Huawei TalkBand B1 allows you to measure our steps, know the calorie consumption, it has measurement of sleep and some function more. But what is difference is Smartband of others is that offers of output for handset, and that can reply to our calls through this. This model becomes a bluetooth headset that we can put in our ear.
