DPA d:fine CORE 4088 Directional Headset Mic, Beige, MicroDot

The classic d:fine 4088 Directional Headset Microphone is the industry standard in professional headset mics. It offers an open and natural sound making it ideal for both spoken word and vocal performance applications.

It also provides excellent off-axis rejection in high-SPL situations. The microphone efficiently suppresses distant sound sources making it perfect for demanding live performance environments where background noise and feedback are concerns.

The smooth and elegant design of the d:fine 4088 Directional Headset Microphone makes it the most invisible head-worn cardioid microphone in the world. The capsule is a pre-polarized first-order pressure gradient transducer, hidden in a small and lightweight housing. The microphone can be mounted on either the right or left side.
