Reason # 1 to not use stock apple earbuds : They make it look like you have an Ipod in your pocket.
Reason # 2 to not use stock apple earbuds : They sound like complete crap.
Yeah yeah I know we're talking about mp3's and that the iPod audio out isn't the highest quality sound wise. But I swear by old school, black, Walkman style headphones, they look non iPod like, and sound great. A decent pair of Sony's set you back $45, and last forever.
(FWIW, the headphones that came with the first couple of original Walkmans sounded like crap too..... )
