Sennheiser

MM 445

Dynamic · Supercardioid · 40–20,000 Hz

  • The supercardioid wireless capsule of the top Sennheiser dynamic range — the MD 445 with a transmitter thread.
  • Tighter than the MM 435 and 5 g lighter, for singers working in front of wedges.

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 MM 445 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 tierPremium
Introduced— not recorded

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”.

MM 445 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 MM 445’s for the same live job, with the reasons. It says nothing about how they sound.
