Query: Terrible sound quality with iPhone

I installed this product for use with my iPhone and it failed to perform up to standards on the first try. When using it to listen to audio, the music would "skip" at least every minute or two and sometimes skip for up to 30 seconds continuously. The phone quality was very poor; I could hear the other person just fine, but they complained of lots of background noise (there was no echo, so it wasn't a placement problem). Installation and set-up were easy, and it was convenient and easy to use, but the audio quality was intolerable, so I would not recommend this product.
