No problem L0SLobos,
Yes, I've listened to the B&W P3s also. I really like the P3s, but I much prefer the sound of the BeoPlay H2s. I'd say the P3s are a very impressive sound for the money with a decent mid-range, but I just find them a little dull and unexciting, lacking a little in detail overall. I find he H2s to be a much punchier sound with plenty of low-end without sacrificing detail - overall a good warm presentation, but unrestrained in their delivery. I'd definitely say they're closer to the P5s, though I've yet to hear the P5 S2s, but I imagine they're not far off - they certainly don't have the detail of my P7s, but are much easier to drive and much more comfortable to wear for longer periods judging by their weight.
Albeit, aesthetically the B&W design definitely takes the crown - I'm quite surprised at the reserved design for a B&O product actually - the P3s are much more desirable and look a whole lot more luxurious. I prefer the sound of the H2s though. I suppose it could well be down to what you enjoy listening to, I imagine the P3s would be better for softer music, such as acoustic and easy listening, but the punchiness of the H2 lends itself better to rock/pop/electronica in my opinion.
It's a tough call, but I suppose it comes down to listening preferences and whether they are going to be a fashion accessory also.
Also, regarding the durability, I'm not sure where hunteragain is getting his information from, but all B&O headphones come with a 3-year warranty, which is longer than any other headphone manufacturer I know about, so I'd say that they're fairly confident that these things are built to last.
