Sennheiser ME 4 Cardioid Lavalier Microphone

High Speech Intelligibility & Ambient Rejection: Sennheiser ME 4

The Sennheiser ME 4 is an industry-standard sub-miniature clip-on cardioid lapel microphone tailored for public speakers, broadcast journalists, theater performers, and corporate presenters who require clear, focused voice pickup in noisy environments.

Unlike omnidirectional lavaliers, the ME 4 utilizes a directional cardioid polar pattern to isolate the speaker’s voice while rejecting room reflections, background chatter, and stage monitors. Powered directly by Sennheiser wireless bodypack transmitters via a robust, locking 3.5 mm mini-jack, it offers effortless integration. Available now in our Sennheiser pro audio store catalog, this lapel mic delivers broadcast-quality vocal reproduction with maximum immunity to acoustic feedback.

Key Features & Pro-Level Advantages

• Cardioid Pickup Pattern: Provides exceptional off-axis sound rejection and high gain-before-feedback when operating near loudspeakers or in loud auditoriums.
• Speech-Optimized Frequency Curve (50 Hz – 18 kHz): Captures full, articulate vocal detail while attenuating unnecessary low-frequency rumble and wind noise.
• High Sound Pressure Level Handling (120 dB SPL): Effortlessly manages loud vocal dynamics without clipping or acoustic distortion.
• Locking 3.5 mm Mini-Jack Connector: Ensures a secure, noise-free connection to Sennheiser wireless bodypack transmitters and compatible portable recorders.
• Discreet & Lightweight Design: Compact micro-housing mounts effortlessly to ties, lapels, collars, and dresses using the included clothing clip.
• Integrated Metal Grille: Protects the internal electret element from physical impact and moisture.
