Noise cancelling
Bose often edges continuous low-frequency drone (planes, HVAC). Sony is excellent and more “tunable” in the app. Both crush daily commute noise.
Sound & app
- Sony: more EQ flexibility; LDAC for Android high-res wireless.
- Bose: tuned for an easy “wow” out of box; Immersive Audio is polarizing — try before committing.
Comfort & calls
Clamp force and pad shape are personal. Call quality varies by firmware — check recent reviews for your OS.
