Thank you Apple. In a day of throw away electronics and the lowering of audio quality, you come and make the crappy sounding mp3 (or aac) sound decent. Whitlock-good choice, they make the best headphones in the world. My advice to anyone who loves listening to music is to keep mp3 a portable media and never use it when you have access to CDs or LPs. Your ears will thank you for it. -maestro
