Review on 🔇 Compact Ground Loop Isolator - 3.5mm / 1/8'' Female Stereo Audio Input/Output, Compatible Model, Engine Noise Eliminator, Portable Design, Ideal for Same Audio Players - Pyle PLGI35T+SEO by Johnathan Stoner

I got this to reduce electrical noise for the secondary auxiliary connector in my car. It definitely reduces noise significantly, but I was expecting more reduction. Build quality is pretty cheap, but Pyle is a budget brand so I wasn't expecting too much. My biggest problem has to do with the size of the connector. The plastic part of the connector is quite wide, making it difficult to connect to my phone in a case. I'm a little worried about damage to the headphone jack. However, it is cheap and serves its purpose.
