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

Picked up a RODECaster Duo audio interface, which, for the asking price, really should be able to competently produce a noise-free signal on its own, but unfortunately that wasn't the case, and no matter which headphone output I used, there was a horrific buzzing/hissing/cracking noise. Worried that I would have to return a product that I otherwise liked a lot, I looked into a solution, and one of these little ground loop isolators seemed to be the most recommended solution.This unassuming little box ended up being the solution to all of my problems! When I first plugged it in, there was no noise at all, which made me think that the isolator was stopping all signal from getting through, but as soon as I started playing audio through the RODECaster, I could hear everything clearly!The product also doesn't seem to interfere with high-end, high-impedance headphones either, with my Beyerdynamic DT1770 Pro 250Ohm headphones running beautifully through it. Thoroughly recommended if you're looking to try to remove interference from your audio setup

I got this when I was using a very expensive headset in a specific configuration. I was playing on the Switch, using the TV but wanted the audio to go through the DAC while still hooked to my PC to use the features.However... The length or the wires was causing a lot of fuzzy noise and crackling.So I got this, plugged my wires into it and it sorted it out, there's no more hiss or anything

Didn't work at all. The buzzing just continued. Returned for refund.

So simple and cheap, yet so effective. I had a ground loop on my car (a 2003 3.0i Z4) which meant awful sound quality through the new AUX input I fitted (Bluetooth receiver plugged in to cigarette socket created the ground loop). Was going to take it to an auto spark but saw this and it worked an absolute treat. The sound is crisp clear now. 100% recommended!

Eliminates the buzzing sound but Makes the sound faded and low.

Good job. Worked the best

Didn’t completely work but for price does the job

I connected, in my camper, the power for the laptop and external speakers to the 12 volts hub . Then I connected the speakers to the laptop ( to have better sound than the speakers of the laptop ) . The result was to having a HUGE buzz and crackling sound due ( according to my research) to "ground" ( negative) interference . Of course I use the same service battery, cannot do nothing different... Just to be sure I connected, temporarily, the power supply ( one of them, does not matter) to the engine battery. The noise was gone, so I proved that actually was the "ground interference" the problem indeed! ...I bought this "stupid" cheap little thing and ..ET VOILA' ...noise completely gone!!!! I am superhappy. Thanks -
