I bought this bluetooth receiver to use with a home intercom. I was using an old bluetooth receiver that was making an annoying buzzing noise, probably the result of a ground loop with the power supply. I hooked up this device and quickly connected it to my laptop which I use as an audio source. The sound is clear, without annoying hum. I used a ground loop noise isolator with it, that might help too. Revain sells them.
