Maintenance

Cleaning

Regularly clean the earbuds and charging case to maintain optimal performance and hygiene. Use a soft, dry cloth to wipe surfaces. For the eartips, remove them and clean with a mild soap solution, then rinse and dry thoroughly before reattaching.

Water Resistance

The IPX8 rating means the earbuds can withstand submersion in water up to 1 meter for 30 minutes. However, it is recommended to dry the earbuds completely before placing them back in the charging case to prevent damage to the charging contacts.

Troubleshooting

  • Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid. Check your device's Bluetooth settings to ensure "TOZO T12" is selected. If issues persist, try resetting the earbuds (refer to the quick start guide for specific reset instructions).
  • One earbud not working: Place both earbuds back in the charging case, close the lid, and then open it again. This often re-syncs them.
  • Charging issues: Ensure the USB-C cable is securely connected or the wireless charging pad is properly aligned. Clean the charging contacts on both the earbuds and the case.
  • Poor sound quality: Ensure the eartips provide a good seal in your ear canal. Try different sized eartips for a better fit. Clean any debris from the earbud speakers.
