Youtube review: http://youtu.be/_L2naYeonHQ Sources: iPhone5 alone, iPhone5 with FiiO E07k using LOD, iPhone5 with v-moda Verza DAC/amp, various computers using the v-moda Verza DAC/amp. First impressions of the B&W P7: Average soundstage for a closed headphone, which is actually good since the recording makes a much bigger difference than the headphone.The overall signature is what I would describe as slightly dark, influenced mainly by the midrange. The B&O H6 for example has a lighter than average sound, so the P7 is a perfect alternative to the H6. The P7 has an excellent treble - lots of detail and harmonic extension, but no tendency for harshness or sibilants. The bass of the P7 is strong low down, up through the mid-bass, but the upper bass is not inflated, so the wide variety of music genres that I play have a decent amount of warmth and impact without getting muddy or overly boomy. I'm aware that burn-in with headphones is a controversial subject, but I would strongly recommend giving the P7 at least 12 hours of burn-in with fairly loud music before making a final judgement of the sound. Most headphones that I've tested and used sound better with real headphone amps and DACs than with just an iPod or iPhone, but other than an obvious improvement in soundstage and a better sense of "air" around the voices and instruments, the signature doesn't change that much with most headphones when switching from the i-device alone to the various amps. The P7 is one of those headphones where it makes a big difference. With the i-device alone, the sound is darker and the bass is looser or more boomy. With a computer running the HRT Microstreamer DAC plus headphone amp, the bass becomes much tighter and the upper range smoother. I can't be sure why there's such a difference, or that my experience will carry over to anyone else's gear, but there it is. After a few days with the P7, I'm enjoying the sound immensely, and I even ran several test tone sweeps - not to evaluate the results in a vaccuum, but to compare the results with other top-quality headphones I'm familiar with. The bass is smooth from the bottom (~20 hz) to top, on up through the mids into the lower treble. I found the area around 1.5 to 2 khz slightly elevated (~2 db or less), 3 khz slightly recessed (2 db possibly), 4 to 8 khz fairly even, and 9 khz slightly elevated (~2 db). The amplitudes are just guesses, but the relative deviations from theoretical flatness should hold up unless the design were to change down the road. Comparing to the v-moda M100, if I take the M100 and use iTunes Bass Reducer EQ with it (but no EQ with the P7), the M100 then would sound very similar to the P7 except that the M100's mids are more forward. The P7's mids are ideal in my judgement. Isolation with the P7 is average or better for a good closed-back headphone and leakage is very low. The leakage is so low in my tests that users should be able to play the P7 at medium-loud volumes in quiet offices without bothering other workers who are close by. The P7's physical design is one of the most perfect that I've ever encountered. The black colors over brushed aluminum are elegant, and the "headphone bulge" while wearing the P7 oudoors is inoffensive - it doesn't make me look like an astronaut or robo-cop. Instead of designing the earcups to fold flat like some headphones, the P7 is designed so that the cups fold in on top of each other into the headband area. The P7 is an ideal portable headphone in my view, since the earcups can be pulled down and the headphone worn around the neck all day when not being used, with perfect comfort. The P7 earcups completely enclose my ears without pinching, making it very comfortable for hours of listening. The P7 that I bought from the Apple Store comes with two 4-foot cables - one with a generic plug and no controls, and one with the Apple-style miniplug and standard Apple controls (volume up/down and start/stop). The literature says that the P7 cable has a microphone, but I don't see where it's located. The cables are single-sided and much thicker than the P5's cables, thankfully. The earpads are the standard B&W removable type with magnetic fasteners. The carry case is neither the hard type nor the useless cloth bag that some manufacturers issue - it looks usable in luggage or backpacks since the headphone is folded inward on itself, providing additional protection. A 3.5 mm to 6.5 mm adapter plug is also provided. The music tracks below were listed in only one prior review (B&O H6 Green), and are a random sample selected from the 400 most recent tracks I've acquired. Since these tracks cover a wide range of genres, and were selected when I was using several different headphones, there won't be a bias toward the P7 headphone with this music. My suggestion is instead of reading each comment below as an absolute unto itself, you could compare these notes to the prior (H6) review and other reviews as they get posted, and see how the P7 compares with each individual track.
