Hey! Do you know what would be really, like, super useful? If you could pop your fitness tracker out of its strap and use it as a Bluetooth headset to take a call, said no one ever. Welcome, then, to the weird world of the Huawei TalkBand B2, a wearable that's also a Bluetooth headset. It arrives with an air expectation unparalleled outside of a sequel to Battlefield Earth. What I'm saying is, the original TalkBand B1 was possibly the worst wearable ever. So expectations are not stellar. Battery and screen Pop it out of the mostly pleasing packaging and the TalkBand comes 90% charged.
