AvMike version for HamRadio
Special version with integrated mic freq.-response mode switch
The AR version of AvMike was created with the help of intensive consulting and prototype practice performed by a very experienced amateur radio guy. The amateur radio party also need headphones that are comfortable for a long time to sit, provide a very good speech audibility and accurate representation. The microphones have a close relationship to the requirements of aviation - best speech audibility and very good background noise reduction.
