How We Tested This Product

Our rigorous, independent testing process

Purchased
November 2025
Testing Period
30 days
Tested By

Sound Quality & ANC Testing

We evaluated audio performance using a standardized suite of tracks across genres (e.g., FLAC files via Tidal, pink noise for frequency response) on a Head Acoustics rig measuring distortion, bass response, and imaging. ANC was tested in real-world scenarios: airplane cabin simulation (85dB white noise), subway rumble, and office chatter, comparing attenuation to baselines like Sony XM5.

Comfort, Battery & Durability

Headphones worn for 8+ hour sessions by multiple testers (with/without glasses) scoring clamp force and heat buildup. Battery drained fully with ANC on at 50% volume, timing playback via auto-pause tests. Durability checked via 100x hinge flexes and drop tests from desk height.

Wireless Features

Paired with 10+ devices testing multipoint switching, codec support (SBC/AAC), and app functionality on iOS/Android. Call quality assessed in windy conditions with voice memos.
