The d:fine 88 Directional Headset Microphone combines the legendary sound of the 4088 Directional Capsule with the lightweight and flexible d:fine Headset system. Staying true to the DPA legacy, d:fine offers accurate and natural voice intelligibility and very high-SPL capabilities users can both speak and sing into the mic with no hint of distortion.
Like all of the microphones in the range, the d:fine 88 Directional Headset Microphone offers accurate, natural voice intelligibility and very high SPL capabilities. Users can both speak and sing into the mic with no hint of distortion. The microphone capsule is also optimized for low distortion as well as humidity resistance.

The d:fine 88 Directional Headset Microphone is available with single- or dual-ear mounts. Single-ear mount variants are the quickest to put on and often the best choice when miking needs to be fast and easy. Dual-ear mount variants sit more securely around the head and are ideal for active performance situations.
