The AG-11BD is an overhead headset with a detachable PTT cable engineered for professionals operating in high-noise environments. The quick-release connector allows the cable to be separated from the headset instantly, enabling rapid disconnection in emergency situations or quick swapping between different PTT cable configurations for use with various radio systems. Delivering 28dB passive noise reduction, the AG-11BD effectively attenuates harmful ambient noise from aircraft engines, heavy machinery, and industrial equipment while preserving speech intelligibility. The over-head design incorporates an adjustable headband and soft silicone ear cushions for extended wear comfort, and the flexible boom microphone ensures optimal positioning for clear voice transmission.
