CRS HDHSOHDI dual-input, 'over the head', heavy-duty noise-cancelling headset

The CRS HDHSOHDI dual-input, ‘over the head’, heavy-duty noise-cancelling headset enables the user to connect one headset to two different radios, with a separate PTT for each radio on each earmuff (one red and one black PTT on each earmuff). It also has a listen-only input for receiving audio from a third device if required.

The boom can be fitted with a dynamic microphone for high-noise environments, eg, motor racing, or an electret microphone for normal environments, eg, construction and forklift operators. The unit has been fitted with strain relief, meaning that all the pressure is placed on the Kevlar-reinforced cable; if the cable gets caught in machinery, the strain relief prevents damage occurring to the earmuff.

The headset and cable come with a positive-action earmuff PTT and inline PTT. NRR is -24 db.
