Dual-ear microphone mount allows you to convert your single ear-worn BP892 MicroSet® to a dual-ear-worn unit for maximum stability and comfort. The BP892 fits on either side of the dual-ear microphone mount, allowing the microphone to be worn to either the left or right of your mouth. The headband easily adjusts to fit both children and adults. The AT8464 is compatible with all BP892 and AT892 microset models. The AT8464 is also available in beige (model AT8464-TH).
