I'm sure somebody has already compared these two players before, I just wanted to share what I found. I did a quick test and I noticed the bass on the Fuze is a lot better. It just seems nonexistent on the iphone 3GS when I compared it to the Fuze. The Fuze had tight bass compared to the iPhone, it had a fun thump. The iPhone's bass sounded like it blended in with the other sounds, and it just sounded like it was too weak to have a nice sounding impact. I used RE0s. I haven't done a test with my M50s yet, i'll do that soon when I'm bored. All tracks are in V0 LAME. The volume was the same, if not they were very close. The EQ is off on both players. These were the only tracks I listened to, i'll do more tracks later: August Burns Red- Truth of a liar Saltillo- A necessary end Saltillo- Backyard pond Radiohead- Idioteque Has anyone else had similar findings, what do y'all think when they're compared?
