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. A noise-cancelling microphone delivers optimum speech clarity for reduced “call-back/read-back” events. The headset can be operated in two channel mode. Soft acoustic foam ear pads and patented two-piece automatic headband deliver first class comfort with a perfect, secure fit. A flip away headphone allows for single-sided listening and a reinforced flexible microphone boom allows for left or right sided use. The headsets feature a single sided cable which is easy to exchange. Sennheiser ActiveGard® technology protects users hearing against acoustic injury caused by a sudden sound burst on the line, without interrupting communications - an added safety feature that differs from traditional acoustic shock clipping circuitry. 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®) Features Sennheiser Voice Clarity for accurate communication, provides excellent voice transmission and reception Perfect speech transmission Noise-cancelling microphone filters out ambient noise for optimum speech clarity to reduce “call-back/read-back” events Fits every application with a choice of electret/dynamic microphone, and single sided or dual sided earcup model Two channel stereo application for multi-channel communication What's in the box?
