They have a speaker and microphones built into each arm which allow you to make and receive phone calls. They're IP67 water-resistant and have no button: you just tap to control them. Tapping also calls up your phone's digital assistant.

Huawei says the glasses could go on sale in July this year, but there's no word on price.
