Sennheiser MD 431 II Supercardioid Dynamic Microphone

Flagship Live Vocal & Broadcast Performance: Sennheiser MD 431 II

The Sennheiser MD 431 II stands among the top tier of dynamic handheld microphones, crafted to deliver unmatched vocal clarity, warmth, and detail for lead singers, broadcast presenters, and public speakers.

Featuring a tight supercardioid pick-up pattern, the MD 431 II offers extreme off-axis rejection to prevent acoustic feedback even when performing directly in front of loud stage monitors or PA systems. Available now in our Sennheiser pro audio store catalog, this legendary mic combines refined acoustics with heavy-duty construction built for professional touring and broadcast studios.

Key Features & Pro-Level Advantages

• Supercardioid Polar Pattern: Delivers superior feedback suppression and isolates the singer’s voice from high ambient stage sound and instrument bleed.
• Tailored Vocal Response (40 Hz – 18 kHz): Features a smooth frequency curve with a subtle presence boost in the upper midrange for effortless vocal projection through dense mixes.
• Silent Magnetic Reed ON/OFF Switch: Recessed, noiseless magnetic switch integrated into the handle, featuring an ON-position lock to prevent accidental muting during performances.
• Shock-Mounted Internal Capsule: Advanced internal suspension suspension system reduces grip and handling noise to an absolute minimum during handheld use.
• Integrated Hum-Compensating Coil: Built-in humbucking coil protects signal integrity against electromagnetic interference (EMI) from stage lighting rigs and electrical lines.
• Refined Stainless Steel Basket: Hardened multi-stage pop grille protects the dynamic element while dampening vocal plosives and wind noise.
