HMM-IC Heil Fist Mic. for Icom with electret Mic insert Fist Mic. for Icom with electret Mic insert, range 200Hz to 8kHz, The newly designed HMM brings new technology to the hand microphone. No question when you place a microphone element inside a clamshell. The result is a hollow muffled sound but Amateur Radio operators have lived with it for decades. To solve this problem, we installed a grill on the top of the microphone that detunes the internal resonance of the housing. We came up with a very special full-range microphone element with great speech articulation. The result is a phenomenal hand microphone. A very flexible but sturdy coil cable terminates as all of our headsets with 1/8” male for the microphone and a ¼” male for the PTT control. This definitely raises the bar for all hand microphones. The new Heil HMM.
