Sennheiser MKE Essential Omni Black Lavalier Microphone

Pro Vocal Clarity for Live Stage & Broadcast: Sennheiser MKE Essential Omni-Black

The Sennheiser MKE Essential Omni-Black bridges the gap between everyday lapel mics and high-end theatrical microphones. Designed for live theater, musical performances, television broadcasting, and corporate presentations, this sub-miniature condenser microphone offers professional vocal presence at an accessible price point.

Powered by Sennheiser’s refined KE 4 condenser capsule—a direct descendant of the legendary MKE 2—the MKE Essential Omni captures warm, articulate, and uncolored vocal dynamics across a full 20 Hz to 20,000 Hz frequency range. Its omnidirectional pickup pattern ensures smooth, uniform voice capture even when the performer moves their head or turns away from the mic axis. Featuring a patented moisture-resistant umbrella membrane to guard against stage sweat and makeup, this lavalier is engineered for rigorous live production demands.
