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!"
That said, I noticed this story and wanted to leave a comment.
Regarding the custom printing and engraving, these options are actually provided with security in mind. Many of our government and enterprise customers request tracking/serial numbers engraved on the drives for internal tracking. This allows them to assign drives to certain individuals and keep track of them. We also engrave information such as “If found, please return to…” All very useful!
