Get robust audio performance out of a lavalier mic with a subminiature design and a custom cardioid element.

The Shure UniPlex UL4 is a professional MEMS lavalier microphone that is ideal for speech and performance applications in broadcast, corporate and conference environments. The subminiature design and custom cardioid element provide robust audio performance. Each microphone is supplied with a storage pouch, single tie clip and snap fit windscreen. The advanced 1.6 mm Shure Plex cable, first introduced with the award-winning TwinPlex subminiature microphone, lasts longer than competing cables due to a dual redundant ground which doubles as a secondary shield. It also offers virtually zero “memory effect,” won’t kink and is fully paintable.
