There are people who use headphones?
try sitting in a cubicle and hearing all the annoying older people around try to discuss whats hip, their kids, menopause, music, ETC>
when designing....there is no better escape, then headphones..and some kick ass music.
the ones i have now kick ass. i cant hear a damn thing...and the music listening quality is pristine
i have looked into Sennhiesers, and will look more.
