I'm not really an audiophile, but I do enjoy great sound fidelity.This player offers many great features and the user interface is decent (not as intuitive as the other better players out on the market). I can't really complain about those two things. It's got so many features that I thought $180 for the player was a steal.My only complaint (and a big one at that) is the sound quality this player transmits. I use Shure E4C earphones, and they definitely expose a bad source. The sound on this player compared to the iAudio X5L that I sold doesn't even compare (i've tried the iriver clix too, and that thing also sounds way better). The sound is very flat and muffled to my ears, it lacks any aggressiveness or warmth that i've been accustomed to. Bass response is also very muffled.
