The Countryman H6 Omnidirectional Headset Microphone is one of the smallest and most discreet headset mics in the world, designed for outstanding speech clarity and nearly invisible appearance when worn. It has an omnidirectional polar pattern with a frequency response from 20 Hz to 20 kHz, delivering natural, transparent sound ideal for public speaking, presentations, and broadcasts. The microphone capsule has a diameter of just 0.1 inches (2.5 mm), virtually disappearing from view at distances over 15 feet.
