I use
these. Can't complain for the money but the wiring is pretty fragile so you have to be careful with them. I've killed off a few pairs being heavy handed before realizing what was happening (now I'm much more careful putting them on/off.) This type of earphone tends to pick up wind noise so they're going to work best with something like Cat Ears, Wind-Blox or Slipstreamz Spoilers.
