Hi Lovinlakelyfe,

We're so sorry to hear that you are having charging and pairing issues with your WF-1000XM4 earbud headphones. This is definitely not the customer experience we want you to have. Your feedback is extremely important to us and is very much appreciated.

Make sure to clean the charging ports on the earbuds and charging case. Then check the indicator on the charging case. If you haven't yet, check this article to make sure you are charging the earbuds properly:

The headphones do not charge (WF-1000XM4) - https://www.sony.com/electronics/support/wireless-headphones-bluetooth-headphones/wf-1000xm4/articles/00265210

When you pair the headphones using the Bluetooth settings of the connecting device, select the headphones model name without the LE- prefix. If you only see the headphones model name with LE- prefix, wait for a few seconds until the model name without prefix LE- is displayed.

If the headphones won't pair with the device or won't connect with the device once paired (WF-1000XM4), follow the steps from this link to troubleshoot Bluetooth pairing issues when using the WF-1000XM4 earbud headphones: https://www.sony.com/electronics/support/wireless-headphones-bluetooth-headphones/wf-1000xm4/articles/00264979
