A Swedish company called Earin is developing what they are calling "the world's smallest wireless earbuds." The earbuds boast stereo quality and are connected wirelessly.
"The hardware enabling these tiny new devices is the CSR8670, our leading-edge flash based audio system-on-chip platform," Kevin Carey, CSR senior manager of audio marketing, told Fast Company. "It integrates advanced wireless connectivity with embedded flash memory and many other capabilities that enable manufacturers to design leading-edge wireless headsets and speakers."
The CSR8670 hardware was released back in 2011, but it seems as though developers were waiting for the release of a new ADK (accessory development kit) that comes equipped with an updated "True Wireless Audio" application. This software allowed the manufacturers to design products that don't require wires to connect to the left and right speakers, respectively.
"We designed the application to ensure audio is so tightly synchronized it delivers the same user experience as a wired headset or speaker, and in conjunction with our aptX audio codec delivers CD-quality audio with no wires to be seen," Carey said. "This capability seems to have fired the imagination of a number of companies who are using it in some exciting new products."
The company has raised $1.5 million through their Kickstarter campaign. They are expecting to begin manufacturing in December and will begin shipping in January 2015.
