Audio T Verdict
The Bowers & Wilkins Pi6 combines an engaging, detailed sound with effective noise cancellation, clear calls and a compact design suited to everyday listening.
Its 12mm bio-cellulose drivers and high-performance 24-bit processing give music impressive clarity and weight, while aptX Adaptive can provide a higher-quality Bluetooth connection with compatible devices.
Eight hours of earbud playback with noise cancellation enabled, a further 16 hours from the charging case and four ear-tip sizes make the Pi6 a strong all-round choice for commuting, travel, exercise and general use.
Bowers & Wilkins Pi6 True Wireless Noise-Cancelling Earbuds
The Pi6 is a pair of high-performance true wireless earbuds designed to bring Bowers & Wilkins sound quality to everyday mobile listening.
Each earbud combines a 12mm bio-cellulose drive unit with high-performance digital signal processing, adaptive Active Noise Cancellation and three microphones for calls and environmental noise control.
Bluetooth 5.4, aptX Adaptive, multipoint connectivity and the Bowers & Wilkins Music app provide a flexible listening experience across compatible smartphones, tablets and computers.
12mm Bio-Cellulose Drive Units
Each Pi6 earbud uses a 12mm bio-cellulose drive unit developed to provide low distortion, controlled bass and detailed high-frequency reproduction.
Bio-cellulose combines low moving mass with useful rigidity, helping the driver respond quickly while avoiding excessive resonance.
The result is a clear and balanced presentation that can reveal fine detail without losing the musical weight and energy required by modern recordings.
High-Performance 24-Bit Processing
The Pi6 uses high-performance digital signal processing and supports a true 24-bit wireless audio connection with compatible source equipment.
The internal processing controls the drivers, noise cancellation, calls and sound adjustment while maintaining the tonal character intended by Bowers & Wilkins.
Actual connection quality will depend on the transmitting device, selected Bluetooth codec, source material and surrounding wireless conditions.
24-Bit Does Not Mean Every Connection Is Identical
aptX Adaptive requires a compatible transmitting device. Other products may connect using aptX Classic, AAC or SBC instead.
The Pi6 will select an appropriate supported codec automatically when paired with a phone, tablet or computer.
aptX Adaptive Bluetooth
aptX Adaptive is designed to adjust its operation according to the content being played and the quality of the wireless connection.
This can help balance sound quality, connection stability and delay when listening to music, watching video or using other compatible applications.
The Pi6 also supports aptX Classic, AAC and SBC, providing compatibility with a wide range of Bluetooth devices.
Adaptive Active Noise Cancellation
The Pi6 uses built-in microphones and digital processing to reduce unwanted environmental noise.
Its Active Noise Cancellation system adapts to the surrounding conditions, helping reduce distractions from transport, offices and other busy environments without requiring constant manual adjustment.
A secure seal between the ear tip and ear canal is essential. An unsuitable ear-tip size can reduce both noise-cancelling performance and bass response.
Ambient Pass-Through
Ambient Pass-Through allows external sound to reach the listener without removing the earbuds.
This can be useful when listening for travel announcements, speaking briefly to another person or remaining more aware of the immediate surroundings.
Noise Cancellation, Pass-Through and environmental processing can be controlled from the earbuds or through the Bowers & Wilkins Music app.
Remain Aware of Your Surroundings
Pass-Through is a listening aid rather than a substitute for normal attention and judgement.
Remove the earbuds whenever full awareness is required, particularly near traffic, machinery, railway platforms or other potential hazards.
Three Microphones Per Earbud
Each Pi6 contains three microphones used for telephony and Active Noise Cancellation.
The microphone system is designed to capture the wearer’s voice while managing surrounding noise, helping calls remain clear in a range of everyday environments.
Call quality will still depend on the mobile network, application, device and level of environmental noise.
Comfortable and Secure Fit
The Pi6 is supplied with extra-small, small, medium and large silicone ear tips.
The medium tips are fitted as standard, but the best size may differ between the left and right ears.
A correct fit should feel secure and comfortable while creating an effective acoustic seal. The earbuds should not require excessive pressure to remain in place.
Try Every Ear-Tip Size
The correct ear tip can noticeably improve comfort, bass, noise cancellation and stability.
Insert each earbud and twist it slightly backwards until the tip sits comfortably within the opening of the ear canal.
Wear-Sensing Playback
Wear sensors in both earbuds can pause playback when either earbud is removed.
Music automatically resumes when the earbud is returned to the ear, creating a natural listening experience without requiring the phone to be handled.
The sensors also help conserve battery power when the earbuds are removed and left outside the charging case.
Wear sensing can be enabled or disabled through the Bowers & Wilkins Music app.
Touch-Sensitive Controls
Each earbud has a touch-sensitive multifunction area on its outer surface.
The controls provide access to music playback, track selection, calls, Voice Assistance and environmental modes.
Selected press-and-hold functions can be customised through the Music app, allowing the controls to suit the user’s preferred setup.
Bluetooth 5.4
Bluetooth 5.4 provides the wireless connection between the Pi6 and a compatible phone, tablet or computer.
The earbuds enter pairing mode when the charging case is opened for the first time. Further devices can be added manually or with assistance from the Music app.
Google Fast Pair is supported on compatible Android devices, while Apple Made for iPhone support helps provide straightforward operation with iOS products.
Multipoint Connectivity
Multipoint allows the Pi6 to remain connected to two Bluetooth devices simultaneously.
This can be useful when working across a phone and computer, allowing music to be played from one while remaining available for calls from the other.
Only one connected device can play audio or make a call at a time. Pausing the first device and starting playback on the second prompts the earbuds to change source.
Incoming Calls Take Priority
If a call arrives on the second connected device while music is playing from the first, playback will pause and the call will be routed to the Pi6.
Connections and previously paired devices can be managed through the Bowers & Wilkins Music app.
Bowers & Wilkins Music App
The Bowers & Wilkins Music app is available for compatible iOS and Android devices.
The app supports initial setup, direct access to compatible music services and control over the earbuds’ principal features.
Available settings include:
- Active Noise Cancellation
- Ambient Pass-Through
- Environmental modes switched off
- Two-band sound adjustment
- Wear-sensor control
- Bluetooth connection management
- Earbud battery information
- Product renaming
- Firmware updates
Basic Bluetooth listening remains possible without the app, but installing it provides access to the complete feature set and future software updates.
Two-Band Customisable EQ
The Music app provides two-band tone adjustment for tailoring the balance of the Pi6.
This allows the listener to make modest changes to the bass and treble according to taste, recording quality and listening conditions.
Start with the controls in their neutral positions and make small adjustments. Excessive equalisation can reduce headroom or make recordings sound unnatural.
Eight-Hour Earbud Battery Life
The Pi6 provides up to eight hours of earbud playback with Active Noise Cancellation enabled.
Battery life will vary according to listening volume, codec, calls, environmental processing, device settings, temperature and general use.
The battery level of each earbud can be checked through the Music app, while the indicator on the case provides a quick visual status display.
Up to 24 Hours with the Charging Case
The charging case provides a further 16 hours of battery capacity, giving up to 24 hours of combined playback before the case itself must be recharged.
Placing the earbuds in the case automatically switches them into standby and begins charging.
The case should normally be closed after the earbuds are inserted to ensure that they are stored securely and ready for the next listening session.
Fast Charging
A 15-minute charge provides up to two hours of additional playback.
This can be particularly useful before a commute, meeting or short journey when there is not enough time for a complete charge.
A full charge takes approximately two hours under the conditions specified by Bowers & Wilkins.
USB-C Charging
The charging case is powered through its USB-C socket using the supplied 60cm USB-C to USB-C cable.
The cable can be connected to a suitable USB power supply or powered computer port.
A mains charging adaptor is not listed among the supplied accessories and may need to be obtained separately.
No Wireless Charging
The Pi6 charging case does not support Qi or other wireless charging pads.
It must be charged through its USB-C connection.
Standard Charging Case
The Pi6 case stores and charges the earbuds but does not include the wireless audio retransmission feature found on the Bowers & Wilkins Pi8.
Audio reaches the Pi6 earbuds directly through Bluetooth from a compatible phone, tablet, computer or other Bluetooth source.
The case measures 65mm wide, 29mm deep and 52mm high, making it compact enough for many pockets and small bags.
IP54-Rated Earbuds
The Pi6 earbuds carry an IP54 rating for resistance to limited dust ingress and splashing water.
This makes them suitable for exercise, commuting and everyday outdoor use when handled appropriately.
The IP54 rating applies to the earbuds, not the charging case. The Pi6 is not designed for swimming, showering, submersion or exposure to powerful water jets.
Keep the Charging Case Dry
Do not expose the charging case or its USB-C socket to rain, sweat or other moisture.
Allow damp earbuds to dry fully before returning them to the case, and do not attempt to charge the product while any connection is wet.
Exercise and Everyday Use
The secure in-ear fit and IP54-rated earbuds make the Pi6 suitable for many gym sessions, walks and general exercise routines.
Fit should be checked before beginning vigorous movement, particularly if the earbuds have recently been cleaned or a different ear-tip size has been fitted.
The Pi6 should not be used for swimming or activities where it may become submerged.
Using One Earbud
The Pi6 wear sensors and controls are designed around a pair of true wireless earbuds, although Bluetooth operation may allow individual-earbud use in suitable situations.
Feature availability, microphone behaviour and control functions may differ when only one earbud is worn.
For the intended stereo, noise-cancelling and call performance, use both earbuds whenever practical.
Cleaning and Care
Clean the earbuds and charging case using a soft, clean cloth that is dry or only lightly dampened.
Do not use detergents, rubbing alcohol, solvents, chemical cleaners or abrasive materials.
Inspect the ear tips and acoustic openings regularly, as a build-up of dirt or earwax can affect fit, volume and tonal balance.
Make sure the earbuds and case are dry before charging or storage.
Software Updates
Bowers & Wilkins may release firmware updates that refine performance, resolve issues or add features.
The Music app will provide a notification when an update is available and guide the user through the installation process.
Keep the earbuds and case adequately charged and close to the phone while an update is taking place.
Finish Options
The Pi6 is available in:
- Cloud Grey
- Forest Green
