Bowers & Wilkins Px7 S2e MDAQS
Multi-Dimensional Audio Quality Scores, Scale 1 - 5
Virtual mean opinion scores (MOS) on a 1–5 scale, modeled from the measured response by HEAD acoustics’ MDAQS (Multi-Dimensional Audio Quality Score) model. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
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
