Shure Microflex MX400 Series microphones are miniature gooseneck-mounted electret condenser microphones designed primarily for speech and vocal pickup. They can be mounted on lecterns, pulpits, or conference tables. All models include a preamplifier and are available with interchangeable cardioid, supercardioid, or omnidirectional cartridges (sold separately). Microflex Gooseneck microphones bring a whole new meaning to the word flexible with their fully adjustable gooseneck.
