DPA Microphones 4266-OP-F-C34-LH 4266 CORE+ OmniFlex Headset Mic (Brown)

Dual-Ear Headset Microphone Designed for Clear Speech in Live Production

The DPA 4266 CORE+ Omnidirectional Flex Headset Microphone with a 110mm boom and locking 3.5mm mini-jack is a professional-grade solution for presenters, broadcasters, performers, and content creators who need clear, distortion-free audio in a compact and comfortable headset. Featuring DPA’s trusted 4066 capsule and upgraded CORE+ amplifier, this lightweight dual-ear headset is built for high-performance speech reinforcement across live, studio, and broadcast applications. It connects seamlessly with Sennheiser wireless transmitters for reliable mobility on stage or on set.

Comfortable Dual-Ear Fit with Extended Boom Arm for Stability and Precision

The dual-ear frame offers a secure fit that keeps the mic in place during extended performances, active movement, or long broadcast sessions. It adjusts easily to fit a wide range of head shapes and sizes, and the 110mm boom arm ensures optimal mic positioning for consistent vocal capture. Designed to be low-profile, the brown color blends into skin tones for a discreet look on camera or on stage, while the adjustable boom and ear hooks allow left- or right-side placement based on user preference.

CORE+ Amplifier Handles Loud Sources Without Compromising Audio Clarity

Built with DPA’s advanced CORE+ amplifier, this microphone delivers detailed, transparent audio with very low distortion across the entire vocal range. It performs flawlessly up to 134 dB SPL RMS and 137 dB peak with less than 1% distortion, and can handle peaks up to 144 dB SPL at 10% distortion—making it ideal for both quiet speakers and loud performers. Whether used in a church, theater, corporate venue, or on a TV set, the 4266 maintains audio integrity in any high-pressure environment.

Omnidirectional Capsule Ensures Consistent Audio Even with Movement

The omnidirectional polar pattern captures sound evenly from all directions, providing consistent tone and volume even if the speaker turns their head. This makes it well-suited for live situations where speakers need to move freely without worrying about mic placement. The design also reduces plosives and handling noise, ensuring that speech remains clean, intelligible, and natural throughout the performance.

Locking 3.5mm Connector for Compatibility with Sennheiser Wireless Packs

This version includes a locking 3.5mm adapter, making it fully compatible with Sennheiser wireless systems such as the Evolution (ew), XSW-D, and SpeechLine (SL) series. The modular MicroDot connector allows you to quickly switch to different adapters or replace damaged cables, eliminating the need to buy a whole new microphone. This modular system provides long-term flexibility, especially for professionals working across various platforms and setups.

Interchangeable Boost Grids Allow for Tailored High-End Response

To fine-tune the mic’s frequency response, the 4266 includes two stainless steel grid caps. The Soft-Boost grid gives a subtle 3 dB lift from 8–20 kHz for added vocal presence, while the High-Boost grid adds a brighter 10 dB peak around 12 kHz for enhanced intelligibility in louder environments. These tone-shaping options give users control over how the mic responds in different venues or acoustic conditions and can be easily removed for cleaning.

Rugged Build with IP58 Certification for Reliable Use in Tough Conditions

This headset mic is designed to handle the wear and tear of professional use. With an IP58 rating, it resists dust, sweat, and moisture, while the reinforced 4.1-foot Kevlar cable is built to withstand constant bending and pulling. Whether you're in a fast-paced broadcast studio, live theater, or outdoor venue, the 4266 is engineered to perform reliably without compromise.
