Why is the button on the charging case of the Xiaomi OpenWear Stereo Pro unresponsive?

If the button on the charging case of the Xiaomi OpenWear Stereo Pro is unresponsive, please refer to the following information:
1. Ensure the charging case has sufficient charge. A low battery can prevent the button from functioning properly. Charge the case fully and try again.
2. Dust, lint, or other debris can block the button mechanism. Inspect the button area and gently clean with a soft, dry cloth or a small brush.
3. Frequent use, pressure, or accidental drops can wear out the button or affect its internal mechanism, causing it to become unresponsive.
4. Extremely cold or hot environments can temporarily affect button responsiveness. Allow the charging case to return to normal room temperature before testing again.
5. If the button still does not work after checking the above, it may be a hardware fault. Please contact the after-sales service for inspection or repair.
