What customers say
Customers overwhelmingly praise this microphone for its exceptional audio fidelity and consistent reliability, cementing its status as a professional standard. Users highlight the clear, natural voice reproduction and broad frequency response, making it excellent for demanding broadcast and film work. Its miniature size is a noted advantage for discreet placement.

Know before you buy
Yes. The ECM-77B features a two-way powering system, allowing you to use a single AA battery if your camera or audio interface does not supply +48V phantom power.
Absolutely. Its ultra-miniature size and omnidirectional polar pattern make it a industry standard for film and TV, where it is frequently concealed under costumes or clothing.
This model terminates in a standard XLR connector, making it directly compatible with professional cameras, mixers, and audio interfaces.
Because it is omnidirectional, it captures sound from all directions, which provides a natural, open sound. While it is excellent for vocal clarity, you should be mindful of ambient noise in uncontrolled environments.
The package includes the microphone with its power supply module, essential mounting clips for securing it to clothing, a windscreen to reduce plosives, and a carry case for protection.
The microphone comes with a 9.8-foot (3-meter) cable, providing plenty of length for most interview or performance setups.
