Headset and Pick Up Microphones

DPA 4088

    • Description

    DPA 4088 is a miniature cardioid headset mic built on the finest DPA experiences in microphone design and manufacturing, providing the best sounding directional headworn microphone available today for performing talent of various sorts.
    Open, natural and reliable are the most describing words for this microphone. The high quality of the microphone itself means that you will hear the sound of the voice right away - not the microphone. In acoustically demanding live performance environments, where background noise and feedback is a concern, the 4088 will tackle these challenges with ease.
