Introducing the CALCINI Wireless Earbuds, designed with an IPX8 waterproof rating and advanced Bluetooth 5.3 technology, making them the perfect companion for your active lifestyle. Whether you’re hitting the gym, going for a run, or simply enjoying music at home, these earbuds deliver exceptional performance and comfort.

These earbuds feature an ergonomic design, ensuring a secure fit with a choice of four sizes of eartips (XS, S, M, L) tailored for different ear canal sizes. The included earwings (S, M, L) provide additional stability, preventing the earbuds from falling out during vigorous activities. No matter your ear shape, you’ll find the perfect fit for maximum comfort.

One of the standout features of the CALCINI Wireless Earbuds is their IPX8 waterproof rating. This means you can wear them without worry during sweaty workouts or even in the shower. It’s important to note, however, that while they are waterproof, the Bluetooth signal cannot transmit underwater, so these earbuds are not suitable for swimming.

With Bluetooth 5.3 technology, you’ll experience seamless connectivity with a barrier-free distance of up to 30 meters. In open areas, this distance can reach up to 20 meters, while in office or home environments, you can enjoy a reliable connection within 10-15 meters. If there are solid walls between you and your device, the connection distance may vary, but you can trust that these earbuds will provide a strong link to your audio source.

Pairing the earbuds is incredibly easy. Simply take them out of the charging case, and they will automatically turn on and connect to your device. Once paired, the earbuds will flash a blue light, indicating they are ready to use. When you place them back into the charging case, they will turn off automatically, preserving battery life and ensuring they are always ready when you need them.

Battery life is another highlight of the CALCINI Wireless Earbuds. Enjoy up to 8 hours of playtime on a single charge, and with the charging case, you can recharge them up to four times. The charging case features four indicator lights, each representing 25% of the battery life. You’ll always know when it’s time to recharge your case to keep the music going.

In summary, the CALCINI Wireless Earbuds offer:

Experience deep bass, rich stereo sound, and the freedom of wireless listening with the CALCINI Wireless Earbuds. Perfect for sleeping, sports, workouts, running, and gaming, these earbuds are designed to enhance your audio experience wherever life takes you!
