Multifunction design Smart Bluetooth glasses are sunglasses with integrated Bluetooth connectivity, allowing you to shield your eyes from the sun while staying connected. They support hands calling and audio playback for everyday use during driving, walking, or outdoor activities. Reduced interference with directional sound These smart glasses use directional sound technology to deliver audio to a specific area, helping minimize external interference. The result is clearer listening in busy environments with less ambient distraction. Private listening and sound isolation Whether you are on a call or enjoying music, sound remains private and is not easily heard by people nearby. This design also helps reduce ear fatigue compared with longterm use of traditional headphones. Builtin quality microphone and noise reduction A builtin sensitivity microphone provides clear HD sound, enhanced by CVC6.0 noise reduction. It helps eliminate both internal and external noise during calls and reduces sound interference in enclosed environments, delivering clearer conversations. Use scenarios Driving or commuting: make hands calls and listen to music or spoken audio while keeping your focus on the road. Walking in busy areas: private calls and audio without disturbing others around you. Outdoor activities or casual work in shared spaces: comfortable, sunprotective eyewear with reliable audio performance.
