Sennheiser
e 904
Dynamic · Cardioid · 40–18,000 Hz · a rider regular
- Sennheiser dropped prototypes onto steel plates from 2.5 m during development; the rim clamp is the part that gives first, not the capsule.
- 125 g on a clamp — twice the weight of an e 604, with a capsule that reaches 18 kHz.
Frequency response
No response curve yet.
MicSense only draws a curve traced from a graph the manufacturer actually publishes — it never estimates one from the microphone’s class. Sennheiser publishes figures for the e 904 but no response graph, so the numbers are in the spec table below and the chart stays empty.
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
- Toms
- Snare top
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”.
Compare it against the alternatives.
MicSense lets you put up to four microphones side by side — spec table, overlaid response curves and polar diagrams on one screen. Free with a free Squaresmile account.
