Review on 🔇 ZIOCOM Ground Loop Noise Isolator: Eliminate Buzzing Noise in Car Audio and Home Stereo System by Otto Suarez

I use these to replace a bulkier radio. I bought two ZIOCOMs, used them in two different situations, they both worked great! One was used between my computer and the audio mixer that feeds the speakers (significant noise eliminated!), and the other between my stereo and my TV (significant noise eliminated!). There was no noticeable reduction in noise levels, although I didn't conduct an objective test. Because it worked so well, I'm buying a third one for my car to get rid of the audio hum between the Bluetooth receiver (which receives audio from my phone) and the car's auxiliary jack. Great compact product!
