Review: Excellent product. Seamless connection and serves the purpose completely. I used as a bluetooth receiver for my very old sony sound system using optical cable.
Review: Update: Tx Config: Using it to transmit audio to headphones., using AUX-in - working fine but need a good quality aux cable. the provided cable is not of good quality - there is bit of audio distortion if u set the volume to max. - the transmitter is bit noisy, when there is no audio playing. but once the audio is fed, the noise goes away (more like suppressed). - some headphones reconnect automatically and some needs to be paired almost every time. Not tested following config: Tx with Optic, Rx with AUX, Rx with Optic, by-pass Overall: good product, perfect for my use-case. Just buy a quality aux cable.
