Product Description

The DPA CORE 4166 Omnidirectional Flex Earset is an omnidirectional headset Microphone combining the linear frequency response and transparency of the DPA sound with the modular design of the Flex headband.

The CORE 4166 Earset features a single ear mount that can be mounted on the speaker’s left or right side. Available in black, brown and beige, the 4166 also features boom lengths of 40mm, 90mm or 110mm.

The omnidirectional CORE 4166 capsule provides excellent headroom with a max SPL handling before clipping of 144dB. Additionally, as with all CORE by DPA Microphones, the CORE 4166 capsule is IP58 rated for water and dust ingress and comes with a soft boost grid and five windscreens.

The DPA CORE 4166 headsets are modular in nature – the microphone boom and cable can be disconnected allowing you to switch between dual-ear and single-ear headbands. Due to the unique design of the Flex headset, the signal integrity and durability is maintained throughout the many configurations available to you.
