Sennheiser E904

A close-miking microphone designed for drums, at the heart of the Evolution series

The Sennheiser e 904 is a dynamic close microphone designed to meet the specific demands of drums: limited space, high sound pressure levels, vibrations, and the need for immediate sound. Its compact size allows it to be positioned where the sound is most interesting (close to the point of impact), while remaining discreet. With its cardioid pattern, it helps focus the pickup on the targeted drum shell, a real advantage when the stage is crowded and sources are close together.

For which uses and musicians?

The e 904 is aimed at drummers, backliners, front-of-house engineers, and home studio users who want a quick-to-set-up, coherent, and effective sound capture on toms, snare drum, and percussion. It is particularly relevant if you are looking for a microphone that "cuts through immediately" in the mix: clear attacks, solid low end, and presence that facilitates equalization. In concert, its compactness also reduces the risk of stick hits and simplifies stage changes.

Precise sound and hassle-free setup

Cardioid pattern: focus on the drum shell

Thanks to its cardioid pattern, the e 904 favors the source placed in front of the capsule while reducing side pickup. The result: better separation between kit elements, useful for keeping toms clear and the snare well defined, even with monitors and amplifiers nearby.

Fast dynamics: attacks, transients, and impact

Designed for percussion, this dynamic microphone stands out with a very responsive transient response. It highlights the stick attack and the "punch" of the drum shell, helping to achieve a modern, energetic sound that is quickly usable without relying on heavy processing.

Compact size + included clip: millimeter-precise placement

Its short body facilitates mounting on the snare or toms, very close to the drumhead, without cluttering the playing space. The supplied MZH 604 drum clip allows for quick and stable installation, ideal for quick soundchecks and tours.

Hum-compensating coil: cleaner capture

The e 904 incorporates a hum-compensating coil, designed to limit unwanted noise related to often electrically noisy environments (lighting, power supplies, power strips). A detail that enhances reliability in real conditions.

Ready to go: pouch and accessories

Delivered with its pouch and user manual, the e 904 is easy to transport and naturally integrates into a multi-mic drum setup, both in the studio and live.
