This product works in that it allows me to bridge from my Tape deck adapter to my Iphone through a rubber protector sleeve. I can hear my podcasts fine. However, when I tried to play music I noticed that something was terribly wrong. The sound was muted and the music was clipped and very flat. I removed the adapter and went back to a straight connection to the Tape Deck adapter. The volume doubled and sounded like music again. Not sure how they messed this up but they did.
