Description
The CH-3 headset is ideal for workers in loud environments who need their own headset to ensure hygiene standards are as high as possible. Some users prefer a built-in PTT on the ear cup, whereas an external PTT mounted in-line, such as on the chest, is more convenient for others. As a result, the CH-3 communication headset is available in two formations – see the description below for more details.

CH-3 Communication Headset – no built-in PTT
- MT74H52A-110 (Headband)
- MT74H52B-110 (Neckband)
- MT74H52P3E-110 (Helmet mounted)
Instead of having a PTT on the ear cup of your CH-3 headset, connect your headset to your radio in one of two ways:
- Radio > inline PTT unit with correct radio connection* > plugs into CH-3 headset
- Radio > FLX2 cable with correct radio connection* > plugs into standard inline PTT unit > plugs into CH-3 headset
CH-3 Communication Headset – with built-in PTT
- MT74H52A-111 (Headband)
- MT74H52B-111 (Neckband)
- MT74H52P3E-111 (Helmet mounted)
Connect your CH-3 headset directly to your radio with the FLX2 cable with correct radio connection*, and use the built-in PTT on your headset.
