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.

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.

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 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!

The speaker must be actively playing audio (green light) when you turn it off, otherwise you get loud pops, it can't be on standby mode (red light).

I had little faith that such a small little cheap item could fix the feedback issues i was having. I recently bought a xbox series x and was trying to have the audio play from my monitor back into my PC so i could use my nice amp/dac and headphone setup. Well if i plugged the monitor into x570 mobo (has realtek audio card built in) it gave me horrible feedback. If i went from controller to PC, it was fine, but who wants a cable hanging off your wireless controller? no one.So i bought this Ground loop isolator. Instantly resolved my issue and i can now enjoy my CFB 25 in outstanding audio clarity and positioning.

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!

Lo compré para nuestro coche, sustituyendo uno que se venÃa con el receptor bluetooth y que se perdió. El ruido se quitó de inmediato.Me gusta que no tenga un cable integrado, sino que tiene conectores en ambos extremos. AsÃ, si el cable se daña o quiero usar uno distinto, puedo cambiarlo.Además, lo elegà porque el cable incluido tiene un conector en ángulo. Asà queda prácticamente plano en el tablero del auto y es más difÃcil golpearlo.

After receiving a Samsung F32TU874VN monitor from work, I thought I had the perfect docking setup:My laptop connects to the monitor via Thunderbolt and the monitor does the rest - powers it, acts as its display, passes on sound to my 5.1 system, and connects it to USB peripherals (mouse, keyboard, etc.).However, my dreams were shattered once I noticed the awful static coming from my speakers.As the days went on, it became harder and harder to tune it out.I tried all kinds of variations to the setup but it seemed that, as long as my monitor was involved in any way, there was no escape from the sound interference.Enter the Cable Matters Ground Loop Isolator. I simply inserted it between the monitor and sound system and, voila, the interference is gone!

Avevo un problema di ground loop nelle casse del pc dovuto alla GPU (il rumore varia in base al carico, e sparisce se collego gli altoparlanti ad un alimentatore diverso dalla presa USB della motherboard), è questo articolo sostiene di risolvere specificatamente tale problema.Una volta collegato il rumore di fondo non solo non è sparito, ma sembra addirittura più corposo.Assolutamente inutile, enorme spreco di tempo tanto per me quanto per il corriere. Reso immediato e una stella, ma solo perché non è possibile dargli zero.

Quel soulagement ! Enfin mes enceintes ne font plus un mini grésillement presque imperceptible quand je bougeais la souris...
