🧭 Performance & Experience

Sound Quality
TechRadar describes the sound as “big and bold,” with some low-frequency emphasis but not overly bass-heavy, offering a satisfying balance and separation for closed-back cans—especially for smaller head sizes 
Reddit reviews praise the sound:

“Bass is punchy … mids are crisp and clear … highs are nice … soundstage and instrument separation is also really good for a closed back” 
Some mention less energetic vocals and a more neutral mid-treble character, especially for rap or pop energy 

ANC & Transparency
Most reviews point to very capable ANC—comparable to Sony and Bose in many conditions—with adaptive behavior that responds to changing noise levels. Wind cancellation works generally well; transparency mode is functional though not flawless in very noisy settings 

Battery & Charging
An impressive 50-hour battery life with ANC, with ultra-fast charging providing 5 hours of playback in just 10 minutes. Full recharge takes around 3.5 hours 

Comfort & Fit
Weighing ~277 g and featuring plush earcups and soft headband, the fit is comfortable—especially for users with smaller head sizes. However, the clamp can feel snug on larger heads 

Call & Mic Quality
Beamforming microphones provide clarity, though wind and ambient noise can limit performance—call clarity is occasionally rated as "just okay" in extreme environments
