i21Earbuds: Bluetooth 5.3 earbuds for active use

These true wireless earbuds use Bluetooth 5.3 for a stable connection during workouts, runs or daily commutes. The IP7 waterproof rating protects the earbuds from heavy sweat and rain. Soft, flexible ear hooks and three sizes of silicone tips keep the 3 g buds secure during movement. They suit anyone who wants cable-free audio that stays in place.

Upgrade from older Bluetooth earbuds

Moving from an earlier Bluetooth version gives you three times faster transfer speed and fewer drop-outs during calls or games. The 14.2 mm drivers with a triple-layer composite diaphragm boost bass by 43 % while reducing distortion. If your current buds lack secure hooks, distort at volume or lose signal outdoors, this model addresses those gaps.

48-hour total playtime with LED case

Each charge delivers 8 hours of continuous listening; the charging case extends that to 48 hours. A USB-C cable is included for recharging the case. The built-in LED display shows remaining case power at a glance. Heavy all-day sessions will need a top-up, and the case adds bulk compared with ultra-compact rivals.
