The Pro Set is designed to meet the exacting standards of world-class Contest and DX operators. it is a lightweight, versatile headset designed for comfort, durability, and performance. The earpieces are full-sized, the ear pads are removable, for washing.

The speakers are 200-Ohm nominal devices, with a -3 dB point at 8000 Hz. This combination reduces hiss found in receiver audio stages. These speakers exhibit medium sensitivity but are easily driven by most rigs by turning the AF Gain control up to about 2 o’clock.

It utilizes the Heil Sound iC electret element designed to be used with ICOM radios. This element utilizes bias power in ICOM radios which addresses low-gain issues that arise when using dynamic elements. The -3dB points are fixed at 80 Hz and 12.5 kHz. The iC element requires +5 volts DC bias power, which all iCOM rigs provide. The iC adapters have no internal DC blocking capacitor so bias voltage can be passed allowing the iC electret element to operate.

Each Pro Set is equipped with a windscreen for the microphone. The windscreen does not affect the frequency response of the microphone, and it is highly effective in minimizing breath blasts while you’re speaking.
