Help choosing a headset microphone

My boss and I are trying to find a headset microphone of the highest quality that would be suitable for a one-time radio show recording, but that would also be good for use in dictation after that. Others we have talked to have recommended the Crown CM311A.

Reply: The Crown CM-311A is designed more for live music performance. The microphone is used directly in front of the mouth with lips touching the foam grille.

I think a better choice for radio and dictation would be the Crown CM-312A. It is a miniature mic in which the boom places the mic off to the side of the mouth. It’s a very clear sounding microphone. If it sounds too bright, you could turn down the high-frequency EQ at 10 kHz in your recording software.

Neither mic includes a headphone, but you could wear a headphone over the mic.

The link below is for a mic-to-USB adapter with phantom power -- the MXL Mic Mate. You’d plug it between the mic’s XLR output connector and your computer.
