Its like wearing school girls panties, attached to a home theatre on your ear. Minus the cum stains and the weight.
The best headphones site ever.

I like them a tad better than the k270s, because the bass is a bit drier, although it has some issues with ambience attenuation (hello vinyl hiss fuck of death).
