"Not Your Average Headset"4.0 starson by pnwmermaid
Pros: The music playback is excellent. I have been using Sennheiser portable headphones with noise-cancelling for many years. While these are not quite as good (not an over-the-ear design) they are still excellent.
Cons: I have small ears and keeping any headphone which anchors itself on the ear has always been difficult for me. These were better than most, but still gave me a little trouble. Most people probably won't have this problem.
Summary: Recommend because of the excellent sound quality.
