Summary of Features

  • Comprehensive hearing protection for high-noise environments with an autonomous, battery-powered digital active noise reduction (ANR) system
  • Crystal-clear, high-fidelity communications
  • Ergonomic construction, comfortable for long durations
  • Modular, customizable, upgradeable features and accessories to meet future requirements and extend useful life
  • Waterproof design


High-noise attenuation SNR 35dB

Our exceptional passive and active noise reduction features protect the hearing of users exposed to high levels of continuous noise.

Autonomous, battery-powered ANR

Advanced digital active noise reduction (ANR) technology improves attenuation performance at low frequencies, providing better protection. Users enjoy this protection even when untethered from a communication system.

Local sound awareness and talk-through

Our electronic compression circuitry presents local environment sounds to the wearer at safe levels, so they are more aware of hazards and risks and can have face-to-face conversations without defeating the hearing protection. The output is electronically compressed so its level does not exceed a 85 dB(A) safety level. This capability remains effective during untethered use.

Adjustable neckband

A fully adjustable neckband ensures consistent attenuation and comfort for extended durations.

Noise-canceling boom microphone

The removable noise-canceling boom microphone makes clear radio communication possible in high-noise environments, and a respirator microphone can be attached.

Removable cables

The interface cable can be detached from the headset earshell, allowing full hearing protection while untethered. Alternative cables can be attached to connect with other audio equipment.

Press-to-talk switch

For convenience, the press-to-talk switch is ergonomically positioned on the headset.

Mechanical robustness

The Magna headset’s robust mechanical design and construction survive rough handling in harsh environments.

IP68 waterproofing

Continuous outdoor use and exposure to wind and rain, snow, and ice are not a problem. The headset also withstands immersion in water.

Headset wearing options

You can wear the Magna headset with a neckband or headband, or in a soft helmet liner for bump protection. The liner supports easy attachment of protective shells.
