Earphones / Headphones: Where to try, what to buy?

Looking to go out and get some new headphones tomorrow, preferably in ear (to replace iphone standard ones) and with mic/remote to control my phone and make calls. Budget is quite strict at £80.

Any suggestions?

Shure SE215. Myself and the missus both have them, they're bombproof, and sound amazing.They have a detachable cord, just after the two sides come together, so you could get a 3rd party iphone remote thingy.
