Bluetooth Audio Smart Glasses are wireless audio eyewear designed to deliver open-ear listening while supporting hands-free calls. With a built-in microphone, you can handle voice communication directly through the glasses, making it convenient for everyday work and travel scenarios. These smart glasses feature touch control, along with volume control functionality, so you can adjust audio without reaching for a separate device. The on ear headset type helps keep audio experiences aligned with typical eyewear comfort. For power, the Glasses3 model uses a built-in lithium ion battery. The battery capacity is 55 mAh, and charging is powered via USB (5V input). The design is also sweat resistant, supporting more practical, active day-to-day use.
