Review: Works fine yet inexpensive - I needed this to eliminate a ground loop hum between my PC and an external audio amp. Worked great. Note that there is a switch that must be flipped accordingly to lift the ground as needed. Audio quality seems fine since it’s only MP3 music. Probably wouldn’t buy this for a million dollar recording studio but for my needs, this was an economical choice.

### ⭐⭐⭐⭐⭐ Finally!
*by J***G on March 23, 2024*

To say I was skeptical is an understatement. I plugged this in to the RCA input coming into my PS Audio AMP and the 60Hz hum/Buzz is completely gone. I mean completely gone. I replaced electrical outlets, replaced cable and still have major noise. I installed this FMUSER RCA Audio Ground Loop Isolator and my music system now is dead silent even when I turn the volume up and there is no music playing. Great device. Get one whenever they are back in stock! So happy here!
