Is there a way to get a new 2.4ghz pc dongle for a Barracuda X Chroma?

Hello, to make things very simple I accidentally washed my 2.4 dongle and I need to replace it. I don’t know where to go to do so. I use the headset for streaming and using it in bluetooth mode on the PC doesn’t offer the right amount of audio channels and compresses the audio I’m getting terribly. 2.4 is my only option. Headset is also frequently turning the mic volume to zero of it’s own accord but that is a separate issue.
