In “titantv” TV grid listings, what does the symbol mean withe the headphones and the letter S in the middle?
When I click on a program, there are often black boxes/squares (with white letters or symbols in the middle) after the show description, one says PG which I assume is its rating, like Parental guidance, one says HD, which means id assume “HD programming” and the one with “CC” I’d assume is Closed cationing….
***But what is the symbol with the headphones and the letter S?……Stereo?!?!?! I have no idea, and cant find the symbols in the help section. Showing a link with these symbols would be a bonus 
It’s available in stereo
