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.
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.
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.
For convenience, the press-to-talk switch is ergonomically positioned on the headset.
The Magna headset’s robust mechanical design and construction survive rough handling in harsh environments.
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.
