Depends what you're plugging them into. Koss ksc35 are by fat the best headphones I've heard that go that cheap. Very big-sounding, decent refinement, and the bass doesn't drown everything out. I only really use em with my discman. You may have to pay $40 or $50 for em as they're out of production, but it'll be worth it. An IGrado may be another good choice. Some people at head-fi.org would be able to recommend other stuff.
If you really want to hear something special(but expensive), see if your local hi-fi store has a Grado RS-1 headphone and the RA-1 amp(or some better headphone amp). Then plug em into a decent cd player, like a Rotel or an Arcam. Grado HF2 might be a little better of a Metal headphone for cds, but they aren't in production.
