This Collins MM-2 Head Set Microphone, is New in the Original Box!
I opened the foil pack to inspect and photograph the headset.
The Collins MM-2 is a micropohone boomset. The frequency response is 100 to 7000 Hz and has an output level of -50 dB. The MM-2 is equipped with both mike and phone plugs. It weighs only 3.5 ounces.
This Microphone is a great match for most Collins Vintage Transceivers.
This is an excellent collector item!
