You'll regret getting these, they'll be super heavy on your ear that has the controls, and, the thing that flips the lense will probably break in like 2 months.
I had a pair of those Oakley MP3 glasses since I run a lot, and, they were unbearably heavy, my ears started hurting after 20 min of wearing them. If you want some bitchin' glasses, cancel these and get some Spy+ Optics or Oakleys.
