The purpose of this for me is to set up a Bluetooth headset to work with this device and play TV sound through it without taking it into the room and the rest of the Disturbing family, my dad is hard of hearing, his TV is on volume 63 and the rest of us can't hear what we're thinking about it. I said this in front of the TV, it had all the necessary or necessary optical and audio cables to connect it, it pairs with multiple devices, uses without problems, it transmits or receives, I used it in transmit mode to transmit the sound TV to the headset , the quality of the sound was very good and had a very good range on the device for connecting to a bluetooth headset. The photos I have attached are of the headset I used with a rechargeable headset which I also got from Revain and it lasts a very long time, he can hear it loud and clear and the rest of us can do standard audio levels tolerate.
