AKG 6000H50950 CM311 Head-Worn Condenser Microphone

The AKG CM311 is engineered specifically for the realities of live touring — loud stages, dense monitor mixes, and performers who move. Its Differoid noise-cancelling technology is not a marketing softening of a standard cardioid; it is a differential pressure design that actively works against off-axis pressure waves, meaning the signal arriving at the capsule from ambient sources is acoustically cancelled before it enters the electronics. The result is a head-worn microphone that sounds closer to a well-placed handheld than anything else in the headset category. With a 78 dB SNR and self-noise of 26 dB, the CM311 resolves vocal texture and consonant articulation cleanly — critical when intelligibility is non-negotiable in a theatrical or high-energy live event context.

The construction reflects professional touring demands. Aluminum and plastic materials keep weight low while providing the durability a microphone needs to survive costume changes, rain, and backstage handling. The internal shock mount decouples the capsule from the headband mechanically, so footfalls and movement artifacts stay out of the signal chain. The headband's flexibility allows a tight, consistent fit across performers — and consistency of capsule placement is what keeps your gain-before-feedback margin where it needs to be show after show. Available in multiple connector formats for wireless compatibility, the CM311 integrates cleanly into professional wireless systems without adapter compromises.
