Like all of the microphones in the range, the d:fine? 66 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? 66 Omnidirectional 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.

Available in black, beige and brown, the d:fine? 66 has been ergonomically designed to fit comfortably and easily around the head. This mic adjusts to fit any ear size and head shape while at the same time it mounts securely and is hardly visible. By rotating the boom and the ear hook, the microphone can be easily used on either the left or right ear.

Boom lengths
Two directional boom lengths are available to accommodate different applications and head sizes: 90 mm (3.5 in), 110 mm (4.3 in).

Cables
Designed for professional use, the connector splits the cable from the microphone boom. This allows you to quickly swap broken cables and/or wireless connectors.

Flexible adapter system
The adapters for wireless systems give you flexible, simple and affordable possibilities. You are no longer bound to one wireless system. As circumstances change, you can just switch your adapter, instead of incurring the cost of a whole new microphone. And when you make the switch, you won't hear any loss or change in sound quality.

The d:fine?, d:screet? and d:vote? series of miniature microphones work with all leading wireless mic solutions, such as Lectrosonics, Sennheiser, Shure, Sony, Wisycom, Zaxcom and many more. DPA Microphones' ingenious adapter system is one of a kind in the industry. It protects your investment in fantastic sound for years to come.
