DPA 4066 CORE+ Omni Headset Mic, Beige, TA4F Mini-XLR

The DPA 4066 CORE+ Omnidirectional Headset Microphone is a premium, ultra-discreet headset solution that delivers pristine, broadcast-ready audio with exceptional headroom and reliability. Finished in beige and fitted with a TA4F mini-XLR connector, it is ideal for use with compatible wireless systems in theatre, broadcast, corporate presentations, houses of worship and live events where natural, intelligible speech is essential.

Built around DPA’s renowned 5.4 mm pre-polarised condenser capsule, the 4066 CORE+ offers a clean, transparent sound signature with a huge dynamic range and extremely low distortion. The updated CORE+ amplifier technology keeps your signal smooth and consistent across the entire level range, while the robust headset design and MicroLock connector ensure dependable performance in demanding professional environments.

With an omnidirectional pickup pattern, the 4066 captures speech evenly and naturally, even with head movement, making it a long-standing favourite on Broadway stages, in broadcast studios and in auditoriums worldwide. Its lightweight construction, flexible boom and neutral beige finish help it sit comfortably and unobtrusively on the performer, allowing the audience to focus on the performance, not the microphone.

Engineered for real-world use, the 4066 CORE+ maintains clarity at very high sound pressure levels, offers low self-noise for quieter sources and can be run over long cable distances when used with the appropriate DPA adapter. For professionals who need a headset microphone that simply works day in, day out, this is a trusted, industry-standard choice.

CORE+ Clarity and Headroom

DPA’s CORE+ technology refines the internal amplifier of the 4066 capsule to minimise distortion across the entire dynamic range. This means your signal stays clean and detailed from the quietest whisper up to extremely loud speech or vocals, reducing the risk of harshness or breakup and giving engineers more freedom to work with dynamics in the mix.

Natural Omnidirectional Pickup

The omnidirectional polar pattern provides an open, natural sound that remains consistent even when the wearer turns their head. This makes it ideal for presenters, actors and performers who move freely on stage, helping to maintain intelligibility and tonal balance without constant mic repositioning.

Discreet, Comfortable Headset Design

Weighing just 14 g including cable and connector, the 4066 CORE+ is designed to be worn for long periods without fatigue. The slim 5.4 mm capsule, flexible boom and beige finish help it blend with skin tones and stage make-up, keeping the focus on the performance while still delivering full-range, studio-quality sound.

TA4F MicroLock Connectivity

This version of the 4066 CORE+ is fitted with a TA4F mini-XLR connector featuring DPA’s MicroLock system for a secure, dependable connection to compatible wireless transmitters. MicroLock gives you reassuring mechanical stability and easy, repeatable attachment, reducing the risk of accidental disconnection during demanding live use.
