Monoprice has well-received and very inexpensive sets.
I tried a pair of monoprice super-cheap earbuds recently because a web site said they were good, and it turns out they were terrible-sounding compared to those Sony Fontopias. I think best results are obtained when one spends more than ten bucks on one's earbuds.

Eh, I guess this one got a good pair, because they sounded good to me.
This one also listens to more podcasts than music these days, and there aren't many headphones that can't handle those.
