UGREEN WS209 HiTune S3 Open-Ear True Wireless Bluetooth Earbuds-Black

The UGREEN WS209 HiTune S3 Open-Ear True Wireless Bluetooth Earbuds feature an innovative clip-on design that prioritizes both comfort and situational awareness by resting on the ear’s edge without blocking the canal. This ergonomic C-shape construction is made from durable titanium alloy and TPE, weighing only 5.3g per earbud to ensure a secure, “zero-gravity” fit suitable for high-impact activities like running or cycling. Internally, the earbuds are equipped with 12mm dynamic drivers and bio-diaphragms that deliver immersive 360° panoramic sound, while air conduction technology and a reverse sound wave system help reduce audio leakage by up to 98%. 

For connectivity and performance, the HiTune S3 utilizes Bluetooth 5.4 to provide a stable connection with multipoint pairing, allowing users to switch seamlessly between two devices. The earbuds offer up to 7.5 hours of continuous playback on a single charge, extending to a total of 30 hours with the compact USB-C charging case. A convenient flash-charging feature provides approximately 2 hours of use from just a 15-minute charge. Additionally, these earbuds are IPX5 water-resistant to protect against sweat and light rain, and they feature integrated AI Environmental Noise Cancellation (ENC) with dual microphones to ensure clear voice calls by filtering out background noise. Smart touch controls on each earbud allow for intuitive management of music, calls, and volume without needing to reach for a paired device.
