DPA Microphones MMB4188-DP-FS1-L 4188 CORE+ Directional Miniature Mic (Beige)

Cardioid Boom Replacement Microphone for Headsets and Earsets

The DPA MMB4188-DP-FS1-L is a high-performance cardioid microphone boom designed as a direct replacement for DPA 4188 headset and earset systems. Built with DPA's CORE+ amplifier technology, this boom delivers professional-grade vocal pickup with minimal distortion, even under high sound pressure levels. Whether you're working in live theater, houses of worship, or broadcast studios, this microphone boom provides the pristine clarity and reliable durability needed for mission-critical speech and vocal applications.

Clean Audio Reproduction with CORE+ Technology

At the heart of the MMB4188 is a pre-polarized condenser capsule with CORE+ circuitry. This technology extends the usable dynamic range of the microphone while keeping distortion under 1% at SPLs up to 137 dB. With a smooth frequency response and soft presence boost from 8 to 20 kHz, it captures the human voice with striking detail and natural tone. It's ideal for users needing a tight, focused cardioid pattern that maintains clarity in complex acoustic environments.

Directional Cardioid Pickup Reduces Feedback and Ambient Noise

The cardioid polar pattern of the 4188 boom is engineered to capture only what’s in front of it—your voice—while rejecting off-axis sounds like nearby instruments or audience noise. This makes it a smart choice for amplified environments or stages with multiple microphones, where bleed and feedback are common concerns. With the proper orientation, this mic helps preserve speech intelligibility while minimizing unwanted acoustic interference.

Built for Discreet and Flexible Mounting Options

With its slim 120 mm boom and beige finish, the MMB4188 is designed to blend seamlessly into a performer's appearance. The boom arm can be positioned on either the left or right side of the face, ensuring a customizable fit based on the user's needs. It pairs with compatible DPA headset and earset frames, making it quick and easy to replace a damaged boom without needing to swap out the entire headset.

Engineered for Moisture Resistance and Durability

Stage environments are often harsh, with sweat, humidity, and dust presenting daily challenges. The MMB4188 is IP58-certified for moisture and dust resistance, ensuring long-term reliability even in hot and humid conditions. Its robust construction includes a double-vent protection system and Kevlar-reinforced cable design, offering confidence in the field where consistency is non-negotiable.

Precision Performance for Voice Applications

Whether used in live presentations, theater productions, or professional recordings, the DPA MMB4188 offers an excellent balance of performance and subtlety. With a dynamic range of 111 dB and a max SPL of 144 dB, it handles everything from soft spoken lines to intense vocal performances with equal precision. Its lightweight design adds no noticeable weight to the headset, keeping performers comfortable throughout extended sessions.
