I tried to hook up my phone with various aux cables, and inevitably the sound quality was terrible, with the sound cutting in and out and making loud scratchy noises if the cord was bumped even the slightest bit

Loud buzzing noise through the speakers when music or call not active

In the mean time, my sound system made an awful thumping noise until the unit synced with my phone

Didn't work for my wife, makes noise.

It gave a high-pitch static noise through the car speakers, when the audio wasn't playing and the car stereo was in aux mode

Once you start playing music the noise disappears and works well

I thought because its inexpensive it would have some type of static noise, but it's pretty clear sound

But.....I cannot stand the hissing noise while Charging the receiver, there is a simple fix by buying a aux filter

I hear a humming/ static noise but when is doesn’t do this the audio on this is amazing

When you use it while charging a static noise is quite annoying

Makes funny noises when charging

So it gets pretty annoying when you are in the middle of a jam and it starts making crazy noises and you can't get it to stop

No scratchy noises at all, crystal clear music .

Static and noise.

This thing works great, but when nothing is being played it makes some God awful static noise

Sound quality sounds alright, and it makes a weird clicking noise when nothing is playing but that may just be my car.

The only thing I am slightly disapointed in is that my music is no where as loud as I like it however, over all I am happy.
