I have this product attached, using the optical connection, to a TV so my wife and I can enjoy shows / movies late at night without disturbing children. Both our Bluetooth headphones connect quickly and the ability to individually adjust volume it a great feature. The beauty of using the optical connection, and powering the device off the TV USB, is I can have the device connected and turned on and can use the headphones and/or the TV speakers at the same time without having to plug anything in or switch anything on. When using the headphones I simply turn the TV volume down to 1 so it cannot be heard - this has no effect on the headphone volume. We are very happy with this product it works exactly as advertised.
