Maintenance

1. Cleaning

Regular cleaning helps maintain sound quality and hygiene.

• Use a soft, dry, lint-free cloth to wipe the earbuds and charging case.
• For ear tips, remove them and clean with a mild soap solution if necessary, then rinse thoroughly and dry completely before reattaching.
• Avoid using abrasive materials or harsh chemicals.

2. Water Resistance

The earbuds are rated IP7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for sports and protection against sweat and rain. However, the charging case is not waterproof. Ensure earbuds are dry before placing them back into the charging case to prevent damage.

3. Storage

When not in use, store the earbuds in their charging case to protect them and keep them charged. Store the device in a cool, dry place away from extreme temperatures and direct sunlight.
