EPOS COMMAND HMD 46-31-II

The HMD 46‑31‑II is a dual‑ear, ultra‑lightweight noise‑cancelling headset from EPOS (formerly Sennheiser), tailored for professional use in air traffic control (ATC) and command, control & communications (C3) environments .

• Noise‑cancelling dynamic microphone for clear voice transmission and reduced “call‑back/read‑back” events.
• Flip‑away ear cups for single‑sided listening when needed.
• Patented split headband + soft acoustic‑foam pads ensure all‑day comfort.
• Lightweight design (~150 g) with flexible boom microphone deployable left or right.
• Two‑channel stereo compatibility allowing simultaneous communication streams.
• Optional EPOS ActiveGard® for acoustic protection (the 46‑31‑II variant omits ActiveGard, unlike the 46‑3‑II version).
