Where to buy

Product Description

The d:fine headset’s capsule housing has a slimmer profile than older DPA Headset mics, without compromising performance. The d:fine™ headband system is almost undetectable when in place and the mic can be mounted on just one ear if required, with the Single-Ear version available as a complete unit or by purchasing the single-ear earhook alone.

The DPA d:fine™ modular headset system will fit any ear size and head shape and is quickly and easily adjusted. In performance terms the d:fine™ stays true to the DPA philosophy of superior sonic clarity together with extreme level handling capabilities and sleek visual design.

The Omni d:fine also comes in a short boom version which is visually discrete and can be mounted in a matter of seconds, ideal when mics and packs are having to be swapped around during costume changes etc. The detachable microphone cable is terminated to a microdot connector which can be used with any of the DPA adapters depending on which wireless system is being used.
