Why don't I see Enhanced Headphone Mode in Black Ops 6?

Enhanced Headphone Mode was temporarily disabled in the game from Oct 25th - Nov 4th, however we are happy to report that Enhanced Headphone Mode has returned to the game in full force! 

All pre-existing trials before Nov 4th have been extended to the full 30 days, and all purchased licenses are completely valid. 

For more information about why the feature was temporarily disabled, and other FAQ please see this blog.
