King Lucky i21 Open Ear Clip-On Earbuds | Wireless Bluetooth, IPX4, Glasses-Friendly

Open-Ear Freedom for Active Lifestyles

Meet the King Lucky i21 open-ear clip-on earbuds, designed to sit outside the ear and secure with a discreet, lightweight clip. This design helps you stay aware of your surroundings while enjoying music, calls, or podcasts during workouts, commutes, or daily tasks. The fit is engineered to endure movement, so you can focus on your activity without the distraction of in-ear pressure or ear fatigue.

Glasses wearers often prioritize comfort, and the i21 aims to deliver just that. At only about 4.7g, the buds feel almost invisible, reducing strain and discoloration behind the ears while you power through a run or a long study session. The open-ear approach also keeps your ears cooler on hot days or high-intensity workouts.

Long-Lasting Power and Dependable Connectivity

Stay in the zone with up to 6 hours of playback on a single charge. When you need more, the compact charging case extends listening time to as much as 45 hours, with a generous standby time that keeps the buds ready for action. Bluetooth 5.3 brings a more stable connection, lower latency, and efficient energy use, making pairs smoother across devices and environments.

The i21 is built to keep pace with your routine. A nano hydrophobic coating delivers IPX4-rated waterproof protection, so a light rain shower or sweat during a tough workout won’t interrupt your session. If you ever need to reset the connection, a quick earbud reset function helps you re-pair with minimal fuss.
