The Sennheiser ME 4 is a compact and versatile electret condenser lavalier microphone designed for professional speech applications in broadcasting, theater, and public address. Featuring a cardioid polar pattern, it provides focused pickup of the sound source directly in front of the capsule while offering significant rejection of ambient noise and room acoustics from the sides and rear. This directionality is crucial for achieving high gain before feedback in sound reinforcement situations and for ensuring clear vocal intelligibility in noisy environments. The microphone's miniature size and neutral beige color allow for discreet concealment on clothing, making it a preferred choice for television presenters, stage performers, and conference speakers where both audio quality and visual subtlety are paramount.

The ME 4 is engineered with a smooth, tailored frequency response that emphasizes the presence range for natural-sounding speech reproduction. Its robust construction includes a durable metal grille and a flexible, strain-relieved cable that resists handling noise and cable-borne microphonics. The microphone operates on plug-in power, typically supplied by a compatible wireless bodypack transmitter or a beltpack power supply, ensuring straightforward integration into existing audio systems. Its reliability and consistent performance have made it a long-standing standard in the industry, trusted by audio engineers for critical applications where microphone failure is not an option.

This lavalier microphone is part of Sennheiser's modular MKE series, designed to work with a variety of powering modules and accessories for maximum flexibility. It is commonly used with the MZA 900 P miniature powering module or directly with wireless systems featuring the appropriate 3.5mm powering interface. The ME 4's combination of sonic accuracy, directional control, and physical durability provides a professional-grade solution for any scenario requiring discreet, high-quality vocal capture, from live stage productions to corporate video productions and broadcast news desks.
