Sony has officially unveiled its SmartBand 2 after accidentally publishing details about the activity tracker earlier this year. As the leak had suggested, the SmartBand 2's biggest upgrade is a heart rate monitor, which will augment the device's ability to track users' fitness. Like the original SmartBand, it also functions as a sort of triage system for notifications, connecting to users' Android and iOS smartphones and vibrating to let them know about incoming calls, texts, and emails.
Unlike the SmartBand Talk with its 1.4-inch e-paper display, the SmartBand 2 has no screen and instead relies on vibrations and LEDs to get its messages across. It also functions as a music remote and has a smart alarm clock feature that monitors users' sleep and wakes them with vibrations at the best point in their sleep cycle. Sony says the device is also waterproof and offers two days of battery life from an hour of charging.
