Very nice write up. I liked my P5 well enough to upgrade the cable.
i think the P5 S2 upgrades the sound of the original version while retaining the best qualities of the P5 S1, specifically comfort, isolation, style and portability.
Compared to the 1st version, the P5 S2 delivers better bass and a more rounded and refined soundstage.
I prefer this HP over the noise canceling HP's, if the sound is colored it works with rock and that works with me.
