AKG CM311 XLR Reference Head-Worn Condenser Microphone

For live performers and AV professionals who demand clear, feedback-resistant vocal pickup, the AKG by Harman CM311 head-worn condenser microphone delivers pro-level performance and rugged reliability. Built around AKG's Differoid differential cardioid pickup, the CM311 provides up to 12dB more gain before feedback so front-of-house mixes stay clean and intelligible even near monitors. The electret condenser capsule produces full, distortion-free audio across a useful 50Hz–17kHz range, while the 75-ohm XLR output and dual power options (9V battery or phantom) make system integration fast and flexible. The lightweight, adjustable headband and internal shock mount reduce handling and body noise so talent can move freely on stage, in broadcast, or during presentations. Beyond live sound, the CM311 is also well suited for AV installations, monitoring, security and surveillance setups that require discreet, high-fidelity vocal capture. Backed by a rugged molded case and a 3-year limited warranty, it’s a practical choice for touring, houses of worship, corporate events and security monitoring.
