Shure MX418D/C 18" Desktop Gooseneck Condenser 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. 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.
