The Countryman Isomax Headset Microphone is the original Countryman head-worn microphone and a favorite for both speech and performances. The Isomax features a flexible boom for easy positioning and the sensitive capsule features a full 20Hz to 20kHz frequency response for full, clear audio reproduction.

The Isomax effectively rejects off-axis audio, minimizing feedback and residual noise. The flexible, adjustable band fits snugly and comfortably around the back of the head for concealed use on stage, during trade shows, speeches, sermons, etc.

A wide variety of colors and connections are available for use with various wireless transmitters. This version is black and features a 4-pin Hirose connector for use with *specific Audio-Technica transmitters.

Note: *This Isomax Headset features a connector that is wired specifically for use with the Audio-Technica T27, T31, T51, T200, T210, T300, T310, T1400, T2000 and T3000 transmitters only.

        Comments about Countryman Isomax Headset (Black):

        I am a Jazzercise instructor and use this mic 3-5 times per week. I bought it to go with my Audio Technica transmitter and receiver. It sounds SO much better than my original AT mic headset! It does not contact my skin so does not get soaked with sweat like my AT mic did. The sound is pretty amazing. It is lightweight and comfortable but I had to change the way I wear my hair when working out because the design hit my ponytail. So now I wear the ponytail a bit higher and clip this headset right below it. It does not stay in place without the clip. Maybe it would for someone with short hair. I was disappointed that this product did not come with a carrying case. I have to travel to my class locations and am currently using the small cardboard box that it came in.
