Left Speaker works only temporarily for about 10 minutes or so.
So, I have bought my Kingston HyperX Cloud II headset in 2015. They have been working well until recently, when my laptop won’t discover the HyperX soundcard (the Dongle). I’ve discovered that the dongle was faulty and luckily for me they sell it separately from the headset on the official HyperX website. After acquiring the dongle, the computer was able to identify my headset and it worked fine for a week or so, when my left side of the headset just died. No sound would come through.
