It kind of worked in the first two months, with the hissing sound. However, I was able to deal with it. Then after the two months it started to get worse, louder hissing sounds. But, I was able to still use it with this annoyance. Now, it just doesn't work even with adjusting the wire. It's a piece of garbage and the music won't even come through the car speakers anymore. I wish I had returned it in the first month! Don't buy this!
