Maintenance
Cleaning
To maintain optimal sound quality and hygiene, regularly clean your earbuds and charging case.
- Use a soft, dry, lint-free cloth to wipe the earbuds and charging case.
- For ear tips, remove them from the earbuds and gently clean with a mild soap solution if necessary, then rinse thoroughly and allow to dry completely before reattaching.
- Avoid using abrasive materials, solvents, or harsh chemicals.
Water Resistance (IPX7)
The F9 earbuds are rated IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter deep for 30 minutes. This makes them suitable for daily life activities such as sweating during workouts or use in light rain.
- Do not intentionally submerge the charging case, as it is not waterproof.
- Ensure earbuds are completely dry before placing them back into the charging case to prevent damage.
- The IPX7 rating applies to the earbuds only, not the charging case.
