DPA Microphones 4066-OP-A-B34-LH-S CORE+ Omnidirectional Headset Microphone (Small, Black)

Premium Omnidirectional Headset Microphone for Professional Applications
The DPA 4066 CORE+ Omnidirectional Headset Microphone is engineered for professional users in broadcast, theater, house of worship, and conference settings. This small, black headset provides a secure, comfortable fit with a lightweight dual-ear design, ensuring stability and freedom of movement. Its omnidirectional pickup pattern captures natural, clear sound, making it ideal for speech and vocal performances in high-pressure environments.

CORE+ Technology for Exceptional Audio Quality
Featuring DPA’s CORE+ technology, this microphone delivers an extended dynamic range and significantly reduces distortion, even at high sound pressure levels. With a maximum SPL handling of 144 dB and less than 1% distortion at 134 dB SPL RMS, it ensures crystal-clear sound reproduction without unwanted artifacts. Whether used in a quiet boardroom or a live theater performance, the 4066 CORE+ consistently provides outstanding audio clarity.

Secure and Comfortable Dual-Ear Design
Designed for presenters and performers who require a stable and unobtrusive microphone, the 4066 CORE+ headset offers a dual-ear frame that sits snugly yet comfortably on the user’s head. The adjustable boom allows for left- or right-side mounting, ensuring optimal positioning for clear sound capture. Unlike traditional lavalier microphones, this headset stays in place and provides consistent audio, even with active movement.

MicroLock Connector with Locking 3.5mm Adapter for Sennheiser Systems
This model of the 4066 CORE+ is equipped with a MicroLock connector and a locking 3.5mm adapter, making it compatible with Sennheiser wireless transmitters, including the Evolution (ew), XSW-D, and SpeechLine (SL) series. The MicroLock system offers a secure and wear-resistant connection, preventing accidental disconnection. Its modular design allows users to swap adapters, ensuring compatibility with multiple wireless systems.

Moisture-Resistant and Built for Durability
Engineered to withstand demanding professional use, the 4066 CORE+ is IP58-certified for dust and moisture resistance. A double-vent protection system, reinforced Kevlar cable, and water-resistant materials make it an excellent choice for high-humidity environments and physically active performances. Whether used on stage, in fitness instruction, or during outdoor events, this microphone is built to last.

Interchangeable Boost Grids for Customized Sound
To accommodate different sound sources and placement preferences, the 4066 CORE+ includes two interchangeable capsule-protection grids. The Soft-Boost Grid provides a subtle 3 dB lift from 8 to 20 kHz, while the High-Boost Grid enhances frequencies around 12 kHz by 10 dB. These options allow users to fine-tune the microphone’s response for maximum clarity and detail.

Consistent Sound Pickup with an Omnidirectional Pattern
The omnidirectional pickup pattern captures sound evenly from all directions, ensuring consistent volume levels and natural tonal balance. This feature minimizes handling noise, reduces plosive interference, and allows for smooth transitions even when the speaker turns their head. The result is clear, intelligible audio that remains consistent across different speaking styles and environments.
