Detailed Review

Microphone Reality: Retractable arm positions perfectly at mouth level. Passive noise reduction (not true ANC) cuts office chatter 60-70%. Crystal clear for clients; background acceptable in home offices. 3-second “M” hold switches devices.

Connectivity: Bluetooth 5.0 stable to 33ft clear line. USB dongle essential for Windows desktops without Bluetooth. Dropping issues in dense WiFi—stay 10ft from routers.

Comfort Engineering: 8oz lightest in class. 4″ memory foam earpads breathe better than pleather. Adjustable headband fits small-to-large heads. Minimal clamp force prevents headaches.

Battery Performance: 50 hours talk time verified (8-hour days = full week). 96 hours music optimistic but 60-70 hours realistic. 2-hour USB-C charge.

Audio Quality: Call-optimized mids/highs. Bass present but not audiophile-grade. Sufficient for podcasts, sufficient for calls, suboptimal for EDM/movies.

Pakistan Offices: Call center agents, remote freelancers benefit from dongle reliability. Dera Ismail Khan home offices eliminate microphone fiddling.

Who Should Buy This Product

Perfect for:

• Call center professionals.

• Remote workers (Zoom/Teams).
