The Plantronics M70 Bluetooth headset is so lightweight & comfortable you may forget you're wearing it. During set up, you simply follow the voice prompts to select one of three language options for the audible status alerts on talk time, battery level, connection, & more. You can also control music tracks & volume without touching your smartphone. If you leave it in the car or at the office, the M70 will enter Deep Sleep hibernation mode to conserve the battery. Using the M70 is so easy that you can finally free your ear from your smartphone.
