Redesigned Driver Technology
The PX7 S3 uses a redesigned 40mm bio-cellulose driver. While the driver material remains similar to previous models, the surrounding components—including the voice coil, suspension, and magnet system—have been redesigned.
The updated driver system is paired with dedicated amplification for each driver, providing improved clarity and better control across the frequency range.
This design reduces distortion and allows the headphones to reproduce a wider dynamic range compared to the previous PX7 models.
Sound Quality
Bass
The PX7 S3 delivers strong and well-controlled bass performance. Low frequencies are deep and impactful while maintaining clarity across different music genres.
Midrange
Vocals and instruments are reproduced clearly with balanced midrange detail. The headphones maintain natural tonal characteristics without sounding overly processed.
Treble
High frequencies remain smooth and extended, avoiding harshness even at higher volumes.
Soundstage
Despite being closed-back headphones, the PX7 S3 produces a spacious soundstage with accurate stereo imaging.
Active Noise Cancellation
The PX7 S3 features a hybrid ANC system with eight microphones. Four microphones handle noise cancellation while the others assist with voice calls and environmental monitoring.
The updated ANC platform significantly improves noise reduction compared to earlier PX7 models. Low-frequency sounds such as airplane engines and traffic noise are effectively reduced.
Transparency mode allows external sounds to pass through naturally, making it easier to hear surroundings without removing the headphones.
Design and Comfort
The PX7 S3 introduces a slimmer profile compared to previous PX7 models. The earcups use memory foam padding and are covered with soft materials for extended comfort.
The headband distributes weight evenly, reducing pressure during long listening sessions.
The headphones are available in three color options:
- Anthracite Black
- Canvas White
- Indigo Blue
Controls and App Features
Unlike many modern headphones that rely on touch gestures, the PX7 S3 uses physical buttons for playback and volume controls.
The Bowers & Wilkins Music app provides additional customization including:
- 5-band equalizer
- ANC mode selection
- Wear detection settings
- Firmware updates
Users can also enable TrueSound mode for a more neutral audio profile.
Battery Life
The PX7 S3 offers up to 30 hours of playback with ANC enabled.
Fast charging provides approximately seven hours of listening time after only 15 minutes of charging.
This makes the headphones suitable for long travel sessions and daily commuting.
