Query: Good sound, not entirely comfortable

These have surprisingly good sound for their price, but the hard plastic earclips are a bit difficult and uncomfortable. They've snapped off a couple of times, which really isn't much of a problem since they reattach easily, but if you get a good tight fit, your ears get sore after a while. They phones are an open design so they don't block any ambient sounds. Not bad if you spend time at airport gates and want to hear the flight announcements, but not great once you board the plane and want to block the engine sound.
