Jabra today updated its signature Bluetooth headset. The Stone2 keeps its signature twist shape and namesake charger but adds voice control and guidance. On a basic level, the earpiece will read out caller ID or the phone number and either take or end the call by speaking "answer" or "ignore." Many devices can also start a call through speaking the name or number, and Jabra's app platform opens the option of voice-guided e-mail, searches, social networking and text messages.
