They both sound almost the same to me. Clip+ sounds about 2-3% warmer than the Fuze, and maybe just a tiny bit better. The Clip+ seems like it has slightly more accurate volume control, and that probably has something to do with it. Both are on normal/flat EQ with RE0's (non-foam modded).
I like the FM radio better on the Fuze. My Clip+ doesn't work on 95.9 and 96.1. It's silence. No static, or anything. Can anyone else with a Clip+ check on this and see if theirs does the same thing?
@ the OP: The Fuze and Clip+ are pretty cheap. You could get one of each, and spend about $100 if you've got the money and are curious enough. Try them both, return one, and use that money for a micro SD card. Just a thought.
