I've been using a pair of Creative EP-640 (not 630) IEMs with a Zune 120 and a Sansa Clip+, and feel that its time the Zune got it's own head gear.
I've been looking at the Phonak PFE 012 Perfect Bass. I believe they would be ideal for me, since I always considered the Zune a little lacking in bass, but I would also like forum's opinion on how they would compare with the EP-640 (I have been unable to find any comparison since they're two completely different beasts).
