While you won't find us dropping our wad on their new $480 head-mounted, speakers anytime soon, Sony might just tempt us with these. Their SRS-ZX1 speakers feature what Sony calls a new "Mobius Duct" meant to bring a decent, low-frequency response in a relatively portable 3.1 × 6.6 × 7.4-inch package. So it's small, just not that small. This active speaker system with built-in amp gives 20W x 2ch output off 2x analog inputs. Available October 20th in Japan for ¥49,350 or about $426.
