In-ear, on-ear or earbuds? I've seen the Sennheiser in-ear isolationg ones I use for travel at under $20 all over the web. CX-300 I think. I don't like those for walking the dogs because they block too much noise. I picked up a few pairs of Blackberry headests from Meritline. The pause/skip button inline is great to have - along with the ability to use as a phone headset, and I think I paid $1.99 a pair on one of their daily deals. $4 shipped still not bad.
