What is the MX183 best suited to?
The MX183 omnidirectional miniature lavalier condenser microphone is designed for use in speech applications such as broadcast presenting, speeches, lectures and for use in houses of worship.

What is an interchangeable cartridge?
All the Microflex series of microphones use interchangeable cartridges (sold separately) which means you can swap between cardioid, supercardioid and omnidirectional condenser cartridges simply by screwing them on to the top of the lavalier mic.
Want to go wireless?
The MX183 is designed for wired use and includes an in-line preamplifier and a 1.2m cable with TA4F connector. If you wish to go wireless, choose the WL183 which is the same microphone but without the pre-amplifier and connects directly into any Shure wireless bodypack.
FEATURES
- Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum
- Interchangeable cartridges that provide an optimal choice for each application
