ipod headphone amp

i was considering buying some high-end sennheiser headphones, but they had 64 ohms and up of impedance. the ipod isn't loud enough to drive that. this is kinda bulky, but it's almost the perfect solution: a headphone amp that clips onto the ipod, has 16 hours battery life, and a li-ion battery that recharges over usb. and looks great, too. macmall has them for US$140. definitely on the christmas list.
