NShi M91-WM Bluetooth 5.3 headphone, 60 h, 95 % ENC, 350 mAh

NShi M91-WM Bluetooth 5.3 headset

The NShi M91-WM is a wireless on-ear headset built for professionals who spend long hours on calls. It connects via Bluetooth 5.3 and includes a USB dongle for stable computer links. Dual microphones with ENC technology suppress 95% of background noise so speech stays clear in loud environments. The adjustable headband and leather cushions keep it comfortable through extended shifts.

Battery life and charging limits

A 350 mAh battery delivers up to 60 hours of talk time and recharges fully in about three hours via Micro-USB. Bluetooth 5.3 maintains a reliable link within roughly 10 metres of the source device. The headset supports multipoint pairing so you can switch between two connected devices without re-pairing. Range and stability drop when walls or heavy wireless traffic intervene.

Capacity and headroom for daily use

Sixty hours of talk time covers a full work week of calls without needing a recharge. The 95% ENC reduction handles steady noise such as engine hum or office chatter effectively. Sudden loud sounds or overlapping voices may still leak through the microphones. Users who need active noise cancellation for listening to music or who prefer over-ear cups for passive isolation will find this on-ear design insufficient.
