Our Verdict

LG S80QY

LG S75Q

The LG S80QY is better than the LG S75Q for most uses. The S80QY comes with more sound enhancement features like room correction and more wireless playback options. It can also reproduce a more extended low bass, so you feel more thump and rumble in your audio. The S75Q also supports Dolby Atmos content and is a more affordable alternative.
