1. Volume setting problem: Please check whether the volume setting of your 360 drops is correct. You can solve the problem by adjusting the volume button or setting the volume on the mobile APP.
2. Equipment failure: There may be a failure of the 360-drop speaker, resulting in no beep. You can try to restart the device or restore it to factory settings. If the problem persists, you may need to contact the manufacturer to repair or replace the speakers.
3. Bluetooth connection problem: If the mobile phone is connected with 360 water drops through Bluetooth, there may be no buzz due to Bluetooth connection problem. Please make sure that the Bluetooth connection between the mobile phone and 360 water drops is normal.
If the above methods can't solve the problem, I suggest you contact the customer service of 360 small drops or the after-sales service of the manufacturer, who will help solve more specific problems.
