(USB &/or 3.5mm to 2.5mm adapters

[Dire_54]

Hello!

I've tried searching for the correct adapters but having some trouble locating a suitable adapter.
Hoping that someone on here can share some insight into this.
We have two headsets (g430 and Kracken Chroma 7.1) that we would like to adjust for use on our phones.
Problem being the Kracken is USB only connection, would need a female USB to 2.5mm male adapter.
The G430 has a 3.5mm stereo and 3.5mm microphone cable that can be plugged into its optional USB adapter. So this headset would require a dual 3.5mm female to 2.5mm male adapter, or the above USB female to 2.5mm male adapter.
Any help would be appreciated!

If faimy sure you can't use a USB headset on a 3.5mm device you'd would need a siganl converter that would need its own power supply as you'd need to convert a analogue into the digital USB signal

Either a combination of two plugs:

or.. try to find single one, I can't find one easily.
DIY attitude and bit of soldering would do the job though out of those two or you could get plain plugs and wiring of your own choice.

Edit: Also the first adapter does not specify that the 3.5mm end is also 4 poles. Not being 4 makes the 2.5mm end being 4 totally useless though so I would assume that it is 4 poles and would work.
