ROKU WIRELESS SPEAKERS FOR NON-STREAMING PROGRAMS

I am considering buying ROKU Wireless Speakers for my TCL Roku TV.

Will these speakers work on non-streaming TV programs, e.g. an NFL game on NBC, as well as a streaming program? In other words, do the speakers function regardless of the source of the program? 

The reason for my question is because my Bose Wireless ear buds only function on streaming programs. I want wireless speakers that work on all programs. THANKS!
