Sennheiser
MMD 845
Dynamic · Supercardioid · 80–18,000 Hz
- The supercardioid capsule of the 800 wireless range — the e 845 head, for a singer who stands in their own wedge.
- About 2.4 dB quieter than the cardioid MMD 835 it sits next to in the case (1.6 against 2.1 mV/Pa).
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 MMD 845 yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for supercardioid. It illustrates the pattern type — it is not a measurement of this individual model.

Price tier and “a rider regular” are MicSense’s own judgement, not the maker’s.
What it gets used for
- Wireless handheld capsule
- FOH vocal
- Monitor vocal
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”.
MMD 845 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 MMD 845’s for the same live job, with the reasons. It says nothing about how they sound.
