Get to know them!

One of Sennheiser’s most popular microphones! It’s the MD 421-II’s versatility that has made this mic so widely acclaimed. Its ability to handle high pressure levels makes it a natural for guitars and drums, but that’s just the beginning. The MD 421-II’s full-bodied cardioid pattern and five-position bass control mean it’s an excellent choice for most instruments, as well as group vocals or radio broadcast announcers. One listen and you’ll know why it’s a classic.

A cardioid mic for a host of applications!

The MD 421-II is one of the best-known microphones in the world. At Sweetwater, we’ve found that its excellent sound qualities enable it to cope with the most diverse recording conditions and broadcasting applications.

Feedback rejection and bass roll-off

The MD 421-II’s cardioid pattern offers outstanding feedback rejection, making it an excellent choice for live situations or recording environments where bleed from other instruments may be an issue. And the five selectable bass roll-off settings control proximity effect, so you can use the MD 421-II in close-miking situations and still get clean, clear response with no unnatural bass boost.

A sturdy, reliable mic

The MD 421-II has a glass composite housing and hardened stainless steel basket for rugged and durable performance in the studio or onstage. The sound inlet basket is refined steel for capsule protection. When you consider the lifetime performance and versatility of this mic, it’s easy to understand why the MD 421-II is world renowned for quality and value!

Sennheiser MD 421-II Features:

  • Glass composite housing and hardened stainless steel basket — rugged and durable
  • Five-position bass roll-off switch — compensates for proximity effect
  • Frequency response 30Hz–17kHz
  • Effective feedback rejection
  • Clear sound reproduction
  • Acoustic components enclosed in inner chassis — reduced sensitivity to dust and humidity
  • Internal bass tubes help deliver accurate low-end response
  • Handles exceptionally high sound pressure levels
  • Mic clip included
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
