AKG EC81 MD Lightweight Cardioid Ear-Hook Microphone

The AKG 3242Z00010 is a discreet ear-hook microphone that carries the EC81 MD name and brings studio-grade clarity to live performance, broadcast, and conference settings. It uses a cardioid capsule that focuses on the speaker’s voice while rejecting sound from the sides, so dialogue or vocals remain clear even in busy environments.

Engineers will appreciate the wide 20 Hz to 20 kHz frequency response, which captures the subtle lows of spoken word as well as the bright harmonics of a singer or acoustic instrument. A sensitivity of 13 mV per Pascal and a signal-to-noise ratio of 57 dB-A mean you can run lower preamp gain without losing detail, keeping noise under control on quiet stages or in the studio.

Comfort and reliability are built in. The flexible ear-hook molds gently to either ear, and the boom length adjusts so you can place the capsule exactly where it sounds best. At just 7.6 g including its cable, the microphone feels almost weightless, letting performers move naturally through long rehearsals, keynote sessions, or worship services without distraction.

Because the microphone operates on 3 to 10 volts and presents a 35.5 mW impedance, it integrates smoothly with most bodypack transmitters, portable recorders, and wired adapters that supply plug-in power. The rugged yet low-profile design makes it a smart choice for theater companies that rotate casts, touring musicians who need consistent sound night after night, and corporate AV teams who demand quick, repeatable setups.
