Review on 🔇 BESIGN Ground Loop Noise Isolator: Enhance Audio Quality in Your Car or Home Stereo System with 3.5mm Audio Cable by Christopher Bates

UPDATE (1+ years) Used 2 of these in my virtual pinball game and they work great. Now that I'm working from home, I'm listening to music on my new work laptop. Unfortunately, the outlet in our old house isn't properly grounded and I just don't have the time or energy to fix it. And so I get the classic 60 Hz hum. But NOT with this product! So I'm going to buy a third one for my office. ---------- Day 1 of use but so far I am very satisfied. I'm creating a virtual pinball game that involves assembling a bunch of electronics and equipment in a closet. (See photo.) The mix includes multiple power supplies and 2 low frequency amplifiers driving 2 sets of speakers - one for car noise, one for music, voices etc. No wonder I got it all working one day, both sound sources had lots of noise - probably ground loop hum and other induced noises - pops, crackles, hisses and just plain static. I tried many things but no luck. On a whim I thought I'd give this device a try, but I was pessimistic that it would work. But I just plugged it in, and amazingly it not only got rid of the constant hum, but also the sporadic pops and pops caused by things like powerful LED turn signals. I just bought 1 to try but I am in the process of ordering #2 for another amp.
