Our take on the Bowers & Wilkins P9 Signature

I'm glad I got the chance to spend a few months with the Bowers & Wilkins P9 Signature headphones. As impressive as they are out of the box, they sound better and better the more I listen. It's kind of fitting — you could say these headphones have been 50 years in the making.

I'm glad I got the chance to spend a few months with the Bowers & Wilkins P9 Signature headphones. As impressive as they are out of the box, they sound better and better the more I listen. It's kind of fitting — you could say these headphones have been 50 years in the making.

B&W — the storied British sound experts — recently celebrated their 50th anniversary, and they created these headphones to mark the milestone. They've utilized the same design and engineering experience that landed their famous speakers in recording studios like Abbey Road.

Nicely built from luxury materials 

These headphones look and feel like a tricked-out version of B&W's other P-series headphones. The distinct square earcups are bigger than ever. The oversized plush earpads are butter-soft. And the sturdy, firm-fitting aluminum frame is beautifully covered in Italian Saffiano leather.

Sound profile modeled after B&W's flagship speakers 

Regarding the sound, B&W had the loftiest of ambitions — the P9s are designed to emulate their super high-end 800 D3 loudspeakers.To achieve this goal, they've angled the large drivers so that they hit your ear the way stereo speakers would. Suspended piston diaphragms deliver punchy sound. And those supersized earcups create a wide open chamber for air to move around in, resulting in clean, natural sound.

A truly enjoyable listening experience

Like a pair of top-shelf speakers, these headphones benefit from a nice break-in period. I expected the novelty of "living the good life" would wear off, but they felt more relaxed the more I wore them. And the sound seemed to spread out, even as the strong bass tightened — especially noticeable when paired with a headphone amp/DAC.

I mainly listen on my laptop through an AudioQuest DragonFly Black v1.5. But these versatile headphones sound great plugged into my phone, too. One of the three included cables offers an inline mic for calls and music.

Throughout Jack White's Acoustic Recordings 1998-2016, instruments were well-defined and placed within a three-dimensional sound stage. These 'phones manage to reveal the upper registers of banjo and harp plucks without ever sounding harsh. Also striking was the complex sub-bass that fueled the production of the new Tribe Called Quest album We got it from here...Thank you 4 your service. Samples sounded distinct, yet they were still expertly mixed together with the drum claps and vocals — all surrounding my head.

Bowers & Wilkins P9 Signature

James G. from Marina Dl Rey, CA on 12/14/2018

Crutchfield Customer Review (What's this?)

The sound is what I like about these earphones. It is wide range and has a perfect mellow, never tiring enjoyable sound. Bring a whole new life to things that would sound irritating with most other earphones. The P9s make make music sound spectacular. Take for instance the band Vietnam and their two albums "An A.merican D.ream" and "Vietnam", These sound like what an era should have sounded like on the P9 when combined with a good DAC and headphone amplifier like the Arcade Dac II/

Pros: Always perfect sound no matter what type of music.

Cons: The short cable could have a plug at the end that has a tighter fit. It can pull sideways and create static. I feel it will not last long and need replacing. The long cord is far better quality and does not have this problem.

This is a great sounding head set. Very comfortable.

Pros: Great sounds. I hear things I have never heard before. Sounds best if you use a HD Walkman. Very comfortable.

Cons: None I can think of.

p9 vs p7

Billy from Juneau, AK on 4/9/2017

I have these and the wireless p7, like these for pop & country but for jazz & classical, I go to the p9. I'm comparing these wired, no comparison to be made wirelessly. I use the p7 for wireless solely. The p7 are happy with a couple of clicks on the volume, The p9 take 4 clicks to bring them into full performance mode. But once you do, they have a broadness and depth that the p7 just doesn't have. But for walking around and being untethered, their the obvious choice. If you like brightness the p7's really shine. The p9 is more of a computer headphone, lot less versatile then the p7.

Pros: wireless, good wired too, quality sound, short of esoteric

Cons: I'm content, no cons for me, but a dac would be pretty useless on these.which can be a neg or pos depending on your desires

Crutchfield customer from Sacramento, CA on 1/15/2017

Crutchfield Customer Review (What's this?)

I had high hopes, high expectations for the P9. And for the price, that's not unreasonable. As for picking up fine details in recordings, they're heard, but dimly. It does a pretty good job of separating several different instruments at the same time. It helped me hear parts of recordings I hadn't heard before. I feel it does a good job with excellent-recorded cds, but I was displeased with too many cds. I felt like with some female vocalists and David gates, an equalizer perhaps was needed. Having spent good money for these headphones, that's unacceptable. There probably are too many cds out there that are not pristine in their sonics. I say to Headphone makers:"That's the music world that we live in. Deal with it. Solve it." I feel I could have found several less expensive headphones that I would have been just as happy(unhappy) with.



The best I've heard.

Fred from Cupertino, CA on 12/9/2016

Crutchfield Customer Review (What's this?)

I had been auditioning various headphones for about 3 weeks before getting to these. Most of the 6 or so I had auditioned were acceptable but all had something objectionable that blew them out of contention (comfort, sound compromises, price). All of them were less costly than the P9, ranging from $250 to $700. Surprisingly the best sound I heard was from the cheapest pair, but they were extremely uncomfortable for me. So I kicked up the price ceiling with skepticism since I had just been reminded that higher price did not necessarily equate to a more satisfying product. Well, I'm glad I did. The P9's didn't blow me away at first. They aren't designed to do that at all. However, they have proven to be the most revealing transducers of any kind that I have experienced. Low level detail, spatial depth, width and volume (if they are present on the recording), vocal emotion especially, I could go on. For me it's all there. Add to that supreme comfort and quality and I have found what I was looking for.

Pros: Sound like music Wonderful feeling of space

Cons: Might be a little more extended on top? Maybe a tad less bass?

GREAT Soundstage and warm bass!!

Craig from Rochester, NY on 11/21/2016

Crutchfield Customer Review (What's this?)

GREAT sounding headphones. I wasn't a fan of B&W's previous headphone models, but the P-9 really shows off their skills. Wide open soundstage mixed with a generous amount of bass and rich highs makes these a real threat to listen with. Being in this business for 15 years, I can say that I do recommend these!!!!

Pros: Soundstage Bass Build Quality Cabling Midtones

Cons: Highs could sparkle more

Crutchfield Customer Review (What's this?)

The sound is great, but I have not been able to compare it to the best. They are very comfortable and look great.



Bowers & Wilkins P9 Signature

Guest from Forest Hill, MD on 10/12/2016

I love my P7s but these are in a league of their own. I use these with a iPhone paired with a Dragonfly Red and the sound is marvelous. I thought the P7s could use a little more kick in the low end and these provide that and so much more. They are the P7s on steroids. Well worth the hefty price tag.

Product Research


Overview: The Bowers & Wilkins (B&W) flagship P9 Signature over-ear headphones are crafted with the finest materials and acoustic engineering available. They were designed by B&W's Steyning Research Establishment in West Sussex, England to reflect 50 years of audio excellence. The P9 Signature comes with an Apple-compatible cable with an in-line remote and microphone, two additional cables, a 1/4" adapter, and a luxurious carrying case.

Engineering and Design: The P9 Signature features 40mm dynamic drivers with a nylon damped cone and an advanced suspension. The CCAW (copper-clad aluminum wire) voice coils have an external large pole magnet for accuracy and power handling. The drivers are placed forward in the ear cup and angled at 15° to give you a more natural listening experience. The stereo image is aligned in front of you instead of to the side. Using Finite Element Analysis, the ear cups contain sophisticated dual acoustic cabinets of aluminum and composite materials. This design enables the drivers to reproduce your music more accurately. The headband de-couples each ear cup to prevent vibrations from transmitting between the two. The P9 Signature's ear cups and headband are covered in fine Italian Saffiano leather by Scabrenta, with a unique cross-hatch stamped finish.

Carry Case: The ear cups are hinged so you can fold them for compact storage in the leather-trimmed Alcantara carry case. This soft padded material is 100% made in Italy, and will protect your headphones from scratches and dings.

Cables: The B&W P9 Signature headphones come with three tangle-resistant audio cables. One cable has an in-line 3-button remote and microphone, designed to be used with Apple's iPhone, iPad, and iPod touch. The other two cables lack the remote, and come in lengths of 53" and 16-1/2'. A 1/4" adapter is included for use with your home components that are equipped with a full-size headphone jack.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I am a B & W customer, having owned 2 pairs of their speakers. Their products are world reknowned and are some of the best products you can buy. Seeing these headphones, reading all the good reviews, the great features, great build quality, not to mention they are beautiful, it was an easy decision to buy B & W again. If they sound as good as the reviews, and YouTube videos say they are, I will be very happy. I look forward to many hours of beautiful relaxing music listening. [ Robert  Jun 04, 2017 ]
Sound made me melt [ Gary  Jan 12, 2017 ]
Brand and Crutchfield is the best electronics company I have dealt with. Absolutely the best! [ Stephanie  Nov 16, 2016 ]
I really wanted a Maserati, but I figure this is a reasonable and less expensive (but perhaps no less exorbitant) substitute. Also Crutchfield doesn't sell Maseratis. Now that I think about it, maybe I should have ordered those Pryma 'phones by Sonus Faber... more Italian. On the other hand, these have that Saffiani leather, so I should be good. Also B&W stuff tends to sound really good and be delivered with superb industrial design. [ William  Oct 19, 2016 ]
