Device installs easy and connects to my phone quickly, but it emits a high pitched whine through the speakers of the car, and the people on the other end of the phone call hear the whine also

There is a fairly quiet high pitched whine that you notice when you don't have the radio on, but you can unplug the unit when not in use to eliminate this problem

My only complaint is that the dual USB charger included produces a barely audible high pitched whine when in use.

Setup was easy and quick, although there is a high pitched whine when no music is playing

My son's mention hearing a high-pitched whine through the speakers, but the whine is much lower than my previous Bluetooth transmitter/receiver and much much lower than plugging directly into the auxiliary jack from my iPod or smartphone (when they're charging).I'm ordering a ground loop noise isolator to try further reduce the whine

Sound quality is pretty good, but I do get a high pitched whine similar to a ground loop whine that I did not have when not using this unit

The only drawback is there is a high pitched whine caused by a ground loop

n’t trample the product in that regard

the soundbot is just hanging b/c the adhesive isn't strong enough.

We gave it 4 stars b/c we'd like for it does not connect to more than 1 phone.
