Listen to Dolby Atmos
Apple is finally adding in support for Dolby Atmos this fall with tvOS 12. This will come as a free update this fall and if you have a compatible sound system, you can listen to sound that comes at you from every angle.
Dolby Atmos is like 5.1 surround sound, but on steroids. Instead of just hearing sound behind you, Atmos includes sound above you and really opens up the soundstage.
Look out for Dolby Atmos soundbars and sound systems on sale during Black Friday.
