The EARMOR M31 Plus is an electronically enhanced noise-canceling headset designed for specialized tasks.
It features communication capabilities and is capable of enhancing subtle environmental sounds, tracking
human voices with high fidelity optimization, while also blocking dangerous noises exceeding 82 decibels (such
as explosions and gunshots). It not only protects hearing, enhances conversation clarity, but also increases
situational awareness of the surrounding environment. The built-in EMI filtering system effectively eliminates
electromagnetic interference generated by other electronic devices. The M31 Plus is equipped with an AUX
interface, allowing connection to smartphones, tablets, computers, and other players using a compatible 3.5mm
audio cable, meeting individual entertainment needs. The newly added quick-detach function also allows for easy
switching of accessory attachments in hazardous environments.
For the best protection, ear cushion sealing ring should seal firmly against head, Anything that interferes with the
seal --- such as long hair(pull back to the extent possible), thick or poorly fitting eyeglass temples, pencils or
caps will lessen the protection.
- Earmuffs must be regularly inspected for cracks or worm parts and replaced as needed. Typical life for
foam cushion sealing rings is 12 months.
- Clean the exterior of the hearing protector regularly with soap and warm water.
Do not immerse the whole headset in water.
- Do not store the hearing protector behind a windshield or at temperatures above 131°F(55°C).
- Certain chemical substances may damage this product. Contact the manufacturer for more information.
- The product is suitable for transport in original packaging.
- The earmuffs passes small, meduim and large size ranges, compliant to EN 352- 1:2020.
