The water resistance condition supported by IP68 is no flowing clear water. However, when the liquids enter the narrow gaps around the earpiece, they will block the dust-proof mesh, resulting in issues like speaker noise or reduced volume.
If you encounter such an issue, please refer to the following steps to solve it:
1. If the liquids come into contact with the speaker, immediately wipe off any residue using a clean, dry cloth. Avoid pressing or rubbing too hard to prevent pushing the liquid further into the device;
2. Allow the device to dry completely before use. Placing it in a dry, well-ventilated area or using silica gel packets can help speed up the drying process;
3. If you suspect that the speaker has been damaged or blocked by these substances, please contact the after-sale service center for inspection.
