The Electro-Voice 647 is a vintage, ultra-compact dynamic lavalier microphone manufactured in Buchanan, Michigan, starting in the 1950s and 1960s. Designed originally as a small hands-free microphone for chest/lavalier wear, public address, broadcast, and pulpit use, it is prized today as an effect mic, lo-fi vocal mic, or harmonic/harmonica mic due to its distinct vintage dynamic character and indestructible build quality.
