Review: Perfect tips for KZ ZS10 Pro X and JBL Vibe Beam for large ear canals - Finally found foam ear tips that fit my KZ ZS10 Pro X earphones without being loose around the headphone tip or inside my ear. I have large ear canals so these foam tips expand comfortably isolating external sounds giving my music a deeper bass sound than the original silicon tips, and no itch!. Best of all? the price, they're not as expensive as other brands. They also fit the JBL Vibe Beams, same fit and audio bass improvement, but just as all other earbud tips for these Bluetooth with a case, they don't fit properly, I have to remove them from the earbud so the lid closes properly to charge. Highly recommended.
Review: Nice and a Good Value - Pics show them on my Shure 425s. I will also use them on 535s. I have used Comply (expensive and to me too soft/not durable), and a variety of other tips. These rate at the top for balance of comfort, quality and fit. Fit on the earphone is great. Not too hard to get on, but firmly in place once they are. They are shorter than Comply ones. And similar length than most. Most important, they still get in my canal plenty to isolate. But if you have a crazy deep canal and are familiar with tips know that these are not extra long. Quality. Time will tell but first impressions are very good. They are soft, but not so soft they tear. (A problem I’ve had with others). The skin of the foam is less porous than other lower price point ones. Which in my experience will help them last more than a few sessions. I’ve put these tips on and taken off a few times sitting here. They seem more durable than others. Comfort. To me they are great. Definitely firmer than some but not in a negative way. They return to shape well in ear, and seal with no discomfort or too much pressure on canal. Sound is not effected. I’m sure due to the great sizing they have figured out. Isolation is comparable to Comply, which based on price is the “premium” product. These do compare. Bonus- these shipped in a convenient compartmented case. Not anything expensive but useful (I’ve tried all sorts of storage in past and I like this best). So the seller gets a nod for the thought. Not a negative but if the seller had these same quality in Red and Blue they would be perfect. Or Red and Black. On stage it’s easier to know which ear on quick glance with different colored tips. Just an idea. Overall I will buy these again and recommend to others.

### ⭐⭐⭐⭐⭐ 5 stars easy, SF2 & SF0
*by G***. on January 26, 2025*

I am a purchasing consumer posting an honest review of the SF2-MEDIUM which I bought. I use the SF2-MEDIUM with my JBL T110. I receive a second set SF0-SMALL for providing user feedback. I use the SF0-SMALL on my Truthear Zero Red. [1/26/25] Easy 5 stars. I would not hesitate to buy these again. I bought the SF2 size in Medium for my JBLT110. Fit is perfect, they slide on firmly and do not fall off. Sound isolation is improved considerably. They feel like foam-roll hearing protection earplugs. They have much less "suction cup / vacuum" feel on my eardrums. The JBLT110 with factory silicone tips have a very pronounced 5~7 db treble boost above ~6K, that honestly sounds like nails on chalkboard to my ears. These sonicfoam tips help to tame that treble boost for an overall better sonic presentation. I am not new to in-ear monitors and foam roll type ear-tips. My first set of IEMs was a Sure E2C 15+ years ago and I have owned various models from various brands since.... Jays, Sony, Truth ear...etc. What's nice about these Sonicfoam tips is the foam expands slowly in my ears, so I can take my time inserting them. Its NOT like a beat the clock... quick before they re-expand kind of thing. [1/28/25] I received a second set as a favor for providing user feedback. This second set is a SF0-SMALL for my TruthEar Zero Red. The Zero Red is well known for having a HUGE sound output tube, almost 7mm diameter. The SF2 tip inside diameter is way too small. The SF0 fits the Zero Red perfectly. Not too tight and not too loose. They are very similar to the OEM foam tips, except the Soncfoam material expands much slower so I do not have to hurry/rush to insert them. As far as sonics and comfort go they are an exact match to the OEM foams. [2/20/25] After almost a month these foam-roll tips are still going strong. They do show very slight signs of wear, but nothing significant. They are maybe still a solid 95%, and they seem to have plenty of life remaining. I use the SF2-MED with my JBL T110 EVERY night to fall asleep listening to waves and rain forest sounds. I also use them during the day to listen to music and YT vids. I literally roll around and fall sleep ON THEM every night. No soreness or discomfort of any kind paired with the small JBLs. I have equally positive results with the SF0-SMALL on my Truthear Zero red. Although I don't use those nearly as often as the JBL T110. I will post a follow-up to this review if my opinions change.
