The ZVEX TB-1 Tea Ball Microphone is actually built inside a stainless steel tea ball. It is designed for specialty use and will reject sounds from sources further than an inch away from its grill. On stage, in a loud environment, it can be plugged directly into a guitar amp that’s turned up to a level that would normally cause the mic to squeal. In a studio, when live recording a vocal track, it will reject the amplifiers and drums. The soft tea ball mesh protects your teeth and can be disassembled and washed in soapy water.
