Sennheiser MD 421 KOMPAKT Dynamic Microphone

Studio Legend Redesigned: Sennheiser MD 421 KOMPAKT

The Sennheiser MD 421 KOMPAKT brings the legendary full-bodied tone, pristine clarity, and off-axis rejection of the classic MD 421 studio microphone into a streamlined, compact form factor built for modern recording and live sound environments.

By housing the exact same acoustic capsule and stainless-steel basket as its iconic predecessor in a significantly smaller body, the MD 421 KOMPAKT allows sound engineers to position the mic effortlessly in tight spaces—such as crowded drum kits or crammed guitar cabinets. Available now in our Sennheiser pro audio store catalog, this dynamic workhorse offers unmatched durability and precision.

Key Features & Pro-Level Advantages

• Legendary MD 421 Sound Capsule: Delivers full-spectrum frequency reproduction (30 Hz – 17 kHz) with identical warmth, articulation, and punch as the original MD 421.
• Ultra-Compact Form Factor: At under half the weight (159 g) and length of the MD 421-II, it easily fits around tight tom mounts, cymbals, and stage rigs.
• Redesigned Fail-Safe Mounting Clip: Features a newly engineered, ultra-sturdy mounting clip integrated into the microphone frame to ensure wobble-free positioning.
• Internal Bass Tube Technology: Preserves extended low-frequency response down to 30 Hz for powerful kick drum, tom, and bass cab tracking.
• Exceptional Off-Axis Rejection: Tight cardioid polar pattern isolates the target sound source while suppressing spill and bleed from nearby drums or stage monitors.
• Extremely High SPL Handling: Effortlessly captures loud transient peaks from heavy drummers and high-wattage amplifiers without distortion.
