How long does the 50-hour battery last in real-world use?

The 50-hour battery is typically the combined capacity of the earbuds and charging case. Individual earbud playback usually lasts 6-8 hours per charge, with the case providing multiple recharges. Actual time depends on volume levels and Bluetooth connection quality.

Are these earbuds compatible with all devices?

Yes, Bluetooth 5.4 earbuds work with any Bluetooth-enabled device including iPhones, Android phones, laptops, and tablets. They may require initial pairing setup, but after that, most devices will auto-connect when powered on.

What does IPX7 waterproof rating mean?

IPX7 means the earbuds can withstand immersion in up to 1 meter of water for 30 minutes. This covers sweat, rain, and splashes during workouts, but they are not designed for swimming or diving.
