ZIOCOMGround Loop Noise Isolator, Noise Filter, Eliminate the Buzzing Noise for Car Audio/Home Stereo System with 3.5mm Audio Cable

I had recently bought a car play screen for my 2012 plate Astra, and using aux, there was alot of interference/static even at lots volumes without any audio playing. So i got this and it has completely got rid of the noise. Highly recommend

Seems to do the job, no noticeable loss of sound quality or volume - though my hearing is a bit knackered so I may not be the best judge!

Works well to reduce noise, purchased because my sons RTX 4070 was spewing noise which was being picked up by his KRK Classics.I first tried rewiring the RCAs which helped slightly (the solder connections weren't the best) however the noise still remained.Ideally I would move to a balanced setup but I will need a direct injection box and balanced leads, this was purchased as an interim measure and works well to reduce noise at the expense of a slight reduction in volume and a suppression of 'punch', still the result is far preferable to the buzzing and whining that was present before.

Completely cancelled the annoying humming and buzzing on the powered speakers connected to my PC. Saved me a fortune as I was looking at replacing my PC because of it.

Recently installed an Android display in my car and I was getting really annoying ticking and hissing interference when listening to music, this little device has solved the noise problem and improved the sound quality.

My older Merc CLS stereo doesn't support BT music from phone, so I need to connect via AUX socket. There was always a little hum/drone when music was played this way. I'd read a review for AUX noise isolators and wanted to give it a go for the sake of a few quid. Perfect- buzzing is completely gone

Adds more static and makes volume quieter.

OMG works a treat. No more interference through the AUX port from car to my android screen.
