I'm not quite sure I understand what you are wanting to do. Are you trying to hear PC audio and Xbox One audio on the same headset?

So I have headset connected to my PC. I was wondering if it was possible to use that same headset to hear Xbox audio through the keymander somehow - (Just like using the mouse and keyboard for both). I do not need to hear both at once, but if that's achievable that would be great!

Ok, I got it now. There isn't a way to hear simultaneous audio from both sources that I'm aware. I suppose you could buy and audio switch and connect the Xbox One controller audio to one input and the PC audio to another input and then connect the output to your headset. I believe Logitech has a dual input headset designed so you can play games and also connect your phone, but I don't remember the model number. This would probably work for your scenario.

Not sure if you figured this one out yet, but I know a work around that will solve your issue. So, to readdress this question and for the good of others...

Your goal is to continue to keep your headphones plugged into your computer, but when you want to hear you Xbox you wont need to unplug your headphones and hook into XBOX controller or whatever..

Solution: In order to do this (which it is possible... I'm doing it now), you will need the following:

1.) a Computer monitor that has a built in headphone 3.5 jack on the back or underneath the I/O panel. This is where you typically plug your HDMI or Display cables into it.
2.) a Male to Male 3.5 end cable (buy on Amazon)
3.) Plug in Male to Male 3.5mm cable into your computer's "Mic IN" port on the I/O panel of the motherboard.
4.) After doing step 3, in the search bar (near start button) of windows open your audio control panel by typing in "Manage Audio Devices".
5.) Click on the "Recording" tab
6.) find the device labeled "Microphone - Realtek(R) Audio and click on it.
7.) After you highlight this device click on "Properties"
8.) Once in the properties click on the "Listen" tab then SELECT/CHECK THE BOX - "Listen to this Device

Summary - Sound coming from your console plugged into your monitor via HDMI, then it gets passed through the Monitor's Headphone jack via that 3.5mm cable into your computer's MIC IN jack. The computer then thinks its a microphone receiving input (sound) from it. You then "pass-through" the sound via "Listen to this Device".

Hopefully this helps. Post is year late, but I'm sure there's someone like me who is in the same boat.

NOTE: Get a quality 3.5mm Male to Male cable. If you cheap out on this, you'll probably receive alot of feedback and poor sound quality. I'm experiencing that right now. So, off to Amazon to get a higher quality cable!

Wow, great idea Chase! I will have to give this a test but it sounds like a great simple solution.

Happy to help Derek. Its working very well for me. In reference to some of the static issues that I was having, it was caused by using a poor quality cable. I ordered a higher quality cable from amazon. This fixed the issue completely.
