About the Bowers & Wilkins PX Wireless

The first noise-canceling Bluetooth headphones from B&W

Bowers & Wilkins speakers have been world-renowned for over 50 years. So I'm not surprised at how quickly the British audio experts have made a name for themselves in the headphone world. They make some of the best-reviewed headphones we carry. The B&W PX wireless headphones are the company's first noise-cancellers, and maybe their most ambitious 'phones yet.
B&W PX Wireless headphones

The Bowers & Wilkins wireless headphones are built with high-grade materials and offer top-notch noise cancellation.

The first noise-canceling Bluetooth headphones from B&W

Bowers & Wilkins speakers have been world-renowned for over 50 years. So I'm not surprised at how quickly the British audio experts have made a name for themselves in the headphone world. They make some of the best-reviewed headphones we carry. The B&W PX wireless headphones are the company's first noise-cancellers, and maybe their most ambitious 'phones yet.

Packed with features, low on compromise

Consider everything these headphones can do. The PXs: (A) offer Bluetooth for playing music wirelessly, (B) include adaptive noise-canceling circuitry, and (C) still manage to preserve B&W's legendary reputation for performance. When all the noise and fuss around you disappear, you're left with pristine, powerful sound.  

Tough and attractive for the frequent traveler

On-the-go headphones usually land in one of two camps: durable or stylish. When B&W designed the PX 'phones, they figured out a way to accomplish both. Their aluminum frame makes them strong and light, yet sculpted and elegant. They look and feel smooth at every angle.

Here's a really nifty touch: the headphones will automatically pause your music when you remove or lift an earcup. Then they'll resume playing when you put them back on. That's really convenient if someone quickly needs your attention — like a flight attendant taking drink orders. 

Noise cancellation you can customize

These headphones boast a 22 hour battery life with noise cancellation, so they should last most trips — and certainly most commutes. And B&W's specially designed noise-canceling circuitry is super-flexible. Download the Bowers & Wilkins smartphone app, and you can choose the amount of noise cancellation based on your surroundings. 

The filters are named Flight, City, and Office. I put them to an extreme test.

Testing the B&W PX headphones here at headquarters

So this all sounds good on paper, but how does B&W's noise cancellation hold up in the real world? I tried it in one of the loudest, most chaotic places we have at Crutchfield HQ — the photo studio right before a catalog deadline.

Tunes from the '80s blared on the stereo. Photo props got dragged around and slammed into place. All the while, our art designers and photographers yelled back and forth, eager to get the right shot.

When I first put on the PX headphones, the noise-canceling circuitry hushed the room to a manageable murmur. Then I pushed play on a Spotify "Relaxation" playlist, and the only hectic part that remained, for me, was the flashing of the camera and the sight of people pacing back and forth.

In a peaceful place

I stood in the corner so I could stay out of the way. A bookshelf speaker, mounted about 16 inches above my head, pumped out tunes. While I could feel the woofer's pulse, I couldn't make out what was playing over my own music in the headphones.

I only realized how loud the speaker was playing when I lifted the right earcup, and the headphones automatically turned off. The loud chorus to "Love Stinks" by the J. Geils Band gave me a jolt. 

I was surprised how calm the quieting of external noise made me feel — even as everyone moved around frantically. I was under the same work deadline as each person in that room, yet somehow listening to the PX headphones removed the stress of the situation. They put me in a tranquil, above-the-fray mindset.

Product Research


Overview: The Bowers & Wilkins (B&W) PX wireless over-ear headphones feature classic styling and the latest technology and convenience features. They feature Bluetooth version 4.1 with aptX-HD for superior audio. The PX wireless headphones come with a 51" audio cable to use when you can't use Bluetooth, a USB-C charging/audio cable, and a quilted storage case with magnetic closures.

Bluetooth 4.1: The PX wireless headphones uses Bluetooth 4.1 with aptX-HD for high fidelity, 24-bit wireless streaming audio from your smartphone, tablet, or computer. SBC (Low Complexity Sub-band Coding) and AAC (Advanced Audio Coding) also assure high quality audio. The headphones support the following Bluetooth platforms: A2DP (v1.3), AVRCP (v1.6), HFP (v1.6), HSP (v1.2), GAP, SDAP, and DIP.

Adaptive Noise Cancelling (ANC): The B&W PX headphones offer Adaptive Noise Cancelling (ANC) to block out ambient sound so you can concentrate on your music. Four microphones (2 inside and 2 outside the earcups) are utilized for ANC. Using the Bowers & Wilkins Headphones App, you can select the Environmental Filter that suits your listening situation: Office, City, or Flight. The Voice Pass-Through feature lets you adjust the volume of sounds in the range of the human voice.

B&W Headphones App: The Bowers & Wilkins Headphones App is designed to optimize the use of the PX headphones with your smartphone or tablet. Opening the app on your device automatically makes pairing extremely easy. In addition to the Environmental Filter, the app lets you turn on the Wear Sensor and adjust its sensitivity. The app indicates the battery charge level of your headphones and the current firmware version at a glance. Any firmware updates from the manufacturer can be uploaded to the headphones from the app. The app is compatible with iOS (10.0 or later) and Android (5.0 and up) devices.

Intuitive Self-controls: Proximity sensors placed around the ear cups allow the PX headphones to perform specific actions automatically. The headphones enter standby mode and disconnect from any connected Bluetooth devices two minutes after you remove them from your head. They automatically wake from standby and connect to the last connected Bluetooth device when you put them on. When you lift an earcup or place the headphones around your neck, your music pauses. Playback resumes when you place them back on your head.

Rechargeable Battery: The headphones are powered by a rechargeable Lithium Polymer battery that is charged via USB with the supplied USB-C cable. With a 3 hour full charge, the PX Wireless offers the following battery life:

  • Bluetooth + ANC: Up to 22 hours
  • Bluetooth (no ANC): Up to 29 hours
  • Wired + ANC: Up to 33 hours
  • Wired (no ANC): Up to 50 hours

Ear Cups and Drivers: The PX wireless headphones feature reference-quality 40mm dynamic drivers that are angled inside the ear cup for a realistic soundstage. The over-ear design and soft leather memory foam cushions help to block most ambient noise and keep your music inside the ear cups. The removable magnetic ear pads allow you to replace the pads if they gets damaged.

Folding Design: The ear cups swivel so you can fold them flat for compact storage in the supplied soft padded pouch.

Cables: The B&W PX wireless headphones can be used with a wired connection, if desired. Wired connections are useful on an aircraft or when listening to music on a traditional stereo system or computer. You can still utilize ANC when using a wired connection to shut out ambient noise. A 51" mini-jack (3.5mm) audio cable and a 48" USB-C cable are included.

Note: When using a wired connection, you still need to power on the headphones, and the volume, answer/end call, and play/pause buttons do not function.

On-board Controls: The on-board controls on the back of the right ear cup let you raise and lower the volume, and control the music playback (play, pause, next track, previous track) while you're in active mode (using Bluetooth). The controls will not operate when used in passive (wired) mode. The PX Wireless headphones also have two microphones for clear phone conversations.


  • Frequency Response: 10Hz to 20kHz
  • Impedance: 22 ohms (passive)
  • Distortion (THD): <0.3% (1 kHz/10 mW)
  • Sensitivity: 111 dB/V at 1 kHz
  • Weight: 11.9 ounces (12.3 ounces with cable)

Great views and I had a rewards coupon on file at Crutchfield. [ CALVIN  May 03, 2018 ]
They are pricey, but I am okay investing in a device that will be used on a daily basis. I had a few must-haves for my wireless bluetooth headphone purchase: 4.0+ bluetooth, USB-C port, 20+ hours battery life, World Class Sound, Subdued looks that is stylish but not to flashy, Adjustable noise cancellation, Auto on/off when removing from head. I realize this list is pretty narrow but somehow found Bowers and Wilkins PX's that check every item! [ Christopher  Apr 25, 2018 ]
I purchased this product because I really need sound cancellation due to a seizure disorder that occurred after having a head injury. Sound can trigger seizure activity in my case.I've tried Bose products in the past and they just keep breaking, or failing, I own a pair of B&W p5 wireless headphones and I'm very happy with there build quality, so hopefully the new PX series will be helpful. [ Christopher  Mar 16, 2018 ]
After watching 10 Youtube reviews and comparison videos and checking 5 different "Best of" websites I came to the conclusion of getting these B&W PX headphones. Im not following the crowd that thinks "Beats" are actual headphones. The B&W PX have superb sound, durability, look, feel, and so much more. 2 year warranty vs all the others which offer 1. There are not enough characters allowed in this response to list all the ways these headphones are better. [ Shawn  Feb 02, 2018 ]
B&W have the best sound quality in the industry. I bought the P7 couple months ago and was absolutely blown away by the detailed sound quality, PX is a new addition to the family with a lot of features. I bought it as a birthday gift for my nephew after getting great advice and honest opinion from Crutchfield Advisor Jasan. [ DEVEN D  Dec 05, 2017 ]
Nemo from Crutchfield recommended these as the best sound quality with great noise cancelling abilities. [ Daniel  Nov 08, 2017 ]

How do these sound with an Android phone?
[ George  Sep 27, 2019 ]
2 answers
I am starting them now, streaming from my Galaxy S10. My primary use for the first 2 years was on commercial sir flights using my S7. Great sound, a little warm and a little bulky, slightly more than the Sonys I used to use, but the noise reduction is superb.
[ Clifford  Sep 28, 2019 ]
I ended up returning them. They were much too heavy due to their tank-like construction. I went with the Sonys. Love them. Much better than the Bose, in my opinion.
[ Dave  Sep 27, 2019 ]
Can the battery be removed and replaced when it no longer works?
[ Ed  Dec 14, 2018 ]

Sorry dont know. Haven't had to do that yet.
[ Rebekah  Dec 15, 2018 ]
[ Martin  Dec 14, 2018 ]
I don't know, have not noticed a deterioration in battery life in the 2 years I have had these. This includes 2 ti 6 long plane flights, using the headphones 6 to 8 hours.
[ Clifford  Dec 14, 2018 ]
Do any of the buttons on these cans allow one to interact with or trigger Siri on a paired Apple device?
[ Daniel  Oct 25, 2017 ]
1 answer
The headphones are not Apple-specific so, no; they do not offer a button to trigger Siri.
[ Ryan  Nov 01, 2017 ]  Staff
I have read about the "smart" functions that these cans exhibit, i.e. lift a cup and the music pauses. My question is: is there any way, either via the companion app or on the device itself, to DISABLE that "smart" functionality? One review I read from The Verge indicated that this functionality triggered in unexpected ways.
[ Daniel  Oct 25, 2017 ]
4 answers
Yes, you can turn off the Smat feature via the app and will stay in the last mode for next use.
[ Marcia  Oct 30, 2017 ]
Yes, you can disable it in the iPhone app. Just swipe left on the top portion of the app to access it.
[ Michael  Oct 30, 2017 ]
Yes, you can disable all the smart features on the B&W app.
[ Vineet Raj Govi  Oct 30, 2017 ]
Yes it can be disabled however it is an all or nothing option. Either all smart options are on or they are all off. It is managed through the app.
[ Jorge  Oct 30, 2017 ]
I have for years happily owned reference-quality (Silver signature - interested in selling them) loudspeakers from B & W and so I have been dreaming about headphones. Can I connect these to an old-school stereo?
[ Erich  Oct 09, 2017 ]
1 answer
The B&W PX Wireless headphones include a detachable miniplug cable for optional wired listening--if your stereo system only has a 1/4" headphone output, you can use a 1/4" adapter (sold separately) like this: For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
