Audio-Technica AT899 Subminiature Omnidirectional Condenser Lavalier Microphone Overview:

Audio-Technica’s omnidirectional AT899 is engineered for intelligible, accurate voice reproduction. Its low-profile design (a mere 5 mm in diameter) assures minimum visibility. The mic may be worn as a lavalier and is easily hidden in clothing or hair. It offers the convenience of battery or phantom power; its switchable low-frequency roll-off reduces popping.
