Poor sound quality, volume adjustment broke after three weeks.

The good: Ergonomics, they definitely stay put for both cardio and strength training exercise.
1) Sound quality is sub-par on the highs and mids. Very muffled sound, and overly bass-y. They do block out a lot of noise at the gym with the volume set high enough. To the other reviewers that said the sound quality on these is good: If you have only used the included iPod/iPhone headphones previously, you will probably be impressed with the sound quality (the Apple iPod/iPhone headphones are garbage). However, if you routinely use another high quality headphone, such as a Klipsch or Bose, etc, you will definitely be disappointed with the sound quality on these.
2) The center control button (the one that will pause, play, forward, and reverse tracks) on the iPod/iPhone is difficult to use properly when working out. That is, one click is pause/play, three clicks is previous track, and two clicks is next track. If you are trying to go the the next or previous, you will most likely end up pausing/playing.
The bad: Volume rocker which controls the iPod/iPhone volume stopped working after three weeks. Returning them. Obviously, not durable to stand up to 15 or so workout sessions, even being stored in the included bag when not in use.
