Many TCL sets deliver incredible brightness, colors, and contrast to meet these needs, but what about sound quality? This isn't usually a feature category that TV brands draw much attention to, and most TV speakers aren't very powerful. But TCL broke away from the norm when it unveiled a partnership with Bang & Olufsen (B&O), a revered audio company based in Denmark. The current TCL TV generation features B&O audio on the QM7L, QM8L, and the monolithic X11L model. Apparently, the built-in audio on some of these TCL sets is so impressive that you may want to skip a soundbar altogether, even if you already own one.
