The device works on received, on transmitting had a delay like a second so if you wanted to used on a tv or a game console like a wanted to used it, is not going to work, the delay is very distracting, so going to used it on old car. You can't use it while charging because the sound get a lot of noise so is battery use only. Came in good bubble wrapping and took 36 days since order.
perfect. thanks
