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
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.
