PX
Wireless Headphone
ENGLISH
Welcome to Bowers & Wilkins and PX Wireless Headphones
Thank you for choosing Bowers & Wilkins. When John Bowers first
established our company he did so in the belief that imaginative design,
innovative engineering and advanced technology were keys that could
unlock the enjoyment of audio in the home. His belief is one that we
continue to share and it inspires every product we design.
PX is a high performance over-ear headphone that provides the highest
quality personal audio experience combined with the convenience of
wireless operation based on the latest Bluetooth audio standards. This
manual will tell you everything you need to know to get the most from
your PX.
PX can be used either wirelessly, to play music streamed from your
mobile phone, tablet or computer using Bluetooth wireless technology,
or conventionally in “passive” mode connected by a cable to a suitable
headphone output. PX can also be used for wireless telephony.
For wireless use, PX incorporate a rechargeable battery pack. When fully
charged, the battery pack can provide up to 17 hours use at average
volume levels. Battery power is not consumed when PX is used with
a cable.

2. Getting to know PX
ANC control button
Once switched on via the Power slide-switch on its
right hand ear piece, PX is controlled via Bluetooth,
Play/Pause, Volume + and Volume – buttons. An
indicator alongside the Bluetooth button displays
Bluetooth connection state and battery charge level.
PX also provides audible feedback for some control
commands and events.
On/Off and Bluetooth
control button
Note: It is possible to toggle the audio cues on
and off by press and releasing ‘Play/Pause’ and
‘+’.
A USB charging socket and connection socket for
the audio cable, that enables PX to be used as a
passive headphone, is located in the right hand ear
piece with a pin-hole reboot button beneath the
ear pad. Connecting the audio cable is covered in
Section 10.
3. PX Battery Charging
PX is shipped with battery power and may be used
immediately, however, it is good practice to charge
the battery fully before first use. It can take up to
3 hours for PX to reach full charge however it is
possible to use PX while the battery is charging.
Note: The indicator initially displays battery
charge when PX is switched on. Green means
that the battery is above 30% charged. Yellow
means that the battery is between 30% and 10%
charged. Red means that the battery is below
10% charged. If the indicator blinks red, the
battery charge is too low for PX to operate.

Proximity sensors
Note when the LED blinks red PX will not power
on.
To charge PX follow the steps described below.
Using the supplied USB charging cable, connect
the headphones to a powered USB socket; either a
computer USB socket, a mains plug USB charger or
an in-car charger.
While charging, the indicator will blink green. As
the level of charge increases the illuminated period
of the blink will get longer. When fully charged the
indicator will stay illuminated green.

4. Switching On and Off
To switch PX on slide the power button to the right
and hold for 1 second. To switch off slide the power
button to the right and hold for 2 seconds. PX will
provide audible feedback as it switches on or off.
Note: If PX is left switched on but inactive for
more than 10 minutes it will automatically turn off
to save battery power. It can be woken by sliding
the power button to the right.
5. Wearing your PX
Using your headphones correctly will help ensure
that their performance reaches its full potential. First,
identify the left and right ear pieces. Identification
legends are engraved on the metal hinge below the
headband.
Diagram 3
Identifying left and right
This is illustrated in Diagram 3.
Now unfold the headphones and slide them on to
your head with the headband adjusted so that each
ear piece sits comfortably over the ear.
This is illustrated in Diagram 4.
It is recommended that you fold and return your
headphones to their pouch when not in use.
6. Bluetooth Pairing your PX
To connect your PX to a Bluetooth enabled audio
device it must first be “paired” with the device. Once
paired, a Bluetooth device and PX will “remember”
each other and be able to connect when within
range.
PX can remember up to eight paired Bluetooth
devices. The first paired device is automatically
designated as the “primary” device. Additional
devices are designated as “secondary” devices.
The primary device will automatically connect when
PX is powered on and within range. Secondary
devices will not connect automatically when in
range but must be connected using their Bluetooth
settings menu.
At any time, a press of the Bluetooth button will
force PX to connect to the primary device, if it is
within range.
Diagram 4
Adjusting the earpiece.
It is possible for two devices to be connected to PX
simultaneously, however, audio will only be streamed
from one device at any one time.
To pair a Bluetooth device with PX follow the steps
described below.
With PX switched on, press and hold the Bluetooth
button for 2 seconds. The indicator will flash blue
and PX will provide audible feedback as it enters
“pairing” mode.
Note: PX will automatically exit from Bluetooth
pairing mode if no device is paired within 5
minutes.
Open the Bluetooth settings on the source device
and ensure Bluetooth is switched on. Once
discovered, PX Bowers & Wilkins will appear as
an available Bluetooth device. Select PX Bowers &
Wilkins and close the Bluetooth settings.
Note: If your Bluetooth audio source device does
not support “simple” pairing and requests a four
digit code, enter ‘0000’.
Once a connection has been established, ensure
that PX is selected as the speaker output for the
Bluetooth source device. Audio will then be heard
through PX.
Note: If pairing fails the indicator will flash in
2 second bursts. The most common reasons for
pairing failure are signal interference and distance
between the two devices. It is good practice to
have the two devices relatively close to each
other when pairing.
To disconnect a Bluetooth source device from
PX press the Bluetooth button twice in quick
succession. This will disconnect all Bluetooth
connected devices. PX will provide audible feedback
when Bluetooth is disconnected.
PX paired device memory can be cleared by
pressing and holding Volume – and Bluetooth button
for 2 seconds. The indicator will flash and PX will
restart once its memory has been cleared.
7. Controlling Bluetooth Audio
The PX Play/Pause, Volume + and Volume – buttons
can be used to control Bluetooth audio:
Note: The buttons are not operational when PX is
used in passive mode with a wired connection.
9. Using a mobile phone with your PX
11. Reboot
To answer a call press and release the Play/Pause
button.
To perform a reboot use a straightened paper-clip to
press and hold the Reboot button for two seconds
as illustrated in Diagram 5. The headphones will turn
off, press Power on and reboot will be complete.
To reject a call press the Play/Pause button for
2 seconds.
To end a call press and release the Play/Pause
button.
A Bluetooth stream playing while a telephone call is
taken will be paused. It will resume when the call is
ended.
10. PX wired connection
Note: Performing a reboot will not clear the
paired device memory.
12. Cleaning your PX
Clean your PX by using a damp cloth and dabbing
the leather until clean, do not rub the cloth on the
leather. Do not use cleaning detergents or leather
polish, doing so may cause damage to the product.
In addition to operating wirelessly, your PX can be
connected to a music source using the supplied
audio cable. Cable connection is useful if the battery
is low or if PX is to be used with a non-Bluetooth
audio source device.
To connect the supplied cable to your PX take one
end of the connection cable and carefully insert it
into the socket beneath on the right ear piece.
The audio cable must be disconnected for PX to
switch on and connect via Bluetooth, however its
battery can be charged while the audio cable is
connected.
Note: Connecting the audio cable will
automatically switch off the Bluetooth and
powered elements of PX. PX will not however
switch on automatically when the audio cable is
disconnected.
To increase volume press and hold the Vol + button.
To decrease volume press and hold the Vol – button.
To play audio press and release the Play/ Pause
button.
To pause audio press and release the Play/ Pause
button.
To select the next track press the Play/ Pause button
twice in quick succession.
To select the previous track press the Play/ Pause
button three times in quick succession.
8. ANC
ANC will be set to ‘Off’ as default and can be
activated by pressing the ANC button on the side of
the right ear piece. A quick press of the ANC button
will toggle the On/Off state of the ANC Mode that
has been selected by the user in the App. A longer
press will toggle the Sound Pass Through state.
Note: Sound Pass Through should work with or
without music streaming, i.e. any time ANC is
“On”.
