Skullcandy, the company that pretty much invented snowboard-specific headphones, have hit us up to announce their latest collaboration with Terje Haakonsen – the man who pretty much invented modern freestyle riding. The second Terje Haakonsen signature headphone will feature the great man’s classic viking sword and helmet design spattered over a pair of Skullcandy agent phones. The symbols have been given a bit of an update by Skullcandy’s in-house artist Brandon Christenson, and overall, we reckon the end result looks pretty sick. But you can see them below and judge for yourselves…
