d:fine FIDB10-IE1-B Single-Ear Directional Headset


Key Features

  • Pristine audio quality
  • Rejects background noise
  • Adapts to all pro wireless systems
  • Wireless System Mics
  • Wired Mic
  • TA4F


The d:fine headset is an industry leader in headpiece microphones, combining absolute pristine audio quality with unique & simple mechanical solutions. The d:fine’s ergonomic design allows for it to fit easily and seamlessly. Adjusts to fit any ear size and head shape, while mounting on either the left or right side of user.

Additionally, the d:fine directional rejects side and background noise while creating higher separation from nearby sound sources improving the gain-to-feedback ratio & adds more channel control. Preserving natural voice intelligibility, along with very high SPL capabilities, one can both speak and sing with no tone distortion. This is where the DPA d:fine is head and shoulders above its competition. Rotating boom allows microphone to move from left to right ear or to place it in optimum positioning. The mic boom also comes in a short version. Intensive protection against pop/wind noise is microphone feature as well as included windscreens. Furthermore, includes a capsule protection cap, which anchors cable to clothing and color-coded clip for easy recognition among many headsets.

A service connector splits the cable from the microphone boom and allows for quick exchange of cable lengths/colors/connectors and is valuable for servicing broken cables. Available in black, beige and brown, the DPA d:fine is delivered in a neat, professional roadworthy box with extra room for accessories like transmitters, batteries and more. The DPA accessory line includes windscreens, power supplies and adapters or cables with fixed connectors (MicroDot, 3-pin Lemo, TA4F mini XLR, Mini-jack).
