DPA Microphones 4266-OP-F-C03-LH 4266 CORE+ OmniFlex Headset Mic (Brown)

Professional Dual-Ear Headset Mic for Speech and Broadcast Clarity

The DPA 4266 CORE+ Omnidirectional Flex Headset Microphone with 110mm boom and 3-pin LEMO adapter is engineered for professionals who need consistent, crystal-clear voice pickup in a compact, reliable headset. Designed with DPA’s signature 4066 capsule and advanced CORE+ amplifier technology, this lightweight dual-ear mic delivers a rich and transparent sound profile with very low distortion—even at high volumes. Its long boom arm ensures optimal mic positioning, while the discreet brown finish blends into skin tones for stage, conference, and broadcast use.

Stable Dual-Ear Design with Ergonomic Fit for Long-Wear Comfort

The dual-ear configuration offers superior stability during active use, staying securely in place even during high-movement situations. Its flexible ear hooks and rotatable boom allow you to easily configure the mic for either the left or right ear, making it adaptable for different performers and use cases. With its ergonomic frame, the headset rests lightly and comfortably, providing long-term wearability without pressure or distraction—ideal for speakers, hosts, educators, and on-stage performers who need to focus on delivery, not gear.

High-Fidelity CORE+ Amplifier for Precision Vocal Pickup

The built-in CORE+ amplifier provides extended dynamic range, minimizing distortion across both quiet and loud vocal passages. With a tolerance of up to 134 dB SPL RMS and 137 dB SPL peak—reaching up to 144 dB SPL at 10% THD—this mic is capable of capturing intense vocal levels without introducing harshness or artifacts. Whether used in a theater setting or live TV environment, the 4266 CORE+ maintains audio integrity, ensuring speech sounds clear, intelligible, and natural.

Omnidirectional Capsule Delivers Balanced, Consistent Audio

The omnidirectional microphone element offers uniform pickup from all angles, helping to eliminate fluctuations in tone and volume caused by head movement. This pattern also reduces sensitivity to plosives and minimizes handling noise, making it especially useful for presenters and performers who need a consistent vocal output. The result is a more open, accurate representation of the voice without the need for frequent adjustment or retakes.

Compatible with Lectrosonics and Other 3-Pin LEMO Transmitters

Equipped with a MicroDot connector and 3-pin LEMO adapter, this model supports seamless integration with Lectrosonics wireless systems including the SSM and DBu, as well as transmitters from Sennheiser and Wisycom. The modular system allows you to switch connectors without replacing the entire microphone, helping reduce downtime and simplify inventory management. This flexibility makes the 4266 a practical and scalable choice for teams working across various wireless setups.

Tone Shaping Options with Interchangeable Boost Grids

The included Soft-Boost and High-Boost grids give users the ability to fine-tune the mic’s high-frequency response. The Soft-Boost grid adds 3 dB in the 8–20 kHz range for subtle vocal presence, while the High-Boost option provides a sharper 10 dB lift around 12 kHz for situations that demand more vocal brightness. These anodized stainless steel grids are easy to detach, clean, and reinstall, making them perfect for busy production environments.

Built to Last with Rugged, Moisture-Resistant Materials

Rated IP58 for dust and moisture protection, the 4266 is designed to endure the physical demands of field production, live performance, and continuous daily use. The Kevlar-reinforced 4.1' cable withstands repeated flexing and tension, reducing the risk of signal dropout or failure over time. Whether used on set or on stage, the durable construction ensures that your audio remains dependable in the toughest conditions.
