Isobel Upgraded Bluetooth 5.3 Transmitter Receiver 3-in-1, Wireless 3.5mm Audio Adapter for TV PC Headphones Home Sounds System Car/CD-Like Voice Enjoyment

On long flights, my wife normally uses her Sony CH-700 headphones, for the added convenience of noise cancelling, while enjoying a better audio quality, than the one delivered by the standard wired ear buds provided by the service on board. But I observed she normally had problems with the wired connection, because the wires would get entangled with the night cover the irlines provide. Therefore, and in order to minimize cabling, I looked for a Bluetooth Tx that would have its own energy source to avoid the cabled connection between her headphones and the audio - jack and the usual USB Power cable these devices are provided with. I looked up the highest amazon rating reviews, before ordering, and I was gladly impressed by the audio performance of the unit I purchased. I was curious, however how it would work on the airplane,with so many other bluetooth devices in the neighborhood. In order not to experience problems on the plane, I paired her headphones with the Tx/Rx put in Tx mode prior to boarding. When she turned her headphones on, once on the plane and simply leaving the Tx/Rx device in the seat pocket, results were outstanding. And since the battery life on both devices is similar, about 5 hours, she could use the system for the whole 12 hour flight (considerng sleep time) without having to worry about recharging and not experiencing problems associated to the cables.

In my church, we have a mix of live and recorded music we use. I used to have someone sitting by our sound board, with a laptop. When we needed music, they would start it. This winter, we moved into a smaller worship space and I used a little Bluetooth speaker I had. When we moved back into our larger space, I wanted to continue to be able to run the sound from a tablet, but our soundboard/ amp thing didn't have bluetooth. So I got this, got an adaptor and ran it right into one channel on our board. Since the board takes a larger plug than this has, I did have to get an adaptor. But I suspected I would and ordered one of those when I got this receiver. Now, when we have some hymn or recorded music, I just have my tablet, open that file, hit play and it starts. Several of my older members seem pretty confused, they think I am doing magic or something, put a button at the pulpit and the music starts. I do have to get it "connected" before the service as it does say "waiting for connection" and "connected." But I am a good 20 feet away from the board, and no problem at all staying connected during the service.I used it for 2 weeks (two Sunday's) and then forgot to shut it off. So week 3, I plugged in a portable power supply (battery pack) to charge it as the service was going on. After the service I brought it home, plugged it into the wall and gave it a full charge. No problem going for a few hours, two Sunday's, but it was dead after a week (as I would expect). Just have to remember to shut it off, and bring it home every few weeks to give it a charge.It is perfect for our church, small, was easy to install, and it easy to use.

This was a useless waste of money. Didn't work out of the box. Had a high pitched whine so couldn't use it. It went into the trash.

Small and easy to work with. I got it for my PA system to play my soundboards over it. Halloween, Christmas, special events, generally to mess with people. Paired with 200watt 2 speaker PA system/siren (obviously I don’t drive around play a siren) paired further with soundboard apps on a smart phone and you have endless possibilities of messing with anyone and everyone. Right now it is Halloween so you do the math. Took my PA system to new level obnoxious and pointless. Hehe.Battery life seems legit. It does time out and turn if not used so don’t worry about it staying on and running down battery. Recharge time is quick. Cord is long enough to plug in a tuck away somewhere less obvious but the more between your phone and receiver will obstruct signal and shorten range. I set mine on center arm rest and can’t still be in the gas station and mess with everyone inside through my phone

The ZF-360A is a very nice product, but NO stereo sound, product details on this part we're not specified.This is a wireless audio transmitter and receiver. 3 in 1 5.0. Signal distance is around 33 feet give or take.Has a 300mAh battery.I gave the sound quality and overall rating a three-star, because it's mono and not stereo, otherwise it's clear and solid.I wanted to use this for my old stereos from the '70's, and boomboxes from the '80's. I'll have to come up with something else. Mono is boring, and you tend to lose some of your music because it gets canceled out by a mono channel.At first I had trouble pairing this with my Bose SoundLink color Mini. My test was using my very old and most favorite SanDisk Sansa Clip+ 4 GB MP3 Player (Black) (Discontinued by Manufacturer). Line out from the 3.5mm stereo jack, to the TX input of the Transceiver, switch on the side set to TX. red light flashing. My Bluetooth speaker was already to be paired waiting for a signal. Still nothing. I tapped the power button and still nothing. Then I pressed the + button and got sound. Happy I was, till I realized everything was in mono and not stereo.I checked all analog connections, nope! no problems there. I ran a phase check from some tracks I have from Bass Mekanik. A voice from normal to high would say, L ch then R ch several times. On this test track sound came from both speakers, proving to be a mono channel through the Bluetooth transceiver. Next track, a voice that would say phase check, in phase, followed by a tone from high to low. Out of phase, followed by a tone from high to low. Ordinarily you would hear an offset between the two speakers. In mono it is dead silent, which concludes this part of the test normal through a mono channel to stereo amp.Hope this additional information helps with other audio applications you may have.
