Although the P3 doesn't score major points in the individual categories here, it's quite good overall for a portable headphone in my view. The highs are very recessed, which can be mostly corrected with a treble boost that doesn't result in excess sibilants or harshness. The corrected sound has a lower midrange emphasis, but no upper bass emphasis, and while satisfactory for portable listening, home listening requires a good DAC and headphone amp for high fidelity sound with good detail. In a direct comparison with the ATH M50 which is cheaper than the P3, the P3 does not compare well in any area - it sounds like a small lightweight headphone. I think the P3 with a treble boost can sound better in several respects than the P5, since the P5's limitations aren't as easily addressed, i.e. treble boost makes the P5 sound too bright and harsh, yet without it the highs are dull compared to the boosted P3 which sounds just right.
