  • Compact and Lightweight: The microphone is small and unobtrusive, making it ideal for situations where you want a discreet audio solution.
  • 4-Pin Connector: The ECM-322BC terminates in a Sony 4-pin connector (SMC9-4P), which is compatible with specific Sony wireless bodypack transmitters like the WRT-8B, 822A, or 822B.
