In contrast, the TCL 65-Inch Class S5 features Dolby Atmos and DTS Virtual:X, which provide immersive 3D sound from its built-in speakers.

Its AI Search and Concierge feature enhances the user experience by learning viewer preferences. Conversely, the TCL 65-Inch Class S5 incorporates the Fire TV experience, which gives users quick access to live TV, video games, and a library of over 1 million movies and TV episodes.
