DPA Microphones FIO66F34-2-IE1
d:fine Omni In-Ear Broadcast Headset, 2-Ear Mount, 1-In-Ear Monitor, Beige

OUR PART #  FIO66F34-2-IE1-B


The DPA Microphones FIO66F34-2-IE1-B is a d:fine omnidirectional in-ear headset that features 2-ear mount, one in-ear monitor with hardwired 3.5 mm connector. The FIO66F34-2-IE1-B Omnidirectional Headset Microphone offers clean and transparent sound quality with lots of headroom.

The headset construction is unique. Users can detach the mic boom from the headset mount to switch it to either the left or right side and then reattach it. Humidity, often an issue in theatrical applications, is not a problem. This microphone is constructed with a double-vent protection system and a drop stopper on the microphone boom. Also, the materials inside the mic are water resistant. These design elements make it very difficult for the microphone to fail due to humidity. In addition, the headset surface is matte-gold plated and the ear hooks are covered with a silicone hose.

DPA Microphones FIO66F34-2-IE1 Features:

  • Resistant to humidity
  • Available in three colors and three sizes
  • Modular adapter system fits most professional wirelesssystems
  • Microphone and in-ear monitor integrated in one unique solution
