This was used for live recording, and the microphone body is wrapped with urethane to prevent vibration. The recording equipment is broken, so I cannot confirm its operation; it is being sold as junk. There is no rust on the battery terminals. - Type: ECM microphone for audio (with stand holder) - Cable length: Approximately 2 meters - Accessories: Two microphone cables Since it is old, please consider this when purchasing. Shipping may be on the weekend or the beginning of the week. Thank you for your understanding. No returns or refunds, please.
