Water and Perspiration Resistant Omnidirectional Headworn Microphone with 3-Pin Mini XLR Connector


for theater and broadcast applications

The HC577L is an extremely small reference head-worn microphone, designed for on-stage use. The microphone uses a CK77 omnidirectional transducer that has been an industry standard for lavaliere capsules for years and ensures superior audio performance. A patented body design protects the microphone from moisture and perspiration. The capsule uses the signal of two vertical diaphragms mounted back to back, mixed out of phase to cancel out mechanical and cable noise.

The HC577L provides a professional three-pin mini XLR connector that fits the body-pack transmitters of all AKG wireless microphone systems.
