I bought this based on the good review rating, however it is a mystery to me why this has been rated so well. Perhaps expectations are low for most people. For me it is unacceptable. During the non-loud moments (playing music or a phone call) you hear a very annoying static sound, similar to the sound of bacon frying. I have tried this on all three of our cars and the results are the same. If you crank up the music and the music selection has no quiet passages, the audio quality is barely acceptable.
