Comment on i have a problem with USB c charging đ

Have you checked what voltages arrives on the board if you use a regular USB-C charger? Maybe the headphones negotiate and need a higher voltage than 5V. Does it charge with only 5V supplied? (could be forced by using an A-to-C cable in case of Power Delivery)

Yeah i have cheked and It only used 5v what did you mean by forcing AtoC cable ?

For Power Delivery, higher voltages are negotiated using the CC (configuration channel) pins. If you use an A-to-C cable, the A side does not have the CC pins and therefore you canât get more than 5V.

Are you sure ? How does a standard phone fast charge then , its not the case anyway cause the headphones regularly charge at 5v so itâs enough⊠Thanks anyway for your comment đđ»

There are other fast charging standards than Power Delivery. USB Battery Charging defines that when the data lines are shorted, a device can draw more current (up to 1.5A), but still at 5V. QuickCharge on the other hand uses the data lines to negotiate higher voltages, so an A-to-C cable canât protect you from that.
