Wearing sunglasses means protecting your sensitive eyes from the heat of the sun or as a treatment for health reasons or perhaps for other symptoms. As for wearing them to listen to your favorite music or to make a call with someone, this seems strange to some people.
Huawei launched smart sunglasses that can pair with a smartphone, via Bluetooth technology, for phone calls or listening to music via the built-in microphones and speaker, without the need to wear a headset.

The Chinese company explained that the “Reverse Soundfield” feature allows people in close range not to hear the music playing loudly, while Huawei recommends wearing a headset when making phone calls with sensitive content to protect privacy.

The sunglasses are equipped  with a body posture sensor, which warns the user if their body assumes an unhealthy posture.

The battery charge is sufficient to listen to music for 11 hours or to make phone calls for 9 hours. Charging is done using a charging cable that is magnetically attached to the arm of the glasses, and they contain dark lenses equipped with a UV filter.
