MX418 Microflex Gooseneck Microphone

The right speech doesn’t just inform. It can excite and even transform those who hear it. So, we designed the MX418 to treat spoken audio with the detail and respect it deserves. Because clarity commands attention.

Key Features:

  • 18-inch gooseneck
  • 12-inch gooseneck available
  • Low-profile design
  • Dual-flex gooseneck provides easy mic adjustment
  • Versions available with mute button, LED indicator, locking flange and shockmount assemblies
  • Can mount on table, lectern, podium or similar surface
  • Interchangeable cartridges ensure great audio in any environment

How it works

The MX418 delivers the responsiveness to everything you want them to hear—and controls what you don’t. It’s great sound and reliable performance, without noise or distractions. Even installation was rethought and reengineered to be simpler and smoother for AV integration. Precise, tailored-for-speech audio for any size room.

Why it's better

In tune with speech

Microflex microphone cartridges are focused specifically to capture human voice, so the talker always comes through clearly.

No installation headaches

The variety of mounting and form factor options make the MX418 easy to set up in any space.

Clean signal

Shure Commshield is built into Microflex to reject RF interference from ever-present smart phones, keeping the focus on the performance.

Only the detail you want

A snap-fit windscreen keeps breath and plosives from being a distraction. While vibration noise gets absorbed by the integrated shock mount. Only speech gets through.
