Sony ECM-678

For superior sound quality, choose the ECM-678. It delivers superior sensitivity of -28 dB (0dB=1V/Pa) and extremely low inherent noise of less than 16 dB SPL. This microphone balances the need for a compact size with its ability to deliver excellent performance. The result is a highly directional microphone that is only 250 mm in length.
