WisWinDa 3.5mm Pro Audio Noise Isolator/Noise Filter with Gold Coating AUX Audio Plug No Affect Bass
Portable Size Aluminum Shell Hum Eliminator/Ground Loop Noise Isolator
WisWinDa Audio Noise Isolator Could Perfectly Eliminate the Noise Caused by Current.
WisWinDa 3.5mm Audio Isolator groud loop noise isolator is a portable design and “plug&play” direct box device.
The sound source and the input terminal of the isolator form a loop separately, and the output terminal of the isolator and the load also form a loop.
There is no physical electrical connection between the front and rear audio equipment, thereby ensuring electrical isolation and achieving the following purpose:
1. Purify the audio signal transmission, utilising the unbalanced signal transmission mode, which could be sure that the signal will not have interference noise caused by the length of the cable;
2. Eliminate the interference noise caused by out-of-phase power supply;
3. Eliminate the interference noise generated by the ground potential difference;
4. Unplugging and plugging signal cables in accidents or emergencies will not cause sparks due to voltage differences, which protects the safety of the front and rear equipment; the power line is divided into A, B, C three-phase and the neutral line L. The general equipment is a single-phase power supply with a working voltage of 110-240V, using L, N, G (safety ground) three-wire safety sockets. In actual working situation, the distance between the sound source and the power amplifier and the simultaneous interpretation host is very far in many cases, and there will be different power supply situations: cross-phase lines, and different safety grounds (G).
Suitable for almost all large-scale outdoor performances, lightning protection, sound engineering, conferences and series of audio equipment systems such as entertainment venues and exhibition halls are protection and noise reduction equipment connected by audio and video systems.

I had a little static in my cars aux so I used this and now it’s gone. It’s made of high quality aluminum so it can withstand temperatures and abuse. Only downside is I wish it was made with an angled input because it touches the lid of my arm rest when I shut it and after so long it breaks the connection. I’m on # I just had to order a new one after a year.

I got a Bluetooth adapter for my car but it came with an isolator that made the bass sound like crap. When I got this and plugged it into my Mike Levinson sound system it sounded flawless. Highly recommend. Great build quality too.

Had a terrible buzzing noise coming from my speakers in the car when I plugged into my phone for a source. This did not do a single thing. Waste of money!

Finally having used several ground loop isolators, this one has helped me cancel all buzzing , noise without any drop with music ( primarily bass ) quality

Worked for a week and then audio was distorted. I thought it was my CarPlay screen and I bought another one. Turns out it was this expensive piece of junk. Guess I will try the $10 ones.

Connected from computer to sound bar, made background noise already present 10x worse than just an aux cable. Also lost sound from one of the sound bar speakers when connected to the noise isolator.Will be promptly returning.I will say though the build quality of the isolator seemed top quality 👌 i'll be it from the outside, aluminum used for the casing and decent braided aux cord came with in the packaging.

Didn’t stop the background noise but no change to the sound

This unit is 3 to 4 times more expensive than the other ones, which I also bought and tested in a Nissan Sentra. I used this in-line with the AUX cable for an aftermarket CarPlay unit. All of them eliminated the hum and buzz noise, but the difference is the resulting sound quality. The cheaper units filtered out much of the "richness" of music and made the music sound as if it was in Mono and dropped to volume to 40-50 percent. This unit also loses some richness and volume, but significantly less so than the cheaper units, so until I find a better one, this one is the best option on Amazon right now.
