Netflix Premium memberships now include two additional device downloads plus support for Spatial Audio.

Netflix's Premium subscription plan is getting some upgrades via Spatial Audio support and an increase in the number of devices allowed to perform downloads. Both changes apply to current Premium members, those upgrading to Premium from another plan, or anyone joining Premium for the first time.

At its core, Spatial Audio functions as a kind of simulated surround sound without the need for a home theater setup. And it works with a variety of devices that can stream Netflix, from your TV to your smartphone.

It's currently offered on more than 700 of the service's most-watched movies and TV shows, though Netflix has previously said that Spatial Audio isn't an option for everything . The best way to find out what it is is to search for "spatial audio" in the app or on the website and then pick what you want from the results.
