A full charge takes approximately 1 hour and provides up to 30 hours of playtime. A quick 10-minute charge can provide up to 10 hours of audio playback.

Maintenance
Cleaning
Regularly clean your headphones to ensure optimal performance and hygiene. Use a soft, dry cloth to wipe the surfaces. For eartips, remove them and clean with a mild soap solution, then rinse and dry thoroughly before reattaching.
Storage
When not in use, store the headphones in a cool, dry place away from direct sunlight and extreme temperatures. The magnetic earbuds help prevent tangling and keep the neckband secure.
Water Resistance (IPX7)
Your Rythflo headphones are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for workouts and use in rainy conditions. However, they are not designed for swimming or prolonged submersion. Ensure the charging port cover is securely closed to maintain water resistance.
