Netflix has partnered with Sennheiser to bring spatial audio to the streaming service's original programming, including the recently released Stranger Things season 4.

"Spatial audio will roll out across our catalog beginning today, and you can hear it for yourself by typing 'spatial audio' into the search bar and selecting a show or film that supports it in the search results," a Netflix blog post says. The feature uses Sennheiser's Ambeo technology.
