Adapter high quality, the 20m announced signal are well respected, 10m through 3 concrete walls without problems. I use it on an amp to play sound from my iPhone and my Mac, the sound is played smoothly and both devices can coexist on the same receiver. No difference in quality depending on RCA or 3.5mm jack. Attention to the size of the receiver as well, I had not read the dimensions in the features, it is fairly small: therefore weight problem, the cables connected to the adapter are heavier and lead him, he n ' is not stable within the set or allow plenty of slack in your cables. It remains white when no device is connected, and turns blue when the connection is made. Very satisfied with my purchase, a small system with an adhesive was more to fix the receiver to the desired location.
