A survey of OTT subscribers revealed that viewers often use a portable tablet or the TV’s built-in speaker to watch content. As more and more content is produced in formats such as Dolby Atmos or MPEG-H audio, it is difficult for viewers without separate surround speakers to experience the immersion that spatial sound provides.

“Sennheiser’s Ambio technology was the perfect format for ‘Stranger Things’,” said Mark Paterson, a mixing expert in charge of re-recording ‘Stranger Things Season 4’. “Vekna’s villainous horror voice overwhelms the atmosphere of the drama. I’m very impressed that Sennheiser has achieved such tension in a stereo system.
