In this era when intelligence takes over our lives, there are more and more smart products such as mobile phones, tablet computers, and unmanned cars. In recent years, the concept of Bluetooth audio glasses has also become popular. What are Bluetooth audio glasses? This modern people’s question has given glasses, a long-standing optical technology product, a new life in the intelligent era.

Bluetooth audio glasses

Bluetooth audio glasses, as the name suggests, give the glasses the function of playing audio, so that the glasses not only enhance our visual experience but also bring the enjoyment of listening.

The technological innovation is that the left and right temples of the smart sunglasses are integrated with a miniature speaker and a miniature microphone, and the soundhole is around the temples, close to the ears, and the sound from here can be accurately received. There is no need to amplify the volume because it is very close to the ear and the volume is enough to be heard. This is smart audio glasses. Moreover, this sound is directional, and most of the sound coming out of it will only be transmitted to the ears, and the people next to it can hardly be heard. Even in a quiet office, colleagues one meter away can hardly notice.
