Review: Excellent Product that worked great for my application. - My situation may be a little bit unique but this Smof Ground Loop Noise Isolator is an absolute godsend. This completely eliminated all alternator noise I was getting through my car stereo. I own a 2005 Subaru Outback which didn't come with an aux in port and didn't have an easy way to add one. I considered replacing the stereo with an aftermarket unit until I found out the climate controls were integrated into the stereo and would cost a minimum of $250 just for aftermarket climate controls. I tried a few different FM modulators but struggled to find a station that consistently worked on my drive to and from work. As a last resort I found instructions online on how to hack my factory stereo and install my own aux port inline with the FM tuner. With nothing plugged into the port my FM radio plays; with a cable plugged in it plays from there. I spend a day modding the stereo and everything sounded fantastic while testing in my driveway. Later that day I started the car up and got my phone all hooked up only to be greeted by a horrible alternator whine screaming over my speakers every time I hit the gas. That is where the Smof Ground Loop Noise Isolator comes into play. I searched desertcart and based on the good reviews and price of the Smof I decided to give it a try. From the moment I plugged it in it has provided crystal clear audio. I now pair my phone to a bluetooth adapter which runs to the Smof then to my modded aux port. I have enjoyed hundreds of hours of audio books and music. The music playing from my phone through this setup provides significantly better audio quality than FM radio or CD. I could not be happier with this product and I'm so glad I decided to purchase it. Review: Works perfectly - Ever since starting to use an desertcart Alexa car device for hand-free phone calls, I've been putting up with a high-pitched whine from my car's speakers. The whine would go up in pitch when accelerating, drop when decelerating, and isn't present when using the radio. Digging around on the internet, I found that it's caused by ground loop noise; ground loop is created b/c the device has to be connected both to the Aux input and the "cigarette lighter" adapter for power in order to work, thereby double grounding it. Bought this device, plugged it into the aux port, plugged the Alexa's aux cord into the device, voila! no more pesky noise. ## Features - 【UPGRADED GROUND LOOP NOISE ISOLATOR】Say goodbye to annoying buzz and static in your speakers.
