Hey, I've been getting back into online gaming with a group of friends during lockdown. I'm mostly on XB1, they're a mix of PC and PS. We're all using Discord for voice chat and I'm trying to find a cost effective way or using a single headset for both game audio and Discord via mobile phone.
I've got XB stereo chat headset and don't really want to go buy a new headset if I can avoid it. I tried one of the Bionik chat mixers (link) on sale at EB and it was absolutely useless. Worked fine for a single source but microphone wouldn't even send a signal as soon as I had 3.5mm and BT connected.
As far as I can tell my only options are to grab a new headset ($$$) or to kludge something together with a bunch of adapters:
Mic ------------\

Mob > TRRS Splitter TRRS Combiner > Headset
\ /
LR /
\ /
Stereo Mixer

LR
/
Xbox > TRRS Splitter
\
Mic
Hoping somebody has a simpler/cheaper idea?
I threw together a cheapie passive mixer for a project once for a "2-input-1-output" (2 audio outputs, 1 set of headphones) which was simply a dual-channel potentiometer in-between the 2 outputs feeding into 1 output jack. In the end I don't touch the dial so fixed R would've worked well enough I guess. It's not "ideal" for the equipment or quality but it was good enough for me. The music still sounded like music in my situation.
Your diagram would be what I would build. As for cost effectiveness depends on what parts you have I guess. Pretty sure TRRS splitters or at least LR+Mic splitters are cheaper to get from AliEx or whatever than making your own. Or if you care how the end product looks lol. I've got a basic 3.5mm stereo input toggle switcher in a plastic sauce container on my home desk :P.
