Hmm… I’m slightly surprised about the comments/reviews about the B&W P7
I have one and I have heard quite a view Headphones ranging from Sennheiser via Grato and Ultrazone to Beyerdynamic from Entry to HighEnd Models. And from my PoV the P7 is the Best in the sub 500,- class and punches also above this level.
What I like:
Treble - very, very good (probably the best in the up to 1000,- class)
Soundstage - Very accurate. Its easy to locate the exact poison of on instrument, voice and/or noise. (You’re right in the middle of the show…)
Very detailed from up-mids. Its just crisp!
Bass - really good at reproducing Moog Taurus type of bass (grumbling along, from deep down)
Works really well with extreme left-right panning
Very fast response
Materials and Comfort. Up there with the best
What I don’t like
Lower Mids to Mid-Bass - can get lost and muddy
Not Airy (Ok, its closed can and has its disadvantages)
Not Neutral, U/V shaped
A tad to small
Used with Music:
I hear a very wide range of music from Rock, POP Metal to Jazz, Alternative & Classic. However, I listen most to Genesis, Pink Floyd and Dreamtheater but also stuff like Agnes Obel, SADE, Norah Jones, Feist, Melody Gardot, Massive Attack……..
So, I would say its works very well with stuff like above but also with any acoustic /instrumental stuff.
May not the best choice for modern POP, RNB etc.
The Bass is sometimes described as boomy, but the B&W P7 needs to burn in very well (20-40hrs) in order to shine. Personally, I would say that straight out off the box the P7 is harsh.
Used with gear:
iPhone or iPad? Works, but a bad Idea as this one scales very very well and needs a good source (not just power but „clear“ as well well) to show, i.e. Meridian Explorer/Prime
A really great one, which was made for mobile use but is best used at home with a good AMP/DAC. The 400,- EUR price tag is more like bargain and remember this is a closed can. The P7 has its weakness, but its strength are very hard to beat (esp. treble, crispness, locating characteristic/soundstage).
All in all lets the watch what B&W would be cable of with a „open-can P9“ if the P7 is just the beginning.
Opponents? From my experience the likes of Sennheiser HD600/650
Next Level Up? Skip and go straight to Audeze/HD800.
I never found the P7's treble to be harsh... The bass does tone down with burn in though IMO. There is also the entire thing about positioning and its influence on sound with the P7 as they are sensitive to sound changes with position changes.
