Sennheiser MD21 Dynamic Microphone test

Sennheiser MD21 Microphone test


The studio has 2 vintage Sennheiser MD21’s in it’s mic locker. We have made some quick and dirty drum recordings in the studio to demonstrate how the Sennheiser MD21 sounds in a few setups.

Sennheiser MD21‘s are know first and foremost as reporter microphones. These microphones have been around for ages, since the 1950’s and are built to this day. The studio’s version come from the 1960’s.
The Sennheiser MD21 is a omni directional dynamic microphone, which is a bit more rare. Usually you’ll find cardoid or supercardoid dynamic mics. These omni directional microphones record sound equal on all sides in comparison to cardoid which mainly records from the front. Due to it’s construction, the MD21 has a high frequency roll off for sound which comes from the back. This is because the capsule of the mic point forward ( front adress) in comparison to a lot of omni mics which are side adress.

Another charactaristic of omnidirectional mics is the absence of the promixity effect. That means the low end doesn’t get boosted if the soundsource comes closer to the mic. Most used application in the white noise studio studio for the mics is roommic or tom mic. I almost always use them for drum rooms.


I used 3 setups for testing ( don’t pay attention to my sloppy drumming here too much)

First as roommic. Both mics are placed in a XY configuration. Due to the high end roll off it works well in this config.
The second is close micking. First part in snare, second on a slightly detuned tom.
The third method is as in an  A/B configuration above the drums’ cymbals, at about 1,5 meter of the snare.
