Product Identity

The 3M MT13H223A is an electronic ear muff headset with a 26 dB noise reduction rating. It is built for shooters and industrial workers who need hearing protection combined with audio input. The over-the-head design uses a green cup and black PVC-stainless steel band. Power comes from AA alkaline batteries.

Build Integration

The headset connects through a 3.5 mm stereo jack and includes a 3.5 mm auxiliary input for external audio sources. It requires no radio pairing or dielectric rating, so it fits directly into wired communication systems. The rigid cup structure and foam cushions allow extended wear without additional mounting hardware. AA battery power keeps the electronics independent of vehicle or panel power.

Thermals Noise Power

Passive attenuation meets ANSI S 3.19-1974 at 26 dB, reducing impulse and continuous noise without active cooling. Electronic circuitry draws minimal current from AA cells, producing no audible fan noise or heat during normal operation. The wired connection eliminates RF emissions and battery drain from wireless protocols. Foam cushions maintain seal integrity in varying temperatures.
