 6xx (also open back). Also I prefer my headphones to be more headphone and less gimmick, so I never go for noise cancelling models. If noise cancellation is that important to you then go ahead I guess, but I always find the mild sound dampening of over ear headphones to be enough for me. These don't really knock any headphones out of the park in terms of passive noise suppression, they are pretty standard, and on par with any other closed back headphone really. The HD280's are superb at passive noise suppression though by my standards, and these headphones are not quite as suppressing as those, they are more on par with like the hd380's or 598c's in terms of their suppression.

Despite many reviews, those headphones are extremely comfortable for my ears, I like controls, ease of connectivity and battery life. What I found really mediocre is a sound. Bass is ok, little plush but ok, I'm not looking to over-charged "Beats" sound. A general sound picture is not vibrant, lacks "wow" effect and I found highs are kinda hissing. I'm going to play with 4.40 for few more days, try different inputs and EQ settings but am pretty certain I will return headphones. I think it's a very good headphone for this money ($115 on Amazon) with great comfort and functionality but I personally need much better sound. I am by no means a headphones expert and have tried only those and Bose QC, which are better but also lacks sound clarity for my taste and I don't need active noise cancellation (actually this feature only distorts sound in my opinion). ** UPDATE ** Unfortunately, I had to return them. What I found after a testing with different setups (wired/wireless) and sound sources (Spotify, Tidal HIFI, local lossless files) — the problem was with a wireless connection. I loved the sound of 4.40 when they are wired to my S8+ and would give a solid 8.5 out of 10 (and 9.9 would be wired Detroit Shinola studio headphones with an expensive amplifier and HiRes audio source). When they are connected via BT — it's just completely different headphones — muffed mids, distorted highs and who cares about a bass than?! I don't know what was the reason - may be my item was defective or they are not working right with Android phone (and I forgot to test with iphone) or something else. I'd be happy to keep them if a wirless sound would be identical to a wired.

UPDATE 1 Year Later: So everything in my original review stands. Great battery life, like really good. I still wish there was an audible indication on how much battery life is remaining but I've yet to run into a problem with these. Sometimes I'll go weeks between uses and they'll still be fine. The biggest improvement, however, came after I upgraded the earcups. The OEM earcups were just too uncomfortable for my big head ( 7 3/4). However, I purchased a pair of Brainwavz HM 5 Velour ear cups for $20 & it upgraded the comfort level immensely. Now, rather than being on-ear headphones with the OEM pads, they are truly over the ear because the HM 5s have a much wider opening. The downside is that this affects the sound signature a bit. You lose some bass, so bassheads be warned. But, in my opinion, the gain in comfort outweighs the loss in sound quality. I will note, however, that these are $100 headphones & BT at that so they were *never* meant to be audiophile grade headphones. So folks looking at these specific headphones should set their expectations appropriately. I use my Beyer DT 880s or Senn 650 for more critical listening. I bought these specifically for portability -- when I am in a coffee shop writing for a few hours & just need something serviceable. These fit that bill. If you're expecting these to sound like Audeze LCD-4s, then you're going to be really disappointed. ---- I've had these for about a week now. I love them, with a caveat for those folks with larger heads. First, sound: I'm not an audiophile but have several pairs of midrange headphones. My favorites are Beyerdynamic 880s for reference. For wireless Bluetooth headphones, these things rock. I would compare them with my Senn HD 598s. They just sound right to me. I listen to a lot of punk and these seem great for that genre. These aren't bass-heavy so if that's your cup of tea, you may want to look elsewhere. Fit: I have a large head. 7 3/4 big. The clamping force on these is a bit painful. My 880s are super comfortable as are the 598s. I think it's due to the fact that although these are supposed to be over the ear, they actually sit on my ears. Sometimes I'll maneuver them a bit to sort of fit my ears within the cups, but that does little to allieviate the pain. It's not ridiculous like the Beyerdynamic DT 1330s but it gets uncomfortable after an hour or so. On the positive side, a quick break/adjustment and I'm good to go. The earcups are extremely cushy. These aren't noise canceling but due to the size of the earcups and how they sit on your head, they block out a fair amount of noise. I suspect they will be great for commutes, on planes, and etc. I normally use them in a coffee shop that often plays ridiculously loud music and I don't have any problems. Bluetooth: no connectivity problems with my iPhone, PC, or Mac. I can switch between them with little effort. Battery life: seems great. Haven't had to charge them yet but they've held up for several long writing sessions. Portability: these fold up quite compactly. They come with a cloth bag that I don't use. I just shove them into my bag and forget them. If you're concerned about breakage, you'll prolly have to buy an hardcase from somewhere else. Extras: there's a micro USB charging cable as well as a 3.5mm connector. Price: you really can't beat the $150 price tag--at the time of review obvi. I looked at Sony MDR-1000x & Bose QC 35 as well. With the durability questions surrounding the Sony and the price tag of the QC 35, I figured ANC isn't a feature I *need* and certainly not worth (for me) the additional $200 for the Bose. Your calculus will obvi be different. For my money, I couldn't be happier with the purchase. I normally just used my 598s as my everyday headphones but, since they don't fold and have that wire, I wanted wireless. I'm glad I bought these.

جيدة جدا و بتعد مدة تشغيل كتير بعد بالتلات تيام ما اشحنهاش. منتج و جودة المانية ممتازة. بس فيه عيب لازم اما تيجي تشغلها اول مرة عشان يشوفها الموبايل او اللابتوب، لازم و انت بتغط ع الزرار بتاع الباور تفضل ضاغط لمدة ثواني متواصل لغاية ما يقلب من الازرق الي الاحمر و يفضل يقلب بين اللونين منتظرا انك تكونيكت عليه من الموبايل او اللابتوب. ساعتها الموبايل او اللايتوب ح يشوفها و بعدين تعملها pair. وده مش مكتوب في الكتالوج. بس هيا جودتها صوت نقي عالي الجودة للغاية. و خامتها جيدة للغاية وده بعد تجربة اكتر من سنة. سينهيزر ماركة الماني معروفة.

Actually this Headset / Headphone does come with some cons but these surely even compete against some top of the end wireless ANC Headphones like Bose QC35. Also 4.3 stars are for Sennheiser HD 4.40BT and 1 Star is for Really unexpectedly fast delivery & Good packaging too. ---------→ Sound quality :- Now Coming to Sound quality of these Cans.... It was UNEXPECTEDLY GOOD for wireless 11k cans. It's Bit unique I would say it simply has Typical Sennheiser sound signature with More emphasize on Vocals and It is Mid Bass Centric and have bit less Emphasized Low end bass But that low end bass is still there and is presented in very Control way. I would also like to mention these Cans do sound bit better in Bluetooth Mode Specially Bass distortion is very very less and it's well presented and well Controlled. Also it does retain 80-85% Volume as compare to it's wired mode which can be really loud and In WIRED MODE these Cans sound superb and really good enough bass to even satisfy a bass head which I am not. Highs are bit rolled off and Treble detail is there but not much as you would expect if you have used any good Audiophile Headphones then you'll get my point. But Whole Treble / High freq spectrum is presented in such controlled way that these cans sound really really relaxed and you ain't going to feel any sort of ear fatigue. • So yeah these DO Sound BIT WARM BUT VERY RELAXED AS WELL VERY SMOOTH so you can use these cans for even 5-6 hours continuously without any sort of ear fatigue and these are very very breathable Headphones. Mind you I ain't an Audiophile but I tried my best to explain how these sound. Just for a side note I do own Audio Technica M50x and these don't sound as AGGRESSIVE & In your face and DOESN'T SOUND AS DETAILED as M50's. But I can guarantee you that You are definitely going to enjoy these cans like very much and these are fun to listen to RELAXED sounding Headphones. Also I have Tried Sony XB950bt, Xb650ap, xb450ap, Bose Qc35 ( Picture included ), Beats solo 3 ( Picture included ) and these do stand out and sound far better yes even better than all of those cans and Specially even better than 30k Priced Bose Qc35. Maybe bass heads will choose Xb950bt or Skull Candy Crushers which sounded very less details and they were totally bass centric. ------------→Pros :- 1) These are very light weight Headphones and earpads of these Cans are simply very freaking comfortable ( for small to Avg size ears ). 2) After 2-4 hours of usage once you'll get familiar with it's Controls then it does certainly have very simple straight forward Trigger button to pick up phone calls and to skip songs and for fast forwarding and approx all sorts of functions are quite easy to do with that Button. And Volume buttons do provide feedback which that Trigger Multifunction Button doesn't provide which is totally fine for me. 3) These are well Build Headphones for Specially it's price range and these surely do provide Premium feeling and These do have that minimalistic design and it's actually really Very Beautiful simple Looking design and very Public Friendly design so you can wear them in public while looking cool and without catching attention of many people. 4) Fit and stability of these cans is simply superb and once you'll wear them you can go to Gym, Running, for work out or any sort of activity. As these cans simply have good fit and doesn't slip from your head. 5) BT Pairing of these cans is very simple procedure and You can pair it with two different devices at a time and These do provide really excellent Bluetooth range as I was able to use even in my duplex house too. Also whenever you Power on These Cans simply keep bluetooth of your device Always ON as these cans do pair automatically with the device if that device is available to connect. 6) Call quality on these cans is simply superb and these certainly do impressive work as you can listen to your own voice too otherwise you'll end up speaking loudly while using these cans as Headsets because of Noice isolation of these cans. It's omni directional mic also picks up some background noises as well. 7) Passive Noise cancellation / Noise isolation of these cans is simply damn good and so good I literally thought I am wearing an ANC enabled Headset. There is minimum Sound Leakage even at 100% Volume and specially if you are sitting in a bit noisy environment like travelling in Bus so person sitting next to you simply ain't going to be disturbed at all . 8) These have quick pairing NFC option so without pressing it's power button Everytime you can simply slide your NFC enabled Android phone over it's Left earcup to simply pair it with these HD 4.40BT and these also come with AptX codec too. 9) Battery life of these Cans is simply freaking amazing. There was 30% battery left Even after 20-21 hours of usage at 100% volume and I also used these headsets for calling in that 20-21 hours usage interval. Specially It's audio plug is positioned in such manner as well it's included cable is so light that you won't feel like that you are using them in Wired mode. ------------→Cons :- 1) Your earsize should be either small or avg and if you are ears are large or way above avg earsize then your These cans might be bit Uncomfortable for you because it's Earcups are more suited for Small to Avg size ears. (Check M50x earpad vs HD 4.40BT earpad size difference in picture.) 2) These cans surely have bit more clamping force and you might actually have to adjust these after half to one hour But if you'll find that sweet position by adjusting them a little bit so you can wear these for hours and hours without any issue at all. 3) There is Bit of a distortion in Wired mode at 100% volume in like 2/3 songs outta 100 songs which are Mid bass Centric songs and naturally really really loud songs too & which I have on my iPhone 5s it simply feels like Bit overdriven for those 2/3 songs and due to that there is bit fuzz type noise in Mids other than that for rest of 97 songs these did a freaking job of sounding really good and really relaxed as well without any Sound & Specially bass distortion at all. ( I am pretty sure these are being overdriven for those specific songs ). 4) Carrying pouch or bag is bit of disappointment which I shouldn't mention for it's price point but still it's not something that reliable pouch which you would like to have for these cans. And So yeah this was my Review about it and Thanks for checking out my Review. Also I bought these for 7500 while they were on discount but these do certainly deserve 11k easily and I do recommend these to anyone looking to buy wireless cans under 11k. ---------→ Some Side Notes :- 1) Yes, These Cans do Require some burn in and after two week usage ( 4-5 hours on daily basis ) bass has improved so as other Upper Mids and treble has more detail now specially bass has increased and is being presented more tightly and it's bass now goes even more deep without leaking in mid spectrum at all and These do surely sound better after some burn in. 2) For Those WHO ARE COMPLAINING ABOUT LOW VOLUME in Bluetooth Mode....... - First Make Sure to Increase Volume of these cans to Max 100% as well as volume of your mobile media player to 100% as well. - Use High Quality 320Kbps Audio Files otherwise low quality audio files can result into low volume in Bluetooth Mode. - For Videos Use Mx Video player and use its SW Decoder and increase Volume of your music video or movie to 30 if you want to. I will keep updating this Review if I need to in future.

Je suis très satisfait de ces écouteurs. Je les ai achetés sans vouloir dépenser trop d'argent pour eux et je suis très satisfaite du résultat. Dès le moment où je les ai tenus dans ma main, ils se sont sentis comme de la qualité avec un design simple et discret. Dès le moment où je les ai mis, ils se sont sentis à l'aise. Ils restent en place malgré le fait que je penche la tête vers l'avant pendant que je prends des notes au téléphone - ils restent aussi en place pendant les travaux ménagers - ils ne changent pas du tout. Cependant, la qualité audio (en conjonction avec mon iPhone) est fantastique. J'entends ma musique avec des oreilles fraîches - j'entends des nuances que je n'entendais pas avant. J'entends les instruments individuels qui sont joués. C'est merveilleux. Je pense que la qualité est meilleure avec Bluetooth qu'avec le câble audio - peut-être parce que le convertisseur analogique-numérique dans les écouteurs est meilleur que celui de mon iPhone. Bien que le microphone soit intégré à l'une des oreillettes, la qualité du son sortant est également bonne. La portée Bluetooth est également bonne - je peux me déplacer dans tout mon (petit) appartement en laissant le téléphone derrière moi sans problème d'abandon ou de qualité. Je n'ai eu aucun problème pour apparier et basculer entre mes iPhones et mon iPad. Les commandes sont faciles à utiliser - elles sont toutes sur le côté droit autour de la jante pour que vous puissiez les utiliser avec votre pouce droit. La seule préoccupation, c'est que celles-ci ne sont pas des antibruit - la version antibruit en valait peut-être la peine après tout, mais je vais devoir les porter dans d'autres trains et d'autres avions pour prendre une décision à ce sujet. De plus, si vous utilisez le câble audio (par exemple dans un avion), les commandes de l'oreillette ne sont pas transmises à l'iPhone. Dans l'ensemble, je suis ravi de ces produits et je suis tellement heureux de les avoir choisis.

I love headphones. As such I have a number of different sets that I use for a variety of purposes. I generally use them for at home listening, and usually favour wired open-backed over ear headphones that avoid bloated or muddy bass. My current sets are Sennheiser HD599, AKG 702, Beyer 880 and also HD 598CS, and Bose soundlink II. I have tried a number of others that have had to be returned for a variety of reasons. I have wanted a Bluetooth Headphone for casual use, without it being so expensive that I would be afraid to throw it in a bag-and in these Senns I have found it. They are quite different to my usual style, but they represent great value for money. There are two main qualities that a headphone must have for me to consider it a 'keeper.' Audio quality and comfort. Everything else is optional. Comfort... I'll start with comfort as it was my biggest concern with these. Half the headphones I've tried have been uncomfortable, usually beacuse of my ears not fitting well inside over ear phones. It has often been the case that part of my ear touches the driver and that is very distracting. When I first unboxed these I thought they'd be impossible. The shape and size of the ear 'cavity' is incredibly narrow and small--yet they fit really nicely without irritating my ears. I think this is down the the very deep nd very soft pads. Although 'leatherette' the fabric is also less clamy and sweaty than others (such as the Bose.) Clamping forcxe is just right, and comfort is high. The other problem closed back headphones have is 'thudding' when walking. Although there is some of this it is not nearly as bad as other pairs I have tried, and on a par with the Bose. Sound.. Without good sound everything else is wasted. These have a slightly artificial bump in the bass, but it doesn't come at the cost of clarity accross the range. The highs are very slightly redcessed, but less so than I expected based on reviews-just enough to avoid the harsh sibilance that makes the Beyers fatiguing. Seperation and soundstage are both very good (for the price) and these headphones 'kick' when needed, rumble when required, but get the bass out of the way for more neutral or balanced tracks. If you look for headphones that promote extra bass as a feature then these aren't designed for you. The main word I would use to describe the sound is 'rich and full.' Other stuff. Bluetooth connects, battery is fine, they don't beep bchanging tracks etc. on android. They look fairly high end for the price range. The nearest competitor in my collection are the Bose, and I think I prefer these due to clarity and comfort, but they are both close (with the Bose being significantly costlier.) Closed back are unlikely to ever be my main headphones, but I am happy with these as a truly prtable experience tha retains good quality. I also tried Sony CH500(on ear) which are much cheaper but are the most uncomfortable headphones I have ever worn!

➤ Warum gekauft? Ich bin Pendler und habe mir einen guten Kopfhörer gesucht. Ich habe nun Jahre lang nur inEars verwendet und das hat mich jetzt genervt. Letztes Jahr hatte ich einen JBL Everest ELITE 700 Kabelloser Bluetooth Over-Ear Surround Kopfhörer mit NXTGen Active Noise Cancelling, Musiksteuerung und Integriertem Mikrofon - Weiß , den fand ich jedoch nicht gut (vor allem für den Preis). Dann habe ich mir den Sennheiser HD 4.30G Headset (geschlossenes, ohrumschließendes, geeignet für Android) schwarz . Mit dem bin ich eigentlich nach wie vor sehr zufrieden, ini letzter Zeit hat mich jedoch das Kabel zunehmend genervt. ➤ Bewertung Positiv ✔ sehr guter Klang bei Musik ✔ auch Podcasts (höre ich sehr viel) rauschen eigentlich nicht (einer meiner Hauptkritikpunkte am JBL) ✔ einfache Einrichtung ✔ sitzt sehr gut ✔ lässt sich gut und intuitiv bedienen (auch wenn die Knöpfe ein wenig klein sind) ✔ dezentes Design ✔ das Telefonieren geht sehr gut ✔ Akku hält sehr lange Negativ ✘entweder habe ich sehr große Ohren oder das ist eher ein OnEar Kopfhörer ✘ wird warm am Ohr ➤ Fazit Der Kopfhörer gefällt mir sehr gut. Er hat im Endeffekt die gleiche Passform wie mein "alter" HD 4.30G, jedoch zusätzlich die BT Funktionalität. Dadurch, dass er doch recht stramm eingestellt werden kann, achte ich genau darauf, wie ich ihn aufsetze, denn wenn ich das nicht tue, dann drückt es nach einiger Zeit am Ohr. Der Klang ist sehr gut, ich kann ihn ohne nachzudenken, intuitiv bedienen. Von mir gibt es, verdiente 5 Sterne (wenn man den Preis von 99 € berücksichtgt ist das sogar mehr als gerechtfertigt) Update: ich habe mir noch LTGEM Hart Lagerung Tragen Travel Case Tasche für Beats by Dr. Dre Studio Wireless Kopfhörer (Over-Ear) / Pro Wireless Kopfhörer / Sennheiser Momentum Kopfhörer. für die Aufbewahrung des Kopfhhörers gekauft. Da passt der Kopfhörer perfekt rein und das Kabel ist gut aufgeräumt.
