Bowers & Wilkins P7 Wireless ($399)
Oh boy, I love it when a headphone ticks all the boxes and doesn't have a fatal flaw shiv strapped to its ankle ready to strike at an inopportune moment. Yep, the Bowers & Wilkins P7 Wireless is a dandy daily driver for all your mobile headphone needs.

Ever lust for an ambling bimble through the countryside on a bluebird day with perforated lambskin driving gloves grasping the wood and chrome steering wheel of a vintage English sports car? If you even…

Sound Quality
The B&W P7 has a gentle, tasty "V" shaped response with a slightly emphasized mid-bass and mid-treble. To my ears the only thing that rises to the level of a flaw is the bass boost is a bit mid-bass centric, and bleeds just slightly into the midrange. This is a very minor flaw and easily accommodated in listening.

Other deviations from neutral are minor and don't rise to the level of "flaw" but rather add to the character of the headphone. Me, I'm a "give me neutral with a slight roll-off in the upper treble and a 5dB bass boost below 150Hz" kind of guy, so…

Measurements Wireless

Unless otherwise noted I will be discussing the measurements of the P7 in wired mode.

Raw frequency response plots show a headphone quite near the Harman Target. Bass boost amount at about 5dB over the minima at 400Hz is appropriate, but the broad emphasized hump reduces bass extension and bleeds slightly into the mid-range. I would characterize this as a minor flaw; not bothersome but…

JBL Everest Elite 700 (MSRP $299; Street ~$224)
Sean Olive and his crew of researchers have been at it for a while now, and I reckon some their work should have trickled down into JBL products by now. One likely candidate is their recently released JBL Everest Elite 700, a wireless, noise canceling, over-ear headphone, which contain Harman's whiz-bang TruNote technology that is claimed to calibrate the headphone to the wearers ears. Let's check it out.

Sound Quality
Generally speaking, the JBL Everest Elite is a fairly good sounding, neutral balanced headphone...for a noise canceler...at this price.

When wired and unpowered, I found it to be somewhat upper-mid forward and a bit hard sounding. Somewhat "cupped hands" and shouty right in the middle of the female vocal range. Also, mid-treble range is somewhat de-emphasized. This is good because this area can be quite annoying if over emphasized, but when missing leads to a lack of nuanced resolve. Cymbals are relatively normal sounding, they're just missing some of their…

Measurements Wired Active

Measurements Wireless Active

Raw frequency response plots of the wired passive mode show respons between 400Hz and 2kHz somewhat above target response giving this headphone an emphasized and forward upper half of the midrange. Bass response is fairly on-target and punchy sounding, but is a bit overwhelmed by the midrange…

Audio Technica ATH-A2000Z ($649)
I've got to admit I'm not a big fan of the Audio Technica line of headphones with the 3D Wing Support System headband. My previous experience is that they tend to be far too bright and lacking bass response for me, and the headband just never fits right; I've found it very difficult to get a seal. I've also had horrendous problems getting them to seal properly on my measurement head. Well, something must have changed because the A2000Z fit's my head, and my measurement head, quite well...and…

Measurements

Raw frequency response plots show a headphone quite close to the Harman target from about 40Hz all the way up to 2kHz. Remarkable! Unfortunately, above 2kHz, things begin to go awry. The peak at 4kHz is somewhat high, which I felt gave them a sharpish character tonally. The drop after 4kHz is probably a good thing to steer energy away from the piercing 5-8kHz area, but response 5kHz and above is a ragged mess. This clearly makes its appearance in the 300Hz square wave and impulse response.

Beyerdynamic T 51 i ($299) and T 51 p ($289)
Quite a few years ago now I reviewed the Beyerdynamic DT 1350 ($289) quite positively. This headphone is sold into Beyer's pro audio distribution channel, primarily to DJs. Subsequently, Beyer produced a T 50 p to sell into their consumer channel that looked quite similar, but didn't have the split headband. It didn't sound nearly as good, either...I was bummed. Then, a couple of years ago, Beyer updated the model to produce the T 51 i, which I heard at a show and thought sounded quite a bit…
