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