Sennheiser
MKE Essential Omni
Electret / lavalier · Omnidirectional · 20–20,000 Hz
- 140 dB SPL from a 16 g lavalier — enough to clip to a brass player rather than only to a presenter.
- The cost-down member of the MKE lavalier family, aimed at houses that need thirty of them rather than three.
Frequency response
No response curve yet.
MicSense only draws a curve redrawn from a graph the manufacturer publishes — it never estimates one from the microphone’s class. No published graph has been redrawn for the MKE Essential Omni yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for omnidirectional. It illustrates the pattern type — it is not a measurement of this individual model.

What it gets used for
- Theatre lav
- Broadcast
MicSense tags microphones by the job on a live stage, not by studio category — so you can filter for “kick in” or “monitor vocal” instead of working backwards from “large-diaphragm condenser”.
MKE Essential Omni alternatives: closest in published specs
Based on published specifications only — always listen at soundcheck. These are the microphones in the MicSense library whose datasheet figures sit closest to the Sennheiser MKE Essential Omni’s for the same live job, with the reasons. It says nothing about how they sound.
