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-TH is compatible with all BP892 and AT892 microset models. The AT8464-TH is also available in black (model AT8464).
