Xbox series x party chat with xbox one players?

Everywhere (including all games even series x games show the new gamertag but in parties/chat, on the homescreen, in the xbox app, and in the system menus show the old one.

Yes,

Anyone one can be on any of the...

Xbox One,

Xbox One S,

Xbox One X,

Xbox Series S,

Xbox Series X,

and join party's and play the same game together, no matter who is playing on any of these consoles.

From what I understand the series X is pretty much a much more upgraded Xbox One & I believe Phil Spencer has stated that people with Xbox One or Xbone X or S will still be able to chat in parties with those who have a series X so people who can't upgrade
don't need to worry about it right away (Except for the new games & upgrades)

I could be mistaken however.

Xbox One and Xbox 360 party systems are not compatible with each other. You can only join other Xbox One players in party chat.

You can chat with Xbox 360 friends using Skype though.

Hashbrown, I have the same setup with my xbox series X, do you have any issues with party chat and game volumes or echoing in the party chat? Do you have any idea if I can alter audio settings for the mic through my computer?
