Dura poco la batería sin embargo funciona sin ningún problemaEstablece bien la conexión

I tried this transmitter/receiver because I was looking for something very specific- a way to take sound from my mixer to my in-ear bluetooth headphones wirelessly without a body pack. The description said it wasn't made for live sound, but I thought it might work anyway, and it would be really useful to eliminate the body pack from my IEM setup. But I should have trusted the description- this transmitter (or maybe bluetooth connections in general) just isn't fast enough for live sound. There's a noticeable delay, even when transmitter and receiver are very close together.However, I learned a few things while experimenting that might help you:1. The sound is good, no problems there2. This transmitter/receiver CAN connect to a device that doesn't have a screen or interface. I was worried about that. This paired to my AZ09 receivers, even though neither device has a screen or could pick the other device out of a list. If you're having trouble, make sure the other device isn't already connected to something else- it has to have an open connection slot in order to automatically pair to this transmitter/receiver. Disconnect it, then turn on the transmitter/receiver again, and it should connect automatically. It took a few tries, but I made it work.

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.

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.
