Some fitness bands are capable of displaying phone calls and notifications on your wrist, but Huaweis new wearable device wants to make your hands-free phone calls more convenient. The TalkBand B1 is a fitness wristband that doubles as a Bluetooth headset for taking calls on the go. The device is capable of pairing with your smartphone through NFC and Bluetooth 4.1, although the company says it will only be available for Huawei handsets when it launches.
