The AG-11S is a single-sided overhead headset designed for professionals who need reliable radio communication while maintaining awareness of their immediate surroundings. It covers only one ear, leaving the other open to monitor environmental cues such as equipment noises, vehicle movements, or verbal instructions from colleagues.
This single-sided configuration makes the AG-11S particularly suitable for roles that require continuous situational awareness alongside radio communication. The covered ear delivers 28dB passive noise reduction to protect hearing and improve speech intelligibility, while the open ear preserves natural hearing of the work environment. The headset features an adjustable headband, flexible boom microphone, and oversized PTT button for gloved operation.
