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!"
The Verizon Touch Pro has the same CPU as the standard Touch Pro. There was a false rumor a while back that Verizon was using going to use a slower CPU. Of course the memory on the phone is less that non VZW Touch Pro's. And GPS for older phones requires a firmware update to enable it without Verizon's shitty software.
(And as for why it costs more, well that's Verizon's way of making money. Since they have a solid network they aren't worried about subsidizing the phones as heavily. )
