Like most of the MD-Range of mics from Sennheiser, these sound and feel a bit more like handheld condensors than dynamics; the output is powerful, present and glossy-smooth.
The supercardioid pattern neodymium diaphragm has an extremely smooth yet immediately apparent upward HF shelving tilt, as well as a bit of a LF “bump” that turns into an immensely-pleasing LF push as proximity effect becomes apparent on close-mic’ing.
A great selection for both male and female vocal sources, this mic would also perform well on percussive instruments, string and / or bowed instruments, or other instruments where additional gain is needed, but condensors aren’t available, or would be hard to manage due to high stage noise, etc.
