Rugged build for professional applications

Sennheiser knows a thing or two about capturing sounds — they've been building professional-grade microphones for over 65 years. Their MD 421 II dynamic microphone carries on the legacy of the original MD 421, for decades one of their most popular microphones. This classic microphone features a large diaphragm that'll handle high sound pressure levels, so go ahead and stick it on the toms or in front of the Marshall cabinet — it'll take it, no problem.

Versatile, too

The MD 421 II boasts a cardioid polar pattern for excellent directionality and feedback reduction. The five-position bass roll-off switch makes this supremely versatile microphone at home with many other applications, like broadcast announcers or vocal groups.

    Why a dynamic mic?

    Dynamic microphones are engineered for the rigors of live performance and life on the road. Thanks to a very simple and rugged design concept that relies on few internal parts and no electronic components, they're tough, durable, and require no outboard power source to operate. Looking to outfit your church's PA system with vocal microphones? Need to mike your lead guitarist's cabinet for a big club gig? You'll find dynamic mics to fit the bill. If, however, you're looking for a recording microphone to capture sounds in exquisite detail, consider a condenser mic instead.
