Sennheiser
e 906
Dynamic · Supercardioid · 40–18,000 Hz · a rider regular
- Flat-bodied and side-address, so it hangs over a guitar cab on its own cable with no stand — the single reason it displaced the SM57 on a lot of stages.
- A three-position presence switch on the face lets you pick bright, neutral or dark without touching the desk.
Frequency response
Redrawn from Sennheiser’s published response graph (approximate, ±2 dB) on the fixed MicSense scale — 20 Hz–20 kHz, −20 to +15 dB — so two microphones can be compared at a glance. No image is copied; it is a guide to the shape, not a measurement. Drawn for: presence switch in the middle (flat) position, dark-blue curve; 0°, 1 m. The maker’s graph (FREQUENCY RESPONSE graph, product specification p.2 (dBV, normalised to 0 dB at 1 kHz)).
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.

| Introduced | 2006 |
Price tier and “a rider regular” are MicSense’s own judgement, not the maker’s.
What it gets used for
- Guitar cab
- Snare top
- Toms
- Horn / brass
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”.
e 906 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 e 906’s for the same live job, with the reasons. It says nothing about how they sound.

sE Electronics
V7 X
- Same job: guitar cab, snare top, toms
- Same type: dynamic
- Same supercardioid pattern
- Similar published response shape (≈ 2 dB apart on average, 100 Hz–10 kHz)
- About the same output — within the datasheets’ tolerance
- End-address instead of side-address — mounts differently
-

SM57
- Same job: guitar cab, snare top, toms
- Same type: dynamic
- Similar published response shape (≈ 1.4 dB apart on average, 100 Hz–10 kHz)
- About the same output — within the datasheets’ tolerance
- Cardioid instead of supercardioid — deepest rejection at 180°, not ±126°: check where the wedge sits
- End-address instead of side-address — mounts differently

Sennheiser
e 609 Silver
- Same job: guitar cab, horn / brass
- Same type: dynamic
- Same supercardioid pattern
- Same form: side-address
- Similar published response shape (≈ 2.1 dB apart on average, 100 Hz–10 kHz)
- ≈ 3 dB less output — add about 3 dB gain
