So far I have been able to test the app with 2 friends on at the same time. The audio quality was on par with PC or Xbox so thankfully no major downgrade. I was using my headphones that contained an inline mic that came with my note 8 to chat with friends, and was told I sound pretty decent during the call. The online mute button on my headphones did not mute me in party chat however you can mute yourself from inside the app manually. It also appears that you must be connected to wifi to get the party chat to actually connect to a room as of right now. Looking forward to see how this handles large rooms of people. Only issue I had was I had 2 instances where it seemed like the app did not recognize me talking. However this only lasted for about a second each time.
