AKG CM311 Reference Headworn Condenser Microphone with 3-Pin Mini, XLR Connector

Designed for demanding live-sound, broadcast and monitoring environments, the AKG by Harman CM311 reference headworn condenser microphone gives performers and technicians the confidence of clear, distortion-free vocal pickup even at high SPL. The CM311 combines AKG’s Differoid® differential cardioid technology with a condenser capsule and internal shock mount to dramatically reduce stage and monitor bleed—providing up to 12 dB more gain-before-feedback and a tighter house mix. With a focused 50 Hz–17 kHz frequency response and low 75 ohm impedance, it reproduces voice with natural warmth and intelligibility for presentations, theater, touring and security/monitoring duties. The L version’s professional mini-XLR connector plugs directly into AKG wireless body-pack transmitters for quick setup and reliable connectivity. Built for long sessions, the lightweight, adjustable headband keeps talent comfortable while resisting wear from touring and active use. Ideal for sound reinforcement, assisted listening, surveillance staff communications and live broadcast, the CM311 delivers pro-grade performance where clarity and isolation matter most. Add the CM311 to your kit for dependable, feedback-resistant vocal capture on stage, in venues or in security and monitoring operations.
