Ok, so here is what I'm trying to do:

 

Recently, I've added a second USB headset to my Flight Sim. I am using two Logitech G330's. But, the first headset is the one I use to talk and listen to ATC. The second is for people who come to fly with me side by side so that they can hear what I am hearing. I am using a splitter to split the headphone line on my headset into two feeds, one plugs into the first headset, one feed into the second headset. That works great.

 

So both of my headsets have a mic and headphone cord that plug into a box that is a USB to the computer. So, I focused on the second headset. I have Windows set up to send what I say in the mic to VOX ATC and the other headset so that the other person hears my voice and what ATC says back. But, I want to get it to where the second headset's mic is wired into my headphone feed on my headset.

 

Since I am using a splitter to provide headphone audio to the other headset, that means that I am not using the USB connection for the other headset. The problem I have come into contact with is that the headset doesn't have batteries meaning that the USB powers the headset! I noticed though that headphone connection works without USB power. But the mic doesn't work unless the USB is plugged in powering it. My goal is to avoid using another USB connection.

 

Here are my Questions:

 

1. Is there such thing as a battery powered headset with a mic that still has a headphone and mic cord attached to avoid using another USB port.

2. Are splitters reversible or can they split sound into two feeds, and also combine two feeds into one?

3. Would it be more efficient to use the USB connection for the other headset instead of trying to split it? If I do this, is there a way to route the second headset's mic feed into my headset with Windows?

Ok, I've made a decision. I am going to buy another headset just like mine now. The reason is because it has to be powered via USB, so I have to use USB connection for both headsets. Is there a way to use mix two audio feeds into one?Should I use splitters or an audio switcher?
