When Sennheiser unveiled the first earbuds to use its Ambeo 3D audio technology, it limited them to iOS users. Are they ever going to come to Android? Yes, apparently -- with some help. Sennheiser has revealed that it's partnering with Samsung to bring Smart Surround's binaural, recording-based sound to Android devices. The company's Andreas Sennheiser says the collaboration is necessary for "credibility." South Korea is "one of the most technology-savvy countries," he says, and makes an ideal testing ground for new hardware. We'd add that Samsung is also the dominant Android phone maker, so any support from its side virtually guarantees a solid foothold in the market.
