The only explanation to this problem is 2 sided.
One side is. The dongle or the Y Splitter used is being faulty. Which is up to the product holder to replace if its the dongle. The Y splitter costs around $ 3-5 at most. The dongle isnt replaceable since you would need a new cable.
The second side is that the headset is so low grade inside when put together that it falls apart from a little shaking.
My own Hyperx Cloud II has a problem with no Bass coming out of the left but LOTS in the right. Checked everything “FYI i work as a Data Technician.” Balance is as it should be. Headset has never been dropped on the floor or hit to make enought impact on it to wiggle wires around. Basicly i noticed when i wiggled the wire and the Jack 3.5 in the dongle moved that sound would get worse. Im an active user of Discord, and i got LOTS of problems with this headset there. For once Everytime you connect something to another device in this example 3 spots in total. You lose around 2 Db. “Decibel” Which is the meassurement of the active line between what it can broadcast.
So im losing a total of 6 Decibel. PC-USB. Dongle - JACK. Microphone - Headset. Sooo many places that the problem could be at.
I know for sure that im going to look for another headset. Im not happy about the way that Kingston decided to make this one. I thought it would be more durable than others for the price they want for it. Granted this is written in 2019. The headset is barely 2 months old.
