Shure Microflex MX400SE Series microphones are miniature gooseneck-mounted electret condenser microphones designed for speech and vocal pickup. Their high sensitivity and broad frequency range make them suitable for recording, as well as sound reinforcement applications.

MX400SE microphones can be screwed onto a mic stand or the supplied 5/8 inch 27-threaded flange. They can be easily changed from side-exit to bottom-exit to conceal the cable. All models include an in-line preamplifier and a 3 m (10 ft) cable. Each microphone is available with interchangeable cardioid, supercardioid, or omnidirectional cartridges.
