As I've explained before, upgrading to a soundbar is one of the best ways to ensure you can actually understand the dialogue in TV shows and movies. If you have yet to upgrade from your TV's tinny built-in speakers, the LG S80QY soundbar and subwoofer is currently on sale for $376.99 (originally $899.99) after a 58% discount. This is the lowest price I've seen for this item, after checking price-tracking tools.
The LG Soundbar S80QY is a 3.1.3 mid-range setup (meaning three speakers in the soundbar, one subwoofer, and three up-facing drivers on the soundbar). It was released in 2022 with room calibration feature that optimizes the sound based on the acoustics of your home. If you have an LG TV, you can connect to the speakers with "WOWCAST" technology over wifi. The speakers support Dolby Atmos and can playback surround sound formats like Dolby Digital and DTS. It also has a Clear Voice feature to enhance dialogue. If you use Alexa, Google Home, or Apple Airplay 2, you can pair the soundbar with them to control the soundbar with your voice.
