The ECM-77 is probably the most-often seen lavalier microphone on TV, and it is used widely in both studio production and on location. Its popularity is based on a combination of excellent sound quality, robust construction, and an attractive cosmetic design. This microphone is the ECM-77BPT, which is supplied with pre-solder bare wire ends. As a lavalier microphone, the ECM-77 is an alternative to the traditional hand-held microphone. Being "hands-free," it allows the presenter to concentrate on her/his performance.
