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.

The smooth and elegant design of the 4088 makes it the most invisible headworn cardioid microphone today. Sound quality, visual elegance and versatility go hand in hand to transform every show into the performance of a lifetime. The capsule is a pre-polarized first order pressure gradient transducer, hidden in a small and lightweight housing with dimensions just slightly larger than our omni capsules.

The mechanical design is based on the proven quality of the 4066 headset microphone. The headset mount is exactly the same; the boom however is 3 centimeters longer in order to meet the need for placement at the corner of the mouth. The flexibility and stability of this construction is unique and has no equal.

Available in three colors: black, beige and brown, and also available with connector.

What is in the box:

  • Microphone (boom, headset, cable)
  • A pre-mounted pop screen
  • Five foam windscreens (similar to DUA0560)
