4. Maintenance

4.1 Cleaning

To maintain optimal performance and hygiene:

  • Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
  • Gently remove any earwax or debris from the ear tips and speaker mesh using a small, soft brush or cotton swab.
  • Avoid using abrasive materials, solvents, or harsh chemicals.

4.2 Water Resistance

The Buds Pro 2 are rated IP55 Water Resistant, meaning they are protected against dust ingress and low-pressure water jets from any direction. While they can withstand sweat and light rain, they are not designed for submersion in water. Ensure earbuds are dry before placing them back in the charging case.

4.3 Storage

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

5. Troubleshooting

If you encounter issues with your Buds Pro 2, try the following solutions:

ProblemPossible Solution
Earbuds not pairing
  • Ensure earbuds are charged.
  • Turn Bluetooth off and on again on your device.
  • Forget "Buds Pro 2" in your device's Bluetooth settings and re-pair.

No sound or low volume
  • Check device volume and earbud volume (via Smart Dial or app).
