The voice quality over the public address system is okay, the sound at the opposite has also been described.
Bad:
If the mobile phone is no MP-3 player is running, is often a fairly loud noise or a poorly tuned FM station heard (the stop once again music is played).
Sound quality because the heights are issued under a fairly distinct hissing.
Please note:
As stated in the instructions for use, the plug must be really plugged always after starting with the engine running, because the device needs to be reconfigured and re-coupled otherwise. If one considers that, for the next time, however, a sufficient pressure on the main button and the music is there again where it left off.
Conclusion: As a supplement for radio equipment without Bluetooth meaningful upgrade. Sound and handling could be a bit better. The price is offered for the value at the upper limit.
