- DPA 4266 CORE+ earset
Description
The 4266 Omnidirectional earset Microphone combines the legendary sound of the 4066 Omnidirectional Capsule with a lightweight and flexible earset 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 earset 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 earset sits securely around the head and are ideal for active performance situations where the person wearing the earset won’t feel the presence of the microphone. It is ergonomically designed to fit comfortably and easily. This mic adjusts to fit any ear size and head shape while at the same time it mounts securely and is hardly visible. By rotating the boom and the ear hook, 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.
FEATURES:
- Pristine audio quality
- Lightweight and flexible
- Easy mounting to the left or right
- Minimal visual impact
- Resistant to humidity
- Flexible adapter system fits most professional wireless systems
