The UGREEN HiTune S3 (WS209) in a stylish purple finish are open-ear clip-on TWS earbuds designed for those who want to stay aware of their surroundings while listening to audio. They feature 12mm dynamic drivers with a titanium alloy bio-diaphragm to deliver clear sound, supported by Bluetooth 5.4 for a stable wireless connection using AAC and SBC codecs. Each earbud weighs only 5.3 g and is constructed from a mix of PVC and metal, ensuring a lightweight feel that remains comfortable during extended wear. An IPX5 water resistance rating protects the internals from sweat and rain, making them a practical choice for outdoor activities or workouts. For communication, the integrated AI ENC technology helps reduce environmental noise so your voice remains clear during calls. Battery life is managed efficiently, offering up to 24 hours of playback, with some configurations extending the total time to 30 hours when using the charging case. If you are in a hurry, a quick 15-minute charge provides enough power for 2 hours of listening.
