Hi! Thanks for taking interest in my problem.
I went through the product page, and have multiple times before. My problem didnt seem to have generic solution to it, so I contacted their support team via email. Their reply which suggested I try a factory reset, did not work. They did also include a fallback in the email reply, saying I should send the product away to one of their resellers or associate resellers for "further investigation". The solution is plausible, but I really dont think the headphones themsleves are faulty, and hence sending them away would probably only cause me inconvinience in time, and probably money.
The headphones do however work properly on mobile devices (iPad, and a Samsung Phone), so I think this is rather a fault on WIndows, as is explained in a reddit post that an answer below linked to. The post concludes pessimistically, but I hope WIndows can do something on their part to solve this, as I'm not the only one facing this issue.
Thanks again!
