Applications

The 3M™ PELTOR™ CH-3 FLX2 Headset with PTT (Push-To-Talk) is a professional-grade protective communication solution. It is specifically designed for high-noise environments where clear, reliable two-way radio communication is critical for safety and productivity. 

Because this model includes a built-in PTT button on the ear cup and uses the flexible FLX2 cable system, it is widely used in industries requiring constant coordination.

  • Pulp and Paper / Steel Mills


    These environments often have high levels of electronic interference and massive amounts of metal that can disrupt Bluetooth signals. The wired CH-3 provides a fail-safe, interference-free connection to a radio. Why it fits: The speech-optimized speakers are specifically tuned to cut through the low-frequency drone of heavy industrial rollers and furnaces.

  • Airport Ground Handling & Push-Back


    While the XPI is also used here, the CH-3 is often preferred for "tug" operations where a physical connection to the aircraft’s intercom system (via a specialized FLX2 cable) is required for safety and reliability. Integrated PTT: The large, built-in Push-To-Talk button on the earcup is easy to find and press even while wearing thick ground-crew gloves.

  • Agriculture and Forestry


    Outdoor environments involve mud, rain, and debris. The CH-3 features an IP68-rated microphone, which is fully submersible and dust-tight. Application: Logging teams or heavy tractor operators use the CH-3 because it can withstand the vibration and "dirty" nature of the work better than many consumer-grade electronics.

  • Construction & Demolition


    On busy sites where teams already have a fleet of radios (Motorola, Kenwood, Hytera, etc.), the CH-3 acts as the perfect peripheral. FLX2 System: The "FLX2" in the name refers to the 6-pin connector. This allows you to swap cables rather than the whole headset if you change your radio fleet, making it a favorite for long-term infrastructure projects.
