Overview

Sennheiser’s HME 46-II Series of very lightweight, extremely comfortable headsets are designed specifically for all air traffic control communication and C3 (Command, Control & Communications) operators requiring excellent sound and long-term wearing comfort.

The headsets feature a single sided cable which is easy to exchange.

The features an electret microphone and the series consists of three variants: HME 46 3S-II (single-sided), HME 46-3-II (double-sided) and HME 46-31-II (double-sided without ActiveGard®)
