Mountain Bike Earphones

Long lasting, Durable earphones?
Hello, I like to listen to music whilst I do activities such as mountain biking, skateboarding, snowboarding etc… needless to say my earphones never last very long, i’ve used ipod ones, skullcandy buds and various other cheap alternatives but they all stopped working pretty quickly, I can’t use headphones as I cannot wear these under a helmet when needed!
any ideas of earphones which will last a bit longer? which don’t pick up noise from movement.
The cheaper the better too!
(I am from the UK, so would rather a UK based company so i don’t have to spend ridiculous amounts on delivery)
There is a pair of cheap (2$) headphones available on dealextreme.com. i use them, they stay in your ears, and for me they last at least three months. They are also noise isolating.
