BUY IF
- You want genuine electronic hearing protection for dedicated shooting practice, range days or instructing.
- You value real ambient awareness — five volume levels let you dial in how much of the outside world you want to hear.
- You want the option to connect a radio or media device via the 3.5mm aux input without needing Bluetooth.
- You want a genuinely long-lasting headset — up to 60 hours on two easy-to-replace AAA batteries.
NOT IDEAL IF
- You need NATO-standard radio PTT compatibility — the M32 Plus adds a detachable boom mic and U-174 connector for that.
- You want the lowest possible profile for wear under a helmet — the M23T AI in-ear system fits that role better.
Product Overview
The Earmor M31 Plus is a digital noise-canceling headset engineered to protect your hearing during shooting practice. It effectively reduces harmful noise while amplifying ambient sounds, enhancing your awareness of voices, movements and gunfire for a safer, more responsive training experience.
Digital circuitry suppresses impulse noises exceeding 82dB in under a millisecond, with smooth, natural sound recovery that keeps you focused and aware in dynamic shooting environments. Integrated EM/RFI shielding ensures clear, uninterrupted audio even around communication devices and tactical radio systems, while a 3.5mm audio input lets you connect a radio or media device directly.
Premium gel ear cushions provide genuine comfort during long hours of wear, with a sweat-resistant, sound-leakage-proof seal that maintains isolation while reducing fatigue — built for extended use at both indoor ranges and outdoor training.
