Sennheiser MKE 1-ew Sub-Miniature Omnidirectional Lavalier Microphone

Ultra-Discreet Professional Audio: Sennheiser MKE 1-ew

The Sennheiser MKE 1-ew represents the peak of sub-miniature lavalier engineering. Designed specifically for musical theater, live TV broadcasting, film sets, and executive presentations, this micro-sized clip-on microphone delivers broadcast-grade acoustics while remaining virtually invisible to the audience and camera lenses.

Engineered to handle the tough physical demands of live stage performances, the MKE 1 features a sweat-resistant construction with an innovative protective umbrella housing that shields the capsule from moisture, makeup, and humidity. Its flexible, Kevlar-reinforced cable minimizes cable handling noise while providing exceptional durability against kinking and pull forces. Available now in our Sennheiser pro audio store catalog, the MKE 1-ew offers uncompromising vocal presence and pristine signal clarity.
