The SHURE's MX185 cardioid lavalier condenser microphone is intended for speech applications such as broadcasting, speeches, and lectures, as well as use in places of worship. Interchangeable cartridges (available separately) are used in all Microflex series microphones, allowing you to switch between cardioid, supercardioid, and omnidirectional condenser cartridges simply by screwing them on to the top of the lavalier mic. The MX185 comes with an in-line preamplifier and a 1.2m cable with a TA4F connector for wired usage.
