My service truck didn’t have Bluetooth and these worked great for playing music off my cellphone to play Xm radio.

It took some experimenting, but now that I know the steps to connect it, I can now listen to my vintage iPod on the Bose sound system in my new Santa Fe. And all my old music sounds just terrific! The price of this can't be beat either. Highly recommended!

El producto funciona, la quería para conectar como parlante a mi Alexa. Pero el detalle que me parece molesto es que al encenderlo, funciona bien, pero con el tiempo el sonido va ganando retraso que con 20 minutos, se nota mucho el atraso. Para solucionarlo, tengo que desconconectar del Bluetooth y volverlo a conectar; o apagar el dispositivo y volverlo a encender.

Works well, no issues and very easy to connect. I just wish the battery life was longer. Still a good device

I bought this to "add" Bluetooth capabilities to my Yaesu FT-710 - it's a bit annoying it isn't already included, but this transceiver fixed all of that. I love that it charges over USB-C (fewer cables to carry) and doesn't require an extra app or other nonsense to pair. You simply put the button on the slide into transceiver mode (TX), and then push and hold the button on the middle of the device. It'll go into pairing mode, then put your headphones in pairing mode, and both will automatically connect and audio begins broadcasting.We'll see how long the battery life lasts, but I was very pleased with the initial setup and testing I did with this transceiver, and I've already recommended it to other hams with the same radio.

Pretty easy to set up. But there is a lag in the sound when using these so if you are watching something using these the sound will not synch with the video, like a badly dubbed movie. Also if you are wanting to use these with headphones to practice a music instrument, that lag makes it impossible to use this device.

This thing took me quite a while to figure out. For one, I didn’t even know that this is both a transmitter and receiver. Though, that’s just more functionality, and not a con at all. To set it up you do have to read the instructions, probably a few times before understanding. A silly mistake I made while trying to pair it is that I forgot to put my headphones into pairing mode, so don’t forget to do that or else they wont pair, obviously. Once it’s all set up, I did feel as though it was too quiet. In some things I plugged it into, I could barely hear anything at all. I think by default it’s not going to be very loud, so you’ll need an external way to adjust the volume. For me I had it plugged into my iPod, transmitting to my Bluetooth headphones. On the iPod I turned the volume to the max and it was still very quiet. Then I turned it up on my headphones itself which solved the problem. After that it’s basically fully functional. I did notice the audio would cut for a brief moment, but it was very infrequent. Maybe once every ten minutes or something like that. If you could be patient with it and give yourself time to figure it out, it works just fine. You can also use it while it’s charging, which I did appreciate. It’s nothing special, but is perfectly adequate for me.

At first I loved this product. it works great and sounds amazing . The problem is the metal piece that you connect to it to the car came apart and the wires were showing and it stopped working. After a week. very disappointing. The price was good and delivery fast. you have to have a charger of your own to charge it it does not come with block to put the wire into to charge. it does come with the wire and it is short.otherwise I really loved it. To bad it had to break so fast.i am Leary about buying the same one because i am afraid it will break again. I don't want to have to keep buying itI was hoping it would last longer.

Sound quality is great, I use it in my car all the time, and the battery life seems good too.The range is very good, it can cover the entirety of an average Subway restaurant (I work there and use it on the speakers), but sometimes it cuts in and out if there’s a large metal object between you. Another thing is that when you first connect to it, sometimes it disconnects you and you have to connect again, but after that it works fine. If someone else connects to it it will do this to them, and then do it to you again when you reconnect. I don’t know about Android phones, but on my iPhone, when you turn it off, the little icon at the top of the screen goes away, but in your settings it still shows as connected, and you’ll have to disconnect to allow someone else to connect to it. If you choose to disconnect after you turn it off, when you turn it back on it will automatically connect. If you don’t disconnect after turning it off, when you turn it back on you’ll have to go into your setting and just tap on it will work again. It also registers to your phone (at least iPhones) as a pair of headphone with a microphone, however it doesn’t have a microphone, so if you answer a phone call you’ll have to switch to speaker so they can hear you. I’ve only used the transmitter (Tx) mode once to make sure it worked, and it seemed to work fine although the took a bit before it would connect to my headphones.Volume control is fine, although it’s much quieter than I feel like it should be. When I plug my phone into my car via a cable the volume levels seem about the same as the radio, but when I plug this in I have to turn the car volume up much farther to achieve the same volume level.Although it can be a bit quiet, it works amazingly. The weird connectivity stuff is the only thing keeping this review from being 5 star.
