Know your battery before you even open the case. The YD03 TWS Wireless Earbuds feature an upgraded LED soft-light display on the charging case, showing remaining power at a glance — no more guessing or opening the lid to check. Paired with a breathing-light indicator, it's a small detail that makes daily use noticeably smoother.
Under the hood, the YD03 runs on a stable full-core Bluetooth 5.3 chip, delivering faster, more reliable connections with smoother calls and music playback. A graphene composite diaphragm keeps the earbuds lightweight while improving response speed and audio fidelity — you get clearer, more responsive sound without added bulk. A built-in noise-cancelling microphone keeps calls clear even in noisy environments, and the micro-charging system charges faster while holding a longer charge per session.
In the box: 1x earphone set, 1x USB data cable, 1x instruction manual.
