The DPA d:fine 4088 Headworn Microphone is a cardioid headworn microphone, featuring 30-40 Ohm impedance, 144 dB SPL, and comes in black. 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-polarised first-order pressure gradient transducer, hidden in a small and lightweight housing. The microphone can be mounted on either the right or left side. The mechanical design is based on the proven quality of the classic d:fine 4066 Omnidirectional Headset Microphone. The headset mount is exactly the same; the boom however is three centimetres 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.
