As for the features of the Ear Duo, Sony says it has an unparalleled ambient experience through Dual Listening technology that lets you hear your
music, your notifications, and the surrounding sound at the same time, plus the headset can adjust the volume based on your environment. The built-in Daily Assist feature gives you relevant information depending on the time, location, planned activities, and reads your messages and news, but you can still access the
Google Assistant or Siri if you prefer those. There are also sensors on board that let you shake your head to take or decline calls and skip through your music and the main area appears to be touch-sensitive for swipe and tap controls.
The Xperia Ear Duo is IPX2 splash-proof and battery life is expected to be around 4hrs, but it ships with a case that provides 3 more charges on the go, including a fast-charging ability to get 1h of listening with 7mins of charging. There are also 3 different sizes of the open-ring supporter to fit different ear sizes. It will be available in Spring 2018 in black and gold.
