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. 

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 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.

“All the headset mics I'd previously used sounded very unnatural — either muffled or very thin and boxy, and feedback problems were terrible. The DPA 4088 solved all of these issues.”

 – Pete Keppler, front-of-house engineer for Katy Perry’s California Dreams tour 

Legacy or CORE – the choice is yours

The legacy d:fine™ 4088 has always been, and still is, one of the most clear, consistent and robust miniature microphones you can find on the market. It is known for working across a wide dynamic range as well as exhibiting low distortion across all SPLs. But, if you need to squeeze a little more performance out of your mics, choose CORE. The d:fine™ CORE 4088 gets a 14 dB increase in both THD and Dynamic range: 

Total harmonic distortion: < 1% THD up to 137 dB SPL peak
Dynamic range: Typ. 111 dB

CORE availability

The d:fine™ CORE 4088 Directional Headset Microphone is available in beige with either MicroDot, 3-pin LEMO, TA4F Mini-XLR or Mini-Jack termination.

In January 2018, it will also be available in brown and black with either MicroDot, 3-pin LEMO, TA4F Mini-XLR or Mini-Jack termination
