Btuty Ground Loop Noise Eliminator Only Eliminate the Hum Generated by the Common Ground Line Buzz Eliminator Plug-In Common Ground Line Hum Eliminator Noise Canceller

eDrum kit on one side of the room, mixer/amps on the other side. Each side on a different leg of the 110v N American mains power. Without the noise eliminator gizmo, 60 Hz screaming for attention. Plug the gizmo in, between the drum kit and the duplex outlet, hum goes to literal zero audibly and on the spectrum analyzer. Simple, inexpensive, works. If I were any kind of musician who needed 110v power for my drums, guitar, eCowbell, whatever, I'd sure keep one or two of these in my gig bag.

Useless.

Was getting a bad hum from all my speakers in my home theater when I connected an external amp. As soon as I plugged the amp into this, hum disappeared! Very happy with my purchase!

did not work for me , but it may for you

I bought this thing a couple months ago as a alternative to the Ebtech and it died. Completely out of nowhere. Really I only used it maybe 5 or 6 times in the studio rehearsal room and worked fine up until that point. Just the amp went complete blackout. I thought the amp had died. Luckily it was just this hum eliminator. Cannot recommend. Spend the extra few bucks and buy the Morley or ebtech whichever you find. Those work like they should. This one is junk.

Purchased in January of 2023, broke in March 2024. Yes, it did eliminate the buzz from my laptop when I connected it to my mixer. But the ground plug broke off now. I was able to find my Ebtech Hum-X and compare the two. Ebtech is built much more solidly. Don’t waste your money on the No Hum that is made cheaper and will break. Get the Hum-X.

Works

Still had a ground hum but this is likely due to the environment that the equipment is in. The plug seems to be good quality and works in some applications, just not mine.
