Maintenance

Cleaning:

• Regularly clean the earbuds, ear tips, and charging contacts with a soft, dry, lint-free cloth.
• Remove ear tips and clean them with mild soap and water if necessary, ensuring they are completely dry before reattaching.
• Avoid using abrasive materials, solvents, or aerosol sprays.

Storage:

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

Water Resistance (IPX7):

The Rulefiss BX27 earbuds are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for workouts and running, protecting against sweat and splashes.

• Do not intentionally submerge the charging case, as it is not waterproof.
• Ensure earbuds are dry before placing them back into the charging case to prevent damage to the charging contacts.
• Avoid using the earbuds in saunas, steam rooms, or for swimming.

• Forget "BX27" from your device's Bluetooth list and attempt to pair again.
• Try pairing with a different device to rule out device-specific issues.

No sound or low volume:

• Check the volume levels on both your device and the earbuds (using touch controls).
• Ensure earbuds are properly seated in your ears and that the ear tips form a good seal.

Charging issues:

• Ensure the USB-C cable is securely connected to both the charging case and the power source.
• Verify that the power source is functional.
