Cable MattersGround Loop Isolator 3.5mm Noise Isolator Hum Eliminator for Car Audio and More

So here was my situation. I got a set of JBL LSR305s hooked up to a Minifuse 2. Had no issues as I got some nice shielded cables for it. Zero noise or hum. But recently saw a sale on a Monoprice sub so I decided to grab it as the sale was very nice. Sadly the inputs and outputs on the sub are RCA and my cables wouldn't work. So I got some new cables well reviewed on Amazon by a brand called Pig Hog. Well it didn't work out as intended. Very loud hum with the sub set to 80hz crossover. Like it sounded like I had an indoor air unit sitting under my desk. But with some investigation I found that it wasn't the cables. So I went back to hooking up my JBLs with their original cables that I had, hum is gone there, then I used the headphone out put to go into the sub giving me a way of controlling sub level without reaching under the desk using a trs to rca cable I had around. But while the hum was gone on the JBLs it was still very there on the sub. And thats where this guy comes in. Received it yesterday and after putting on the line to the sub all the hum is gone. Worked as intended for me. Great product.

Got this to solve some buzzing resulting in using both inputs on some computer speakers at the same time and it helped a lot! There's still a little noise sometimes but that's likely just the speakers' amp being turned up + the motherboard's onboard audio being imperfect.This drastically cut the buzzing out.Only issue is the included cable seems a little faulty, had to wiggle it and bend it around a bit to get it working fine in both channels. Nothing major enough to return it or anything.There are many brands since ground loop isolators aren't complex devices, I just went with this one since I'm a fan of Cable Matters' products from past experiences and it's been fine!

The one I was previously using in my car died so I needed a replacement. This one seems to be better build quality and you can also use your own Aux which is better than my previous one because that is what failed on the device but it was permanently attached to the ground loop, so this is leagues better. I paired the Cable Matters ground loop with a very high quality CNCESS Aux so I shouldnt have that issue again. Sound quality is great.

Works great! I bought it for my after market bluetooth that plugs into my radio. It's kind of cumbersome with it just hanging down, but it does eliminate the noise through the speakers that is usually there.

I've used 3 different 3.5mm Hum Eliminators, from separate manufacturers over the past 7 years; but I was never satisfied with any of them and was ready to give up on finding a decent one...Until I bought this product!Why it rocks:-Removes the nasty buzz from my laptop. (Just as advertised.)-Right angle 3.5mm plug. (Stays out of my way.)-The device quality is HIGH, with a soft material on the outside body.-It does NOT release a vapor into the air. (Like other cheap competitors.)-Low cost. (No-brainer purchase.)Note: - There are 2 stickers on this device:-1 large on the front;-1 smaller one on the back;these can be easily removed without hassle.Strong recommend!

It definitely removed all feedback. The problem is it also eliminated the low end. It was like my amp wasn’t on at all.

I have been having issues with electrical humming and static noise whenever I load up a a game on my PC . I have two inputs to a audio switch, one from my Mac Studio and another from PC . And whenever I load up a game there would a electrical humming and static noise.With Cable matter ground loop plugged in between my PC (source) and the audio switch, the electrical noise , humming & static is all gone!

Not so sure this made a difference in my case, yet to try it another way besides the car i had placed it in.
