| Hi @elcheesii2 | |
| Some components on the USB daughter board or the motherboard would have been damaged by the excess voltage and would need to be replaced. Hopefully it may only be a fuse | |
| There is no information online regarding the schematics for the headphone boards so the best that you could initially do is to open up the headphones to gain access to the boards (use link in above answer) to check what the damage is i.e. burnt out or blown components etc. | |
| This is where it becomes difficult because if a component is burnt out and you can no longer make out what the markings were on the component itself it would be difficult to know what value component to replace it with. | |
| Here’s an image that shows one particular component that ''may'' be a fuse but maybe not. I cannot make out what the designation for the component is on the board where it is located but if it has an F designation, it is a fuse. Use an Ohmmeter to check if it is OK i.e. it should measure 0.00 Ohms - a short circuit. | |

| + | Here’s an image to show how to set up the meter and where to test. |

| + | |
| + | Place the meter leads between the two green arrow points and check that there is a 0.00 reading on the meter. |
| + | |
| + | If so then place the meter leads between the two red arrow points and check. If the meter shows OL or nothing at all, then check between the red arrow on the USB connector and the yellow arrow on what may be the fuse to make sure that it measures 0.00. |
| + | |
| + | I may have it wrong if the USB connector is upside down as to what is shown in the image so then check between the green arrow and the USB connector and the yellow arrow. |
| + | |
| + | If that test OK then place the meter leads between the yellow arrow and the orange arrow to measure directly across the fuse itself. It should measure 0.00 Ohms if it is a fuse that is. |
| + | |
| + | If it is a fuse it is easier to get a replacement fuse and unsolder the old and resolder the new than to try and find a replacement board, as you would need to know the “board number” and search for it, given that there aren’t any spares available for the headset or none that I can find anyway. You may have better luck |
