It's been a while since I have reevaluated my microphone. I currently use an Audiotechnica ATM73a. The boom on the mic is too small for many older adults, and the temple pads are painful. SO, I'm in the market for a good (i.e., flat response) condenser microphone for acoustics research. (there should be no other active processing of the sound.) Does anyone have a recommendation for a head-worn mic? Thanks in advance!
