Posessing an iPhone was a challenge because there's seldom any headphones available with the click-mic option. It was a couple of years ago when I asked my parents to get me a pair of vmoda vibe duo ear buds. Headphons were great, only they had a crappy cable which broke after a month of use. This happened when I was on my way to Heathrow — going on holiday.
When I got back to UK, I've spent some time on the net and the vmoda's were getting the best ratings for the sound. I was disappointed about the £50 headphones giving in on me, so I've ripped the earbuds off their cables and soldered them onto the standard iphone cable. The buds still work now (two years on), I just buy a new set of standard headphones and replace the cable when it gets worn off.
And they sound great which is amazing for this type of headphones.
