Mpow Ground Loop Noise Isolator for Car Audio and Home Stereo System with 1 Meter (3.3Feet) Extended 3.5mm Audio Cable, Black

My baby is my 2007 Chevy Tahoe LTZ. His name is Lightning The Queen. I bought him new so many years ago, and now that he has 210,000 miles on him, he doesn't like it when I play music though the AUX cable and charge my S8 at the same time. He shows his displeasure by making awful screeching noises and high-pitched whines through the Bose speakers because he doesn't like the ground loop created by the phone, charging port, and AUX input. Or something. I'm not an electrical engineer, I'm not even that smart, and I'm blonde. So anyway that meant that for years (since I switched to Samsung S phones from Motorola, come to think of it) I had three choices: 1) Listen to my music and watch my battery dwindle to nothing, then charge and switch to [ugh] the radio; 2) Listen and charge and crank it up so loud I could barely hear the static and high-pitched whine; 3) Put all my music on CDs and party like it's 1999.That is, until I bought this tiny marvel![ANGELS SINGING ON HIGH]I've been dealing with this for years. YEARS! How did I not know there was a solution for, like, $5?! Oh yeah, that's right, blonde, not smart, not engineer. Anyway, take my uneducated, flibbertigibbet word for it and BUY THIS THING. You plug it in, plug in your AUX cable, NO MORE NOISE. At least in a 2007 silver mist Chevy Tahoe LTZ with 200k+ named Lightning The Queen.Oh, some reviewers argued about decibels and bass and blah blah something; I could discern no difference whatsoever in music quality, although to be fair, I had "Rolex" on repeat so maybe your more highbrow musical ears may hear something different.Happy listening! I sure am now!

Disappearing Aux option BMW E46 - Problem Solved!I have a 2005 BMW 325i.I installed an aftermarket Aux cable (eBay) and it worked for about two days. On the third day, the Aux option on my stereo disappeared. It was completely gone. After disconnecting/reconnecting everything, taking the negative cable off my battery, reading every post on the internet and researching having my stereo coded at the dealer, I came to the following conclusions and fix.1. If you do not have an AUX option on your Business CD prior to installing an Aux cable, then it probably will not work. Aux is only enabled on e46's made after 2002.2. Installing either the OE AUX cable or an aftermarket Aux cable may not work consistently or may cause your AUX option to disappear completely.3. If your Aux option disappears, you do not need to have your radio coded at the dealer. If the Aux option was enabled before the cable install, it is still there. More than likely, the radio is no longer recognizing the Aux port due to a Ground Loop fault. This will happen most often when your phone is plugged into a USB charger and the Aux port at the same time. (I won't get technical here - there are many posts about this on the internet and even a DIY on how to build your own cable.)4. Plugging a Ground Loop Isolator directly into the Aux port will probably fix the issue.With the car and stereo off, I plugged the Ground Loop Isolator into the new Aux port and my telephone into the opposite end of the Ground Loop Isolator. I then turned the key to the first position. My Aux option instantly reappeared on my stereo and it is working great. I can also charge my telephone and use the Aux simultaneously now.I hope this helps someone else avoid the craziness of trying to solve this problem. Do this first!

Fantastic piece of technology. I struggled with engine grounding issue/noise for almost two years. I have tried everything from ferrite beads to shielded cables but in vain. The only solution was to not charge my bluetooth receiver whilst listening to it. But I stumbled upon this awesome piece while looking for a 4.1 bluetooth receiver. Works as advertised. It is slightly chunky compared to your ferrite bead type solution but if you have a hidden aux port like I do in my car, you wont even see it. Completely removes the signal noise (well not completely, I have not tested it out with an oscilloscope but trust me human ears wont pick up the noise anymore). I am thinking of getting this again for my gaming PC where sometimes I get a bad whine when the GPU is on full load. I will test it out and update if this fixes that issue.Note: I plugged this guy directly to the bluetooth receiver to take this picture but is normally plugged directly into the aux input behind the console. The cable on the device is also replaceable. It is basically a cuboidal cylinder with one headphone jack (3.5mm) on each end. Very solid build.

Absolutely a little gem. So, my specific use for this product is probably not a common thing, but I thought I'd describe it in case someone else has the problem too. The ground loop noise problem was happening between a PC sound card input and a two-way radio being used as a receiver. We are using the audio from this radio to feed the PC to provide audio from our ham radio group's repeater to Broadcastify. Prior to using this device, there was this constant "whine". It sounds similar to the whine you hear on a commercial airliner when you plug your headphones in - that high frequency alternator whine. The instant we put this inline between the PC and the radio, the problem went away.I highly recommend this for similar ground loop issues. It will probably solve your problem!

This tool fixed a static problem I had when connecting 2 computers. My setup is I have a Windows 10 PC and an iMac. My headphones are plugged into the Windows 10 PC and I wanted to listen to sound from the iMac, but I didn't want to constantly switch my headphones between the 2 computers. So I connected the iMac headphone jack to my Windows 10 PC line in jack using a 3.5mm male to male cable. But there was a loud static noise. When I inserted this ground loop isolator between the 2 computers, the static went away.

I needed this for eliminating the noise sound from connecting a AUX cable from my monitor to PC, for the reason that I want to listen to my Nintendo Switch in-game sound and Discord's voice chat at the same time using a headset.Before, there were noticeable for sure, and as soon as I plugged this idolator on, they were all gone! Easy and no hassle!If anything changes in the future, I will adjust this review, but right now I am very satisfied :)

I use this to capture audio from handheld gaming devices that don't have reliable audio output besides 3.5mm audio jack. I bought a different one and it had an issue on the one channel not playing audio. This works like a charm.

Perfectly removes background hum from my ipod when it is charging and playing through my car stereo. Very happy with this and would highly recommend.

I have no idea why bluetooth device manufacturers do not include this product with their devices. This was a must to make my bluetooth functional on my motorcycle with the MTX Bluetooth Controller. This 100% works as advertised and hopefully will last a life time.
