Actually, are Sony's soundbars good?
Sure, but there are plenty of good options. Don't limit yourself to Sony just because the TV is Sony.
As others have pointed out, advice here is based on a very limited set of information. You mention Windows and Mac, as well as 49" TV and desk. Clearly not a computer workstation (49" monitor is clearly overkill). So what is the use case (monitor, general TV viewing, the main home theater), what gear is feeding content to the TV, what kind of outputs and inputs on the TV, etc might help refine the advice.
