The UGREEN HiTune S3 (WS209) is an open-ear clip-on wireless earbud built for people who want music without shutting out the world around them. Instead of sealing your ear canal, the C-shape titanium clip rests on the edge of your ear - so you still hear traffic, a colleague calling your name, or the rickshaw behind you. At just 5.3g per earbud, it stays comfortable through long commutes and long workdays.

Sound comes from precision-tuned 12mm dynamic drivers with composite polymer diaphragms, delivering deep bass and clear mids despite the open design, while bidirectional sound transmission cuts sound leakage by up to 98% to keep your listening private. Bluetooth 5.4 with multipoint pairing, AI noise-cancelling calls, IPX5 water resistance and up to 30 hours of total playtime round out a package built for everyday use in Bangladesh.
