Hybrid ANC + ENC Noise Cancellation

Uses Hybrid Active Noise-Cancellation (ANC) and Environmental Noise-Cancelling (ENC) to reduce unwanted noise. Hybrid ANC earcup mics minimise ambient distractions while allowing critical sounds such as fire alarms for health and safety awareness. The ENC mic filters background noise so your voice stays clear on calls.

Multi‑Point Bluetooth® 5.4 Connectivity

Multi-point Bluetooth® 5.4 technology allows pairing with up to eight devices, with two active at the same time. Seamlessly switch between your phone and laptop without re-pairing, allowing one headset to support laptops, tablets and smartphones.

Earcup Controls + Flip-to-Mute Mic

Integrated earcup controls let you adjust volume, play/pause audio and answer/end calls* directly from the headset. The flip-to-mute mic allows you to mute instantly by rotating the mic upward. * Call controls work with native mobile cellular calls only and are not supported for UC or VoIP applications (such as Microsoft Teams, Zoom or Webex).

Adjustable Padded Over‑Ear Design

An adjustable headband and soft, padded over-ear cushions deliver a secure, comfortable fit while evenly distributing weight to reduce pressure during extended use. The closed back, over-ear design adds passive noise cancellation for improved audio immersion. The ergonomic design supports hours of calls or focused listening.
