If you're looking for quality over quantity (meaning good quality without the pricetag to go with it) I suggest the Shure E2c earphones. I have no complaint about those, they run for around a $100 or less depending where you get it. I never really tried it running but I'm sure its good to go. I tried the ER6 Etymotic earphones while running and their "so so".
I run alot(cross contry) and im looking for a small but good sounding pair of headpohnes.
