Mpow Ground Loop Noise Isolator for Car Audio and Home Stereo System with 1 Meter (3.Feet) Extended 3.5mm Audio Cable

We were experiencing a lot of interference noise and humming in our '09 Scion, added this and speakers are clear, no hum or buzz, and I can charge at the same time without any hum or buzz or static. Wish I'd purchased it earlier. The cord is long so if your audio cord is also long, there's a lot of extra, but throw a velcro wrap on it and you're good to go.

Nice product! This noise isolator helps alleviate unwanted high end sounds that is sometimes common when operating with electrical cords, power cords, system cords, I/O cords, etc. The noise isolator can assist in providing that ‘crisp’ sound that may make your sound — sound live & personal. I used it while operating an eight speaker connection on an iPhone. Quite a bit of persons enjoyed the sound.

I'm sure this product has lots of other practical applications. But I've used it for one thing and one thing only--with my Mix Amp Pro TR. Specifically, I use it for the Stream Port that I run from the Mix Amp Pro TR to my PC. I had major hiss/buzz from the ground loop I was creating. What's worse is that I thought I could fix my problem by following a guide, but no luck. I figured this product would be worth the $10 just to try it out. It was worth every penny! Hiss gone. Buzz gone. Easy to install. It just works. So if you have buzzing or hissing, give this a shot. $10 means you're not risking much.

I use my smartphone to listen to music while I sleep. I connect it to a set of amplified speakers, and for the last 5 years have had no problems with pops, buzzing, or ground loop hum when using my HTC One M8 phone (as it has a built-in ground hum isolation circuit).Recently, I replaced the HTC with an ASUS phone which lacks the ground hum isolation circuit... hence my need for an inline device that would eliminate the pops, buzzing, and ground loop hum.I connected the MPOW Ground Loop Noise Isolator, and found that not only did it NOT stop the hum, but the hum is literally TEN TIMES AS LOUD.I tried reversing the connection, and using several different audio cables to no avail.I guess by "Ground Loop Noise Isolator", they mean isolates the ground loop noise so that's ALL YOU HEAR.

My KRK RKT6 way too sensitive to any power junk and make that noise y'all know. I tried a ton of different filters. Mixed power outlets. Reinstalled drivers and played around with drivers and ac settings. I even bought used amp to connect to pc via optical cable and get rid of that crazy annoying noise. Nothing helped except that simple device. LOVE IT!! Thanks a lot! I hope it'll work for you as it does for me.

overly enhanced and distorted bass. this effect is even noticeable on podcast soundtracks. it pretty much makes it impossible to listen to any music with a significant bass line. for me, this is unusable.having seen anecdotes about being too hard to return and due to my laziness, i'm just going to put this in my to-be-recycled e-waste pile.got this one instead...much better for a few bucks more: https://smile.amazon.com/gp/product/B01N10AQ76/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

I bought this for a specific speaker, and it didn't do anything BUT I notice I had a slight buzz on my laptop headphone plug and it cleaned it up like magic!!! Love it. Use it everyday.
