It's not like we haven't seen MP3-playing headphones before
-- heck, we've even seen 'em from SkullCandy itself
-- but the latest pair from the aforementioned firm simplifies things quite a bit. Quietly showcased at CES, the Double Agent cans sport a built-in SD slot and the typical assortment of controls on one earcup in order to take the external DAP / PMP out of the equation entirely. 'Course, we wouldn't recommend this to those who aren't fond of just shuffling through their tracks, but if you're aiming to consolidate, you can get one step closer to doing just that when this ships in March / April for a currently undisclosed price.
