Chosen Solution

This is sort of my last resort, as SteelSeries support/the few YouTube videos I have found haven’t solved anything. My current Pro Wireless stopped powering via the power button about a few weeks ago very all of a sudden (no lights turn on, no beep to indicate that it is on, and both batteries read on the transmitter as fully charged). It just stopped one day while it was hanging on my monitor (no real damage was ever done on this headset). Here’s all the information I have gathered:

  1. The only way it functions normally like it did before it stopped powering is when it is plugged directly into my PC via the 8-pin connecter it comes with. It essentially still works, but only when plugged in with the 8-pin connector (excluding usage of the microphone).2) When I plug in the charging cable (the micro-USB to USB cable), the light next to the power button doesn’t turn on, but it starts breathing (lighting up and then lighting back down on repeat). I have no idea if this does anything. I believe it just means its charging, but it hasn’t done me any good so far, as both batteries are recognized by my transmitter as fully charged. My PC also detects the headset under devices with this method, but it is incapable of doing anything with it.3) My updated SteelSeries software recognizes the transmitter, but prompts me to reconnect the headset (which I cannot do because it won’t power on wirelessly, and it can’t connect to the software through the 8-pin connector). I have opened up the inside of the headset. Admittedly I’m no expert on this sort of thing, but compared to what I found online it visually looks as if everything is fine/appropriately soldered. Could it still potentially be faulty hardware, even though the headset works like normal when using the 8-pin connector? Perhaps it’s a firmware issue that is causing a booting issue, and if so, would there be a way to communicate with the headset and update the firmware using the micro-USB cable? Thank you to anyone willing to look into this problem.

Hey, it could be good to measure the battery voltage. If you left them discharged it is possible that the battery dropped below a threshold voltage. What happens than is the BMS(Battery management system) can prevent the battery from charging as it has dropped below what’s considered a safe level. This would align with most of what you have said excluding the fact that the receiver sees those as fully charged , but this could easily be explained as it is possible that since it no longer powers on it could either be reusing the last available data or could be reading the voltage when charging. Either way, the symptoms seem to be very consistent with a dead battery.

Hey, this isn’t an answer to your question, but I have the exact same problem and was wondering if you have found a fix yet?

I’m having the exact same issue. I messaged SteelSeries support but I’m waiting for a response. Best case scenario the batteries need to be replaced (mine are 2 years old with light use). Worst case I need a new headset. Going to leave one battery charging in the base and the other battery charging within the headset via USB. Will test to see if that solves my issues Will keep you guys posted
