Sennheiser MD 421 Kompakt Dynamic Microphone
The MD 421 Kompakt takes the sound that has made the MD 421 a fixture on drum kits, guitar cabs, brass, and broadcast desks for decades and puts it in a shorter body built for musicians and engineers who need that tone without the full-length classic's reach and weight on a crowded stand. It carries the same cardioid dynamic voicing that made the original a go-to for tom mics, kick drums, and amp cabinets - present midrange, controlled low end, and enough off-axis rejection to work cleanly in a tight multi-mic setup.
The Kompakt earned a NAMM TEC Award for its design, recognition of how well Sennheiser preserved the original's character while shrinking the footprint. A 30 Hz to 17,000 Hz frequency response keeps it focused on instrument and broadcast use rather than full-range vocal or acoustic capture, and its rugged build is made for the wear of touring and daily studio use. It connects through a standard 3-pin XLR and needs no phantom power, dropping straight into any drum or amp mic setup that already trusts the MD 421 name.
