*OPEN BOX* Crown CM311A XLR Reference Head-worn Microphone

This listing is for an open box Crown CM311A with an XLR connector. We purchased it new for a client, but they ended up not needing it. The mic has only been used to test it to make sure it works.  Includes everything in the pictures.

Info from the manufacturer:

The CM311 reference head-worn condenser microphone is designed for touring and live-sound applications. It sounds like the best handheld microphones – full, clear and distortion-free, even with the loudest singers.

Differoid stands for differential cardioid, which cancels ambient noise from floor monitors, crowds and other sources. Controlled field tests show that the Differoid provides up to 12dB more gain before feedback than conventional cardioid microphones. Many users of CM311 say that their house mix is better because the mic’s isolation is nearly complete.
