The field-replaceable cushioned ear pads also come with removable cotton covers that can be easily removed for washing. The 6' coiled cable terminates in a 1/8" mono plug for the microphone, and a stereo 1/8" plug for headphone speaker
connection. A 1/8" to 1/4" adapter is also supplied. The PRO SET ELITE works with all Heil AD-1 adapter cables, which mate with just about every type of amateur radio transceiver.

Pro Set Elite - iC contains the specially designed high performance electret condenser which was designed for low level mic inputs used in many iCOM amateur radio transceivers. The -3dB points are fixed at 80Hz and 12.5kHz. The iC element
requires +5Volts DC phantom power, which all iCOM rigs provide.
