CoollDave@CoollDave thanks again for linking the Twitch stream, literally went straight from posting the review to trying to get the stream started and talking.
I don't know what you consider drastic, but the viewers said it sounded more shrill, tinny, and compressed, which is pretty much the audio difference I heard the game sound change. I WOULD consider the difference drastic, the DS4's smartphone-style TRRS jack provides pretty minimal "it works" quality that gets irritating after a few minutes, and the battery drains faster. That's what leads me to believe the USB dongle that comes with the PC373D is the culprit for reviews calling the mic on that "nasally."
EvshrugNo problem! :)
I agree that the PC373D's USB dongle was causing the "nasally" sound, so I'm happy Massdrop got rid of it completely.
I'm guessing that my 37X's mic and drivers would still sound good if I plug them directly into my motherboard since it has a better DAC (Asus SupremeFX) than whatever the DS4 uses.
