The Shure WL185 is a cardioid subminiature lavalier microphone with signal characteristics ideal for general sound reinforcement applications. The cardioid pick up pattern provides adequate rejection of off-axis ambient signal that can cause noise and feedback. The low-profile subminiature design is ideal for applications where the microphone must be concealed. The hardwired 4 foot cable terminates to a 4-pin TA4-female connector which is compatible with Shure wireless transmitters and power supplies.
