DPA 4466-OP-R-F90 Headset Condenser Microphone

DPA 4466 CORE+ Omnidirectional Headset Microphone — Broadcast-Grade Sound in a Tour-Ready Frame

The DPA 4466 CORE+ Omnidirectional Headset Microphone is a flagship headworn solution built around DPA's renowned 5 mm capsule platform and the brand's award-winning refine headset frame. Designed for theatre, broadcast, house of worship and conferencing, this model delivers the natural, open sound that has made DPA miniature microphones a standard on West End stages. CORE+ amplifier technology neutralizes distortion across the entire dynamic range, so presenters and vocalists get clean, transparent audio even when pushing the mic hard. The 4466-OP-R-F90 ships in beige with the MicroLock connector, ready to pair with wireless bodypacks via separately available adapters.

CORE+ Amplifier, MicroLock Connector and a Modular Refine Headset

What separates this headset from entry-level options is the combination of three flagship technologies. CORE+ takes the original CORE amplifier further, eliminating distortion artifacts completely rather than just suppressing them, which translates to unheard levels of openness in a miniature capsule. The MicroLock connector is a secure, wear-resistant locking system that is fully backwards compatible with the existing MicroDot ecosystem. The refine headset frame is a Red Dot award-winning design with a 3-point ear grip, a 2-way adjustable boom with anti-rotate locking, and a 90° cable management system.

Capsule and Audio Performance — Natural Sound with High Headroom

The capsule and audio chain are tuned for natural speech and vocal reproduction, with a forgiving omnidirectional pickup pattern that keeps level consistent even when the wearer turns their head. CORE+ extends usable headroom well beyond standard speech levels.

• Polar Pattern: Omnidirectional — consistent off-axis response, reduced plosives and handling noise
• Frequency Range: 20 Hz – 20 kHz with a +3 dB soft boost between 8 kHz and 20 kHz from the pre-fitted grid
• Maximum SPL: 144 dB (10% THD) — handles loud vocalists and stage monitors without breakup

Sensitivity and Dynamic Range — Clean Signal in Demanding Environments

Sensitivity and self-noise figures place this headset firmly in broadcast territory. The combination of low equivalent noise and wide dynamic range makes the 4466 CORE+ equally at home in a quiet studio interview or a high-SPL concert stage.

• Sensitivity: 6 mV/Pa (-44 dB re 1 V/Pa) — strong output level for clean wireless transmission
• Dynamic Range: 111 dB (A-weighted) — wide usable range from whisper to shout
• Equivalent Noise Level: 26 dB (A-weighted) — low self-noise for critical speech capture

Headset Frame, Cable and Power — Built for Daily Touring Use

The physical design is engineered for long wear and daily touring. A one-size-fits-all stainless steel frame with a Physical Vapor Deposition (PVD) coating keeps the headset lightweight, glare-resistant and IP58-certified against dust and moisture. DPA reinforces the cable with a Kevlar inner core and routes it through a 90° guide that protects it from stress during boom movement.

• Capsule Diameter: 5.4 mm — discreet on-camera profile
• Cable Length: 1.3 m with 1.6 mm diameter and Kevlar core — rugged enough for daily handling
• Operating Voltage: 5 – 50 V — compatible with wireless bodypack plug-in power and phantom power
• Weight: 12 g (with cable) — light enough for multi-hour wear

Who the 4466 CORE+ Is Built For

The 4466 CORE+ is the right choice for theatre sound designers, broadcast audio engineers, house of worship technical directors and corporate AV teams who need a headworn mic that disappears on camera yet still delivers flagship-grade audio. Presenters benefit from the forgiving omnidirectional pickup, which keeps level consistent as they turn their head. Touring vocalists rely on the 3-point grip and PVD-coated frame to stay locked in place during energetic performances, while the modular boom and replaceable cable keep service costs down. The MicroLock connector and broad adapter ecosystem make this headset a flexible addition to rental houses running mixed-brand wireless systems.

DPA and the Refine Headset Platform

DPA Microphones built its reputation on miniature condenser capsules trusted by theatre, broadcast and live sound professionals. The 4466 CORE+ brings together two flagship elements: the proven 5 mm capsule platform from the long-running 4066 and 4266 series, and the refine headset frame first introduced on the 6066 sub-miniature. The refine design earned a Red Dot award for its 3-point grip, modular boom and PVD-coated stainless steel construction, and the 4466 boom is interchangeable with other refine-platform headsets including the 4488 directional and the 6066 sub-miniature.
