Applications

The 3M™ PELTOR™ CH-3 Headset with PTT Neckband (MT74H52B-111) is a rugged, wired communication solution specifically engineered for workers who must balance high-noise protection with the need to wear other headgear like helmets or welding shields.

The “B” in the model number denotes the Neckband style, which shifts the support wire to the back of the neck, while the -111 designates the built-in Push-to-Talk (PTT) button on the earcup.

  • Aviation Ground Support & Maintenance


    Ground Handling: Used by ramp agents and baggage handlers who often wear specialized high-visibility caps or bump guards that won't accommodate a standard headband. Engine Maintenance: Technicians in tight spaces (like engine nacelles or wheel wells) use the neckband style to avoid the headset being knocked off by low-clearance structures.

  • Specialized Construction & Engineering


    Pulp and Paper / Steel Mills: In environments with high heat or chemical exposure, workers often wear face shields or respirators. The neckband design ensures the headset doesn't interfere with the straps of other essential PPE. Assembly Lines: The "Speech Optimized" CH-3 speakers specifically filter out the background "whine" of pneumatic tools and conveyors, making it easier to hear instructions from supervisors.

  • Agriculture & Forestry


    Heavy Machinery: For tractor or harvester operators who wear wide-brimmed hats for sun protection, the neckband allows for consistent hearing protection ($30\text{dB}$ SNR) and communication. Tree Surgery: Arborists wearing climbing helmets with integrated visors find the neckband style more stable during active movement.
