The EARMOR M32 is an electronically amplified noise-canceling headset designed for special missions with
communication capabilities. In various extreme environments, the headset can amplify subtle environmental
sounds and accurately track human voices, providing users with outstanding sound reproduction and optimization.
Especially in high-noise environments such as artillery fire and gunshots, which exceed 82dB of dangerous
noise, it can effectively isolate and protect the user's hearing while enhancing the clarity of conversations and
awareness of the surrounding environment. M32 utilizes advanced acoustic technology to effectively reduce
ambient noise. With five-level volume adjustment, it can meet the demands of various users. Even in the powered-
off state, the headset can enter the maximum hearing protection mode to protect your hearing. Moreover,
featuring a foldable headband, it is convenient for storage and suitable for players with different needs, whether
for outdoor or indoor shooting ranges. Powered by 2 AAA batteries, the battery life can reach up to 200 hours,
and replacement is easy. The newly added quick-detach function allows seamless accessory switching even
in hazardous environments. EARMOR M32 not only provides users with outstanding hearing protection but also
ensures clear and stable communication capabilities, making it an ideal choice for carrying out special missions.
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.
