I agree about the skull candy earbuds.
They have different sized rubber ends, and they stay in your ear really well.
I have a couple pairs and use them while riding my bicycle and motorcycle.
Great sound, and pretty cheap.
Skullcandys are definitly worth the money. I have a pair of their "titan" metal ear buds and they're the best headphones I've ever owned, and they work as a headset with my blackberry too (even though they don't have a built in mic). I'm actually looking into getting a pair of "full metal jacket" ear buds, because I give my headphones ALOT of abuse and could really make good use of the steel braided cord.
I use to have the Skullcandy FMJ in which I got for $65...I now have the iLuv iep311 in which i got for $12.99!!!! Ahhh i was an idiot for getting the Skullcandy...move into the future and save that $$$ y'all...Price/Precision/Quality
