Sennheiser
MK 4
Large-diaphragm condenser · Cardioid · 20–20,000 Hz
- A one-inch true condenser at 10 dB(A) self-noise — a studio noise floor in a microphone that turns up on stages for grand piano and choir.
- 485 g and no pad or filter on the body: everything is done at the desk.
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 MK 4 yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for cardioid. It illustrates the pattern type — it is not a measurement of this individual model.

What it gets used for
- FOH vocal
- Acoustic instrument
- Choir / ensemble
- Overhead
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”.
MK 4 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 MK 4’s for the same live job, with the reasons. It says nothing about how they sound.
