Dynamic multi-purpose microphone
Our take on the Sennheiser MD421-IIby Crutchfield's Ken Nail
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.
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.

Overview: The Sennheiser MD 421-II is a dynamic cardioid microphone that is designed for handling high sound pressure levels, particularly guitars and drums. It is also an excellent choice for group vocals and radio broadcasting. The MD 421-II has a rugged metal construction for long-term reliability. The MD 421-II is manufactured in Germany, and comes with a swivel mic stand mount (with a 5/8"-to-3/8" thread adapter), and a hard plastic storage case.
