Sony ECM77 with locking minijack for UWP transmitter

The ECM-77 is frequently seen and heard 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-77BMP which is supplied with a 3.5mm locking jack for use with WRT-805 and UWP series wireless transmitter.

Much better quality than the standard microphone supplied with the D11 system.
