To make a long story short, the V300 is somewhat boomy/bass bloated and has some kind of high-mid peakiness. The bass extension is poor and the treble suffers from some resonance and ringing in the very high registers.

Bottom line: These aren't the most accurate cans around, but they're comfortable, cheap and easy driven by most portable players. You can use on the go without fear of braking them or getting them stolen. Better options: Koss Porta-Pro, KSC series, Sony MDR-V6, Sennheiser PX100.
