We're still not sold on the merits of "5.1" sets of cans, but Psyko Audio Labs is looking to push doubters over the edge with its incredibly heinous 5.1 Directional Audio Headphones. Supposedly, the company uses a special alignment technology that delivers accurate surround sound to each ear "in a natural 3D sound field." In case you weren't skeptical enough, there's also a "subwoofer" in each ear cup, which sounds like a feat you'd truly have to hear to believe. Yeah, we guess the built-in amplifier -- which lets gamers "customize volume and bass levels" -- is pretty nifty, but for $299.99, they'd have to knock our equilibrium clean out of balance. Full release is after the break.
