I bought the P5 Series 2 at the Apple Store - it was one of the safest buys I've made, since the B&W quality and decent sound are always a safe bet, even at the premium price. It might not actually sound as good as the original P5 (don't know), but I haven't had the original for more than a year now, so I can't compare them directly. I can say that this P5 looks and feels great, fits well, is secure on my head, is comfortable, sounds OK, and I'm not disappointed.
