DPA Microphones 4266-OP-F-C03-LE 4266 CORE+ Omni Flex Earset Mic (Brown)

Flexible Earset Microphone for Professional Presentations and Broadcast Use

The DPA 4266 CORE+ Omnidirectional Flex Earset Microphone with a 110mm boom and 3-pin LEMO connector is designed for users who require high-fidelity voice reproduction in a low-profile, lightweight format. Whether you're addressing a live audience, appearing on camera, or performing in a theatrical production, this headset ensures crystal-clear vocal pickup with minimal visibility. Featuring DPA’s CORE+ amplifier technology and a trusted 4066 capsule, this mic delivers consistent, distortion-free performance in a format that is both comfortable and durable for extended wear.

Ergonomic One-Ear Fit with Secure, Discreet Mounting

Built for comfort, the 4266 is designed to adapt to a wide range of ear sizes and shapes. The flexible boom arm and rotating earhook provide left or right ear mounting while maintaining a barely-there profile. This makes it ideal for professionals who need a secure, quick-fit solution without drawing visual attention. The 110mm boom provides extended reach and is especially useful for capturing consistent voice pickup without adjusting placement, even during dynamic presentations or on-stage movement.

CORE+ Technology Delivers Clarity Without Distortion

Equipped with CORE+ amplifier circuitry, this microphone maintains high clarity across a broad dynamic range. It tolerates up to 134 dB SPL RMS and 137 dB SPL peak with less than 1% distortion, handling peaks of up to 144 dB with minimal degradation. This makes it a reliable choice for speech applications ranging from quiet narration to more intense live presentations. The CORE+ architecture eliminates unwanted artifacts and distortion, ensuring your voice remains clear and intelligible in any setting.

Omnidirectional Capsule Ensures Natural Sound Reproduction

The omnidirectional pickup pattern captures sound evenly from all directions, preserving a natural tone and eliminating the need for precise mic positioning. This ensures stable audio quality even if the user turns their head or moves around. With reduced sensitivity to plosives and handling noise, this mic is perfect for applications like lectures, broadcast commentary, or theatrical dialogue where consistent vocal tone and intelligibility are essential.

Compatible with Lectrosonics and Other 3-Pin LEMO Systems

This version includes a 3-pin LEMO connector, making it directly compatible with wireless transmitters from Lectrosonics (including SSM and DBu), Sennheiser SK Series, and Wisycom MTP systems. Its modular MicroLock design supports interchangeable adapters, allowing you to reconfigure your setup without replacing the microphone. This flexibility helps production professionals standardize their gear across different transmitter systems with minimal downtime or equipment cost.

Interchangeable Frequency Boost Grids for Custom Sound Shaping

Included with the 4266 are two tonal adjustment grids—Soft-Boost and High-Boost—that let users tailor the high-end response of the microphone. The Soft-Boost grid adds a gentle 3 dB presence boost in the 8–20 kHz range, while the High-Boost grid delivers a sharper 10 dB lift around 12 kHz. Made from durable anodized stainless steel, these caps can be swapped and cleaned easily to suit different environments or vocal preferences.

Durable Construction with IP58 Moisture and Dust Resistance

Built to handle demanding production environments, the 4266 features an IP58 rating, making it resistant to sweat, dust, and moisture. The rugged 4.1-foot cable is reinforced with Kevlar for long-term durability and strain relief. Whether it's used under hot stage lighting, in outdoor broadcasts, or during multi-hour performances, this mic is designed to keep up with real-world conditions.
