Maintenance and Care

Cleaning

Regularly clean your earbuds and charging case with a soft, dry, lint-free cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the product's finish and internal components.

Water Resistance (IPX6)

The earbuds are IPX6 water-resistant, meaning they can withstand strong jets of water. This makes them suitable for workouts and light rain. However, they are not designed for submersion in water. Do not soak the earbuds or expose them to pressurized water.

When not in use, store the earbuds in their charging case to protect them from dust, damage, and to ensure they remain charged for your next use. Store in a cool, dry place away from extreme temperatures.

Troubleshooting

Earbuds not pairing

1. Ensure both earbuds are sufficiently charged.
2. Place both earbuds back into the charging case, close the lid, wait a few seconds, then open the lid again to reset the pairing mode.
3. On your device, go to Bluetooth settings and "forget" or "delete" "Monster Open Ear AC339" from your list of paired devices.
4. Try pairing again following the "Pairing with a Device" instructions in the Setup section.

Only one earbud working

Low volume or poor sound quality
