Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

The verdict
The updated entry point into B&W's headphone line looks familiar but promises an "evolved" experience over its predecessor. The iterative design process has paid off here because it's hard to find fault with these headphones.
✓Liked: Excellent sound tuning, Good ANC, Good transparency mode, Low profile, stylish design
✕Could be better: No water resistance
