"Depends on the player"4.0 starson by lovebears
Pros: Clear and warm high quality sound
Cons: Lack of consistent bass
Summary: Several reviews recommend the px100 above the px200. I tried both and the first one has more bass level but worse high and midtones. The px200 sounds awesome if your player is quite good. I got an old minidisc and I'm sure they would sound even better with an i-pod, iriver or rio.
Don't hesitate to buy them. You won't regret at all.
