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!"
I was asked to run the sound for this show yesterday, but I hav to work another show for Carquest Friday night. We were just discussing how many lumens the projectors would have to be to fill a 50' screen and actually be bright enought to see. We were thinking 50k or so. I'm going to look up the specs of these christies to see what they are.
