The DPA Microphones 4266 CORE Omni Flex Headset Mic combines the legendary sound of the 4066 Omnidirectional Capsule with a lightweight and flexible headset system. This condenser headset mic is easy and fast to adjust, and it offers clean and transparent sound quality with lots of headroom. The capsule itself is the same type as the 4066 but is attached to an interchangeable boom arm.

Like all the microphones in the range, the 4266 Omnidirectional 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 Headset variant sits more securely around the head and is ideal for active performance situations where the person wearing the headset won’t feel the presence of a microphone. This headset mic is ergonomically designed to fit comfortably and easily and can be adjusted to fit any ear size. At the same time, it mounts securely and is hardly visible. By rotating the boom and the earhook, the microphone can be easily used on either the left or the right ear. The connector splits the cable from the microphone boom allowing you to swap broken cables and/or wireless connectors quickly.

The boom length on this headset mic is 110 mm (4.3 in), the standard choice for most users.

IP58 Certified
All CORE by DPA technology microphones are IP58 certified. This durability is achieved through several defense mechanisms:

• Water-repellant nano-coating of the cover and housing
• Hermetic sealing of the sensitive amplifier at the core of the mic
• Dual gold plating of the diaphragm
