The TRITTON AX Visor Bluetooth hands-free kit incorporates state-of-the-art wireless technology.
The AX Visor functions as a portable speakerphone when linked to a Bluetooth cell phone supporting headset or hands-free profiles. The AX Visor will also automatically detect between hands-free car mode and speakerphone mode. In car mode the unit will activate the unidirectional microphone, while in speakerphone mode the omnidirectional microphone is activated. An integrated accelerometer will detect vibration in a vehicle and automatically connect to the paired phone. Underneath the sleek, black bezel is an OLED screen that provides information to the user, including caller ID.
