The headphone setup on the Rift S is something they probably saved money on. For me it's not an issue with DCS because I have a simshaker setup on my seat and pedals. I used that setup in Iracing, it's called Simcommander . I wish it worked with DCS. It makes the simulator come alive. I tried the Simshaker addon for DCS but found the effects fake. So what I do is turn off the Rift headphones and send the stock sound from DCS to my shaker setup in my seat and pedals. I works almost as good as Simcommander.
I can feel the burner light, the boards come out and retract, the engines start and shut down ETC. Comms with someone would probably not work because the " shakers" are not designed for speech. I really miss the shaker effect if it's not on. For me its required DCS equipment. I can't get it to work with Rift headphones enabled. But I could use Rift headphones and a "shaker" setup with Iracing through Simcommander.
I'm looking forward to my Reverb G2 and will probably disable the improved speakers on the Reverb
