The Plantronics M90 Bluetooth®headset is multi-talented: it delivers enhanced HD audio clarity when used with wideband-enabled smartphones and mobile network. It speaks three languages. During set up, you simply follow the voice prompts to select English, Mandarin, and Cantonese for the audible status alerts on talk time, battery level, connection, and more. You can control music tracks and volume without touching your smartphone. If you forget it in the car or at the office, the M90 knows to enter its DeepSleep hibernation mode to conserve the battery. Using the lightweight and comfortable M90 is so easy and comfortable that you can finally free your cheek from your smartphone.
