The TCL Alto 8i has a passable stereo frequency response. With its Music EQ, it has a punchy, boomy sound, but it also sounds a bit bright. It’s lacking low-bass, so you don’t feel the deep thump and rumble in bass-heavy genres like EDM. That said, its balanced mid-range is suitable for dialogue-centric content like podcasts. It comes with three EQ presets so you can customize its sound: Music, Movie, and TV.
