QA22 Dual Ear Headworn Microphone

The QA22 was developed for users who enjoy the extra stability and comfort that a dual ear microphone system offers, and delivers superior audio quality and high end performance from the same European designed 2.5mm capsule used in our DA12 and DA04 microphones. The QA22 features total flexibility in headband and boom arm adjustment for accommodating a wide variety of head sizes and jaw lines. Pivoting ear cushions allow for easy mic boom arm placement on either side of the face. Perfect for applications requiring minimum visual discretion and freedom of movement such as theatre performers, singers, sportscasters, on-air or video talent, church pastors, aerobics instructers, presenters, boardroom use, and more. The ear cushions can be positioned for flat storage in its zip pouch.
