Beyerdynamic MPR 210 2010s - Black

Bought this pre-owned. I imagine it was discarded from some conference table in corporate America. It's a little dinged up I tried to capture that in the photos but it works well. I picked this up to experiment with a microphone line array. Works great for picking up voices in front of it from many angles /positions while rejecting noise from off angles.

Here's the description from the manufacturer:

beyerdynamic's MPR 210 B, a modern desktop microphone, is ideal for discussions, tele/video conferencing, and announcements. It's equipped with Revoluto technology and integrated microphone capsules, all of which provide a so-called "corridor" characteristic which is designed to ensure a wide pickup range with good voice quality. Within this range the speaker can move about freely, i.e. he/she can stand up or sit down, move his/her head, and move towards or away from the microphone with minimum quality variation.
