Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
This thing may suck as a touchpad, but it can be very useful on other kind of stuff.
I have something similar for my robot to detect the surface under it. (and other uses that Im not gonna give my idea out for free.)
And this is just a weekend project, I make craps in my bedroom every weekend and I think I've learnt more than those people with a higher GPA. (They came to me for advices on their senior projects.)
Since it is not a product, I dont see this is a shame.
