Does anyone know of a decent set of wireless headphones to use with an iPhone 3GS? It's to wear whilst out on the road bike (cue road safety arguments *yawn* ), I don't need amazing sound quality but they have to be able to cope with a bit of sweat, be able to fit when wearing a helmet and cope with the vibration/bouncing about over potholes etc. Also need to have a mic so I can answer calls relatively quickly if needs be (only the odd emergency call-out for work rather than having a social chat…).

These looked ideal but the reviews aren't good, I don't want the sound breaking up all the time http://store.apple.com/uk/product/TY014ZM/A?fnode=MTY1NDA1MA&mco=MTM4ODE2MDk

So then these looked interesting but other reviews say they fail if you you get sweat in them as the PCB on the switches is unsealed http://store.apple.com/uk/product/TW687ZM/A?fnode=MTY1NDA1MA&mco=MTM1MjEwOTM

Ihave Sony HBH-200 from my previous phone. Works fine with iPhone. Haven't tried for calls, just music. About £20 new off eBay. Have used on bike and jogging no probs.

I've got the backbeats. I've found them comfortable and reliable so far. I use them on and off road, including in the rain. Great for answering calls on the move too. I did find that they cut out when I looked right with my phone in the middle back pocket, but moving it to the left pocket cured the problem. I'd certainly recommend them.
