M686 is a cousin to the M629, with excellent transmit audio response from a unique cardioid unidirectional dynamic element. Compared to the M629, the M686 has a similar high end rise in the 2 to 4 kHz range, with slightly elevated higher end output useful for DXing or use with the speech processor on, with slightly less low end response while retaining an overall well-rounded audio profile. Black metal frame, squared off metal microphone hood. $69.
