I tried sticking a pin in the hole and there was no click. I tried the reset method, still not charging. I've always been using the USB cable it came with and have always been charging it with my MacBook Pro without any problems until now. Tried using a different USB cable, nothing. Tried charging it with a portable power bank, nothing. I can't take them back because it's been more than 30 days. I didn't break them, I take good care of them, there's no reason why multiple people should be having this same issue.
Welcome and thank you for considering SONY Community!
Connect the supplied micro-USB cable to the headset, and then connect the other end to a computer booted.
Make sure that you connect the plug of the micro-USB cable in the direction as shown in the illustration below.
Charging starts when the headset and the computer are connected.
Make sure that the indicator (red) lights up. Charging is completed in about 2.5 hours* and the indicator (red) goes off automatically.
* Time required to charge the empty battery to its full capacity
Use the micro-USB cable supplied. You may not be able to charge the headset with other cables.
This headset cannot be turned on, and the BLUETOOTH function and noise canceling function cannot be used while charging.
If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.
