DPA 4266 CORE Omni Flex Headset and Earset Microphone

Product overview

The DPA 4266 CORE is an omnidirectional flex headset and earset microphone that combines the legendary sound of the 4066 Omnidirectional Capsule with a lightweight and flexible headset system.

This condenser microphone is easy and fast to adjust, and it offers clean and transparent sound quality with lots of headroom. The capsule is the same type as the 4066, attached to an interchangeable boom arm. It gives accurate, natural voice intelligibility and very high SPL capability, so the wearer can both speak and sing into it with no hint of distortion.

The CORE generation delivers a typical dynamic range of 111 dB and stays below 1 % distortion up to 134 dB SPL RMS. The 4266 CORE uses the MicroDot connector and is also offered terminated in 3-pin LEMO, TA4F Mini-XLR or Mini-Jack, in black, brown or beige.

The 4266 sits securely and is ergonomically designed to fit comfortably and easily, adjusting to any ear size and head shape while staying hardly visible. By rotating the boom and the ear hook it can be worn on the left or the right ear, and the connector splits the cable from the boom so a damaged cable or wireless connector can be swapped quickly. It is available as a two-ear headset or a one-ear earset, with a 110 mm or 90 mm boom.
