How to enable Night Mode or Speech Enhancement on your Sonos TV speaker
Night Mode
When Night Mode is enabled, Sonos suppresses the louder sounds from your content, so you're able to listen to your Sonos speaker at night without disturbing the people around you.
On the Now Playing screen, simply tap the Moon icon to the left of the Play icon.
Speech Enhancement
Speech Enhancement makes the vocals on your TV content much clearer. This is great for people who are hard of hearing and a great way to stop any subtitle arguments in your home!
On the Now Playing screen, simply tap the speech bubble icon to the right of the Play icon.
Night mode and Speech enhancement are both available on the Sonos Arc, Beam & Amp.
