4. Operating Instructions

4.1. Power Management

The PX headphones feature smart power management. They automatically go to sleep when removed and resume playing when picked up. If left undisturbed for an extended period, they will enter a power-saving sleep mode. To manually power off, slide the power switch to the 'Off' position.

4.2. Audio Playback Controls

The physical buttons on the right earcup provide intuitive control over your music and calls:

• Volume Up/Down: Press the '+' or '-' buttons.
• Play/Pause: Press the center button once.
• Skip Track Forward: Press the center button twice.
• Skip Track Backward: Press the center button three times.
• Answer/End Call: Press the center button once during a call.
• Reject Call: Press and hold the center button.

The built-in sensors automatically pause audio playback when you lift an earcup or remove the headphones, and resume when placed back on your ears.

4.3. Adaptive Noise Cancellation (ANC)

The PX headphones feature adaptive noise cancellation with three modes, configurable via the companion app:

• Office Mode: Lightest ANC, suitable for reducing general office chatter or mechanical keyboard sounds.
• City Mode: Moderate ANC, effective for urban environments, reducing traffic and ambient city noise.
• Flight Mode: Strongest ANC, designed to significantly reduce engine hum and cabin noise during air travel.

You can toggle ANC on/off or switch between modes using the dedicated ANC button on the right earcup, after setting your preferred modes in the app.

5. Maintenance and Care

To ensure the longevity and optimal performance of your Bowers & Wilkins PX headphones, follow these care guidelines:

• Cleaning: Use a soft, dry cloth to clean the headphone surfaces. Avoid abrasive materials or harsh chemicals. The ear cushions are designed for easy cleaning.
• Storage: When not in use, store the headphones in their protective case to prevent damage from dust, scratches, and impacts.
• Temperature: Avoid exposing the headphones to extreme temperatures, direct sunlight, or high humidity.
• Moisture: Keep the headphones dry. Do not immerse them in water or expose them to excessive moisture.

6. Troubleshooting

If you encounter issues with your PX headphones, refer to the following common solutions:

• No Power/Headphones Not Turning On: Ensure the headphones are sufficiently charged. Connect them to a power source using the USB-C cable. The headphones cannot be used, even with a wired connection, if the battery is completely depleted.
• Bluetooth Pairing Issues: Make sure the headphones are in pairing mode (flashing blue LED). Turn off and on your device's Bluetooth, then try pairing again. Ensure the headphones are not already connected to another device.
• Intermittent Audio/Connection Drops: This can occur due to Bluetooth interference. Try moving closer to your audio source or away from other wireless devices. Ensure your device's operating system and the headphone's firmware are up to date via the companion app.
• Automatic Play/Pause Sensor Malfunction: If the auto play/pause feature is inconsistent, check the sensitivity settings in the Bowers & Wilkins Headphones app. Ensure the earcups are making proper contact with your ears.
• Noise Cancellation Performance: Ensure you have selected the appropriate ANC mode (Office, City, Flight) for your environment via the companion app. Note that ANC is most effective against consistent low-frequency sounds and less so against sudden or high-frequency noises like voices.
• Sound Quality Concerns: For optimal sound, ensure the latest firmware is installed via the Bowers & Wilkins Headphones app. If using ANC, be aware that the strongest modes may subtly affect sound characteristics.
