Huawei TalkBand B2

The hybrid of a smart bracelet and a wireless headset is an atypical model among other players in the wearable gadgets market.

2 in 1

The engineers of the Chinese company Huawei have made a 2-in-1 device — it can track activity indicators and turns into a Bluetooth headset in one movement. The metal capsule with the hardware is made in the form of a curved cradle, which is detached from the elastic bracelet by pressing special buttons. On the back side, the cradle is equipped with a silicone ear cushion that securely clings to the ear. The sound quality from the built-in speaker is comparable to low-cost wireless headsets.

Activity

The functionality of the bracelet is fully revealed in the role of a fitness tracker. The device has in its arsenal an accelerometer and a gyroscope, with the help of which activity indicators are monitored. The data is displayed on an OLED display with a resolution of 88x128 pixels or transmitted to a connected smartphone with pre-installed Huawei Wear software. The screen can display icons of the date and time, distance traveled, the number of calories burned, the duration of running and sleep, and also acts as a stopwatch. The model does not have a built-in heart rate monitor.

Sleep phases

The bracelet automatically recognizes the start time of sleep, and the associated programme plots its quality. The smart alarm function also has a place to be, but it does not always correctly determine the phases of REM sleep.

A fine line

In standby mode, the gadget's screen shows the date and time, which once again confirms the very thin line between fitness trackers with a screen and smartwatches. Huawei TalkBand B2 went even further and so far has no analogues at all — there are simply no other similar hybrids of a smart bracelet and a wireless headset.
