EARMOR M20T PRO Bluetooth Electronic Earbuds — Forest Green

The EARMOR M20T PRO are electronic in-ear earbuds with Bluetooth 5.4 connectivity, designed for sport shooters, hunters and airsoft players who need active hearing protection in a compact form factor that works under a helmet or alongside a full-face mask. With a declared noise reduction of 30 dB NRR, they suppress harmful acoustic peaks while keeping useful ambient sounds audible.

The AIC chip combines electronic sound compression and the passive physical protection provided by the foam tips into a single circuit. In practical terms, this means the earbuds do not simply cut everything above a threshold: they selectively reduce impulsive transients — such as a gunshot or a pyrotechnic grenade — while letting voices and directional sounds through at a safe level. The three listening modes (Quiet, Clear Voice and Ambient) let you tune the earbuds' behaviour to the situation: Quiet for already-noisy environments where you just want attenuation, Ambient to maintain situational awareness in the field, Clear Voice to prioritise the intelligibility of spoken communication.

The included charging case extends total battery life to around 50 hours, while the earbuds alone offer approximately 10 hours of continuous use. Bluetooth 5.4 allows you to connect a smartphone to listen to audio or take calls without removing your hearing protection. One trade-off worth noting: the in-ear format ensures full compatibility with helmets, external tactical headsets and full-face masks, but relies on choosing the right foam tip size to achieve a proper seal and optimal attenuation — if the tip does not seal the ear canal correctly, the actual NRR figure drops noticeably.

Key points

• Active attenuation of 30 dB NRR: protects against gunshots and impulsive acoustic peaks without completely isolating you from your surroundings.
• In-ear format: compatible with helmets, full-face masks and any headgear without interference, unlike over-ear cup designs.
• Integrated Bluetooth 5.4: stable connection to a smartphone for audio and calls without removing your protection.
• Up to 50 hours total runtime with the charging case; approximately 10 hours per single charge of the earbuds.
• Three selectable listening modes (Quiet, Clear Voice, Ambient) to adapt acoustic behaviour to the operational context.
• Declared suitable for airsoft use: effective at managing the sound of gas, AEG and HPA shots during games and training sessions.
