Just to point out, the QC15 cannot re-charge - they consume AAA batteries; the QC3 is the rechargable (and on-ear) model. The QC15 gets the nod if you want to go with Bose headphones though.
Regarding more thoughts:
I agree with the "lack of emotion" criticism of the QC15 - they're fairly polite and well mannered, no clash-trash top-end, no mud down low; they don't really do anything "wrong." However they don't really do anything "right" either - they're kind of ho-hum and soul-less at the end of the day. I think for what the ANC is, and the other compromises associated with picking them (comfort, mobility, etc) that flaw can probably be overlooked in given contexts, but there are probably better alternatives otherwise (especially if you don't need the ANC, which can cut some bucks off the top and keep you from buying batteries so often).
I haven't heard the V-MODA.
The B&W P5 are a fairly good on-ear headphone, but don't offer the isolation of the QC15 and (imo) get a little warm on the ears. Otherwise they're comfortable, and sound good enough. The aesthetics are certainly not for everyone.
Now, I know you said "you shall not consider" other models, but I'm going to suggest them anyways, because I think you're potentially looking in the wrong direction (either in terms of how much you're setting out to spend, or other paradigms). First, I would STRONGLY suggest you take a look at in-ears - they are substantially better for what you'd like to do, as they will get you better noise isolation than any on-ear/around-ear headphone (depending on model - I'd suggest Etymotic), and are much easier to lug around with you (even with the carrying case, the QC15 are an ordeal, not to mention that both the QC15 and P5 just scream "mug me"). The other model I'd like to suggest is a non-ANC closed-back set from Sennheiser, the HD380Pro. They cost about half of the P5 or QC15, offer at least as good isolation as the P5, and sound pretty good if I say so myself (the angled drivers do help this a lot methinks). They aren't as soul-less as the QC15, and seem less colored than the P5, but are still a good listen nonetheless.
If i had to decide between the P5 and QC15, I'd basically weigh isolation versus sound quality. The P5 get the nod for SQ imho, the QC15 take isolation. But the HD380Pro (at half the price), and various Etymotic, Denon, Monster, etc IEMs (at half to a third the price) will offer competitive isolation to the P5 (or better than the QC15 in the case of some of the Etymotics), be easier to carry around (the IEMs), etc.

This a common criticism of non-bright/aggressive headphones when compared to some of the real burners out there. DT880s are *far* from flat. I'm not saying you're wrong, just that it is very likely that you have habituated to a very upward-tilted presentation and headphones that don't provide that sound foreign or unnatural.Edited by obobskivich - 8/25/12 at 7:36am
