2 Packs Ground Loop Noise Isolator for Car Audio/Home Stereo System, Ground Loop Isolator with 3.5mm Audio Cable

I have a soundbar attached to my TV but when the TV is turned off the soundbar buzzed, and it was loud! I bought these in an attempt to negate this, and they work incredibly well. I put one on each side of the audio lead, each doing their job. I suspect daisy chaining some more might reduce it to zero, but the buzz is barely audible now I'm happy with the results.

These are awful, dont buy. enough said.

Convenient way to eliminate ground loop noise for many audio applications.

I don't know what I was thinking..Complete waste of money.this might get rid of some ground noise, but oml at what cost!i would rather hear a bit of humming between songs, than the washed out sound these things produce.

Do the job :)

I’m a bit of a sound enthusiast and wanted my ps5 playing sound through my PC, so I could use my pc and ps5 simultaneously and have sound pass through my amp.When connecting the aux sound card to the in line on my pc there is an horrendous beeping noise that makes you feel like you have tinnitus.However, connect one of these isolators to each end of the aux and it nullifies that sound to a point where it’s almost not detectable. Great value

They don’t do anything. I still got feed back.

Working great. Eliminates bad noise from the audio, at the cost of a bit of clarity (makes it a bit mufflier).But a buzz is so much worse
