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!"
If that's the definition then maybe the latency is 2.083 ms from Off to On and then 2.083 to go back to Off again, or 2.083ms x 2 = 4.166 ms
Maybe the 480Hz is OK since the 2.083ms is within that range of turning a "pixel" On.
