DTS, Inc. (Nasdaq: DTSI), a leader in high-definition audio solutions and audio enhancement technologies, today announced that it has expanded its relationship with premium Chinese smartphone brand, vivo, to begin delivering content in DTS- HD® via its digital content service partner, Xunlei. Now, vivo customers can stream content mixed in DTS- HD to their Headphone:X™ equipped smartphones, and enjoy it in full surround sound over headphones. DTS-HD is a high performance discrete audio codec designed specifically to enable streaming services to deliver content to connected devices in immersive surround sound. “It isn't until you experience Headphone:X for the first time that you truly understand the impact of delivering multi-channel audio content to mobile devices,” said Brian Towne, executive vice president and chief operating officer of DTS. “Neuroscience studies have proven that the immersive sound provided by Headphone:X keeps viewers more engaged by providing a more enjoyable and memorable media experience.” DTS Headphone:X expands and focuses sound far beyond the boundaries of a pair of headphones, allowing listeners to hear their favorite content as if it was coming from multiple speakers located around and above them, with a higher degree of accuracy than was ever before possible. “Without sound, there would be no demand for mobile content,” said Mr. Feng Lei, CMO of vivo. “With this in mind, we set out to build a full ecosystem capable of providing our smartphone customers with access to content that provides the ultimate entertainment experience, complete with immersive sound. Through our collaboration with DTS, we were able to create a fully functional content platform capable of providing our smartphone customers access to popular movies and music that they can experience in DTS Headphone:X.” In December of 2013, DTS and vivo announced the launch of the vivo XPlay3S, the first smartphone to ship featuring DTS Headphone:X.
