It works like a charm and it works so well I forget it's even there. I have a Samsung Galaxy S21 Ultra that only has a USB-C port, so I use a splitter adapter to charge it and listen to music in my truck at the same time. This causes a ground loop that results in a BIG hiss when I'm trying to enjoy the music. However, this little device solves the problem and I can listen to music and there is no hissing anywhere!
