Review notes: My first impressions of the sound of the B&W P7 are based on direct comparisons to other headphones - the v-moda M100 and XS, the FAD Pandora VI and IV, the Beyerdynamic T1 and T90, the AKG K812 and K712, and notes that I've accumulated from many prior reviews. I'll describe how I relate to the P7 (i.e. my personal tastes and how I use the headphone) only after covering all of the objective issues. I reviewed the previous P7 that I purchased in October of 2013, but I purchased this headphone again (after trading off the previous P7) because I now use the Apple i-device Audioforge Equalizer app to make a more precise determination of where the weaknesses are in each headphone, and I wanted to make a curve for the P7 as part of my reevaluation. Although the maximum resolution I get from the i-devices is 44 khz (CD quality) using Apple-compatible DACs such as the v-moda Verza, that resolution is more than sufficient to determine a headphone's signature, which is its basic sound quality. I rarely need to go beyond basic sound quality unless the headphone is criticized elsewhere for tonality problems or unusual distortions, etc. In the P7's case, I don't find anything that I see a need to report, for example why the deep bass may have less detail than a few other headphones in this general price range. I find it acceptable, so I'll just report the common issues and then go on to the physical description. The P7's deep bass (see 'Kellogg Auditorium' below) isn't quite as detailed as I heard with the FAD Pandora VI or the MrSpeakers Alpha Dog, or even to a lesser extent with the B&W P5 Series 2, but it sounds good - i.e. there's good weight and impact for any music genres I listen to including EDM, and enough detail when the bass has good detail to appreciate it. The most common problems I have with headphone bass are weakness, muddiness, bloat, narrow humps - none of which are a problem with the P7 in my tests. I can't say how perfectly the bass blends into the midrange, but it sounds pretty good. The mids between approximately 300 and 400 hz are recessed somewhat, making voices seem a little distant. The mid treble between approximately 3500 and 6000 hz is also recessed a bit, but the fooler for a lot of users who try the P7 for the first time is the emphasis around 9000 hz, which provides extra brightness in that area to offset the perceptions of reduced 'presence' in the mid treble. If I could offer a visual analogy of the P7's overall sound, it would be like looking out of a normal house window that's clear and unobstructed with the equalizer ON, and looking out of a window that's the same width but only a couple of inches high with the equalizer OFF. That's an exaggeration of course, but the recesses I mentioned constrict the audio image to some extent - it's a dramatic difference when listening in a very quiet environment and making that direct comparison, but not so obvious when just listening to music and not making comparisons. In spite of the fact that I rated the P5 slightly better for detail in the deep bass example above, I find the P7 to have a more hi-fi sound overall, because it's smoother, and more extended on each end. In my opinion the P7 is not one of those headphones that has to be EQ'd or modified in some way for hi-fi listening - it's a full-fidelity headphone with only the minor flaws that I noted here for the record. The P7's isolation is much better than average for a passive-isolating closed headphone, and the leakage is very low, so the P7 should be good for use in offices, libraries, or on public transit, even at audiophile volume levels. The P7's weight feels light for a full-size circumaural (around-ear) headphone, and thanks to the relatively light weight and how it's distributed by the headband and earpads, it feels comfortable enough for extended use. The underside of the headband isn't exactly soft and squishy, so for users who are bothered by even moderate headband pressure, I'd suggest moving the earcups down an extra 1/4 inch to carry more of that weight/pressure with the earpads. There are a few headphones I've purchased recently that have very soft and squishy earpads - the Beyer T51p, the Sennheiser HD26 Pro, a few others..., but the P7 earpads are a little stiffer than those, and the clamping force is fairly strong. In spite of that I don't experience any discomfort with this headphone. Headphones with a stronger clamping force and/or earpads that aren't comfortable include the Sennheiser HD280 Pro and the Marshall Major. Other headphones with less clamping force and softer earpads are the Beyer T51p and the Bose QC25 (especially the QC25), but the design of the P7 must certainly be necessary to maintain its bass response, and I don't know but what Bose might be using some type of electronic DSP to produce its bass response. The P7 is an ideal portable headphone in that it can be pulled off the head when not in use and worn around the neck with no discomfort. This is important to me since even though the P7 does come with a carry case, I don't like to have to carry the case with me outdoors. The range of adjustment is good - 1.375 inches on each side, where my average size head fits in the middle of that range. The cable is single-entry and detachable internally, and has a center button** for stop/start and previous/next, and buttons for volume up/down, for Apple i-devices at least. **The P7 includes a second generic cable without controls. In previous reviews I've included the following music examples with comments about how the headphones sound with each track. My suggestion is instead of reading each one as an absolute unto itself, you could compare my notes here to those other reviews and see how the P7 compares with each individual track.
