Huawei's TalkBand B1 is a smart wearable device that includes a removable earpiece (which is why it is called a TalkBand). It supports several fitness applications (steps recording, calories burned, sleeping pattern monitor, etc.). The display is a 1.4" 128x16 white flexible (curved) PMOLED made by Futaba.
The Talkband is now shipping in China, Europe and in the UK (£99).
