PTT Earmor M51 Military — Kenwood

The Earmor M51 Military is a PTT (Push To Talk) module for airsoft designed to connect compatible Earmor tactical headsets to radios with a two-pin Kenwood connector. Measuring 70x40x25 mm and weighing 40 g, it mounts on a jacket or plate carrier without restricting movement.

The transmit button is sized to be located and pressed even with gloves on — a detail that matters during dynamic scenarios where hand visibility is limited. The polymer body carries IP67 certification, meaning full dust protection and water resistance to immersion at up to 1 metre for 30 minutes: conditions easily encountered in open terrain or wet environments.

The steel clip paired with the standard Kenwood connector reflects the typical trade-off for this type of accessory: compatibility with the Kenwood family is broad and straightforward, but the M51 is not interchangeable with radios fitted with different connector layouts, such as six-pin or NATO types. Users who operate multiple radios from different manufacturers should verify compatibility before purchasing, or consider dedicated adapters.

Key points

• IP67 certification provides dust and moisture protection even in demanding field conditions.
