Before choosing this article I have tried the equivalent at Com One and Delkin. This Bluetooth receiver is definitely over! The Com One not distorted sound but knew very frequent sound interruptions. The Delkin did not cut the distorted sound but too: no bass or treble ... The Real Cable iPlug BTR meets my expectations: from the pairing done, I can see the settings of my stereo after the test Delkin receiver. The bass is full, the present acute, very sufficient volume. About pairing: it was almost instantaneous with my Samsung Galaxy S smartphone (1 ..) but required a reboot my laptop running Windows 7. After the restart, no worries. I can finally listen to Deezer in good conditions :-) I recommend this bluetooth receiver for the quality of sound reproduction, undistorted, unlike the two other receivers I've tried before.
