Google’s anticipated successor to Pixel Buds has now set off a wave of enthusiasm on the Internet, including some recent appearances in the FCC filing. We have not yet understood exactly what might make these next-generation buds unique, but new acquisitions may give us some hints. Google has acquired Dysonics, a startup specializing in 3D audio.

According to a new report in the agreement, the acquisition including Dysonics̵

7; IP and patents was completed in December. Since then, LinkedIn has confirmed that some of its former staff are developing new hardware on Google itself, which may include 3D audio technology. Following Apple’s AirPods Pro, a pair of next-generation Pixel Buds may eventually receive spatial audio support.

If you have not heard of Dysonics before, then you are not alone. The company was founded in 2011 as part of the UC Davis technology incubator; to date, its biggest project comes from a partnership with Virgin America to provide surround sound for its aircraft’s in-flight entertainment system. Although there is no guarantee that Dysonics’ audio technology will be particularly suitable for Pixel Buds, it seems to be able to compete with Apple’s best-selling wireless headphones.
