TOKYO – April 11, 2018 – LINE Corporation (“LINE”) announced today that its AI assistant Clova will be implemented in Xperia Ear Duo, a wireless open-ear stereo headset by Sony Mobile Communications Inc. (“Sony Mobile”) slated to go on sale April 21 in Japan.


When LINE initially announced the concept behind its AI assistant Clova in March 2017 at Mobile World Congress 2017 – the world’s largest mobile telecommunications trade fair – the company also announced that it was engaged in a joint development project with Sony Mobile.


Sony Mobile announced today that its wireless open-ear stereo headset Xperia Ear Duo will go on sale on April 21 in Japan.*1 The Xperia Ear Duo provides users with a new “dual listening” experience, allowing them to hear both their surroundings as well as music and other sounds coming from their device. It also includes an assistant feature that allows users to carry out various operations using just their voice or head gestures.

Thanks to its implementation of LINE’s AI assistant Clova,*2 the headset allows users to send and receive LINE messages hands-free even when they’re on the go. The integration allows users wearing the Xperia Ear Duo to enjoy hands-free communication, such as entering and sending messages over LINE, by carrying out operations with just their voice and head gestures, all without having to touch their smartphones. This was all made possible through voice recognition and head movement sensing technologies.

*2: Only available on Android.


Furthermore, in addition to sending and receiving LINE messages, this Clova implementation also opens up possibilities for users to use various other LINE services. Whether at home or out and about, users will be able to utilize various features including LINE Music, LINE NEWS, and translation features,*3 giving users the ability to listen to their favorite tracks from a library of over 43 million songs, get news briefs, and more.

*3: Though these are a part of Clova’s normal skill set, not all skills are supported.


Not only is the Xperia Ear Duo the first product created by an external partner in Japan to implement Clova, it is also the first to expand Clova’s use cases into the mobile scene. By seamlessly connecting Sony Mobile’s top-tier product development capabilities with LINE’s 73 million users,*4 the companies believe they will be able to provide a superior user experience and plan to continue to add even more Clova functionality through software updates going forward.

*4: Monthly active users; current as of time of publication


LINE believes that there are many possibilities available for Clova to grow beyond smart speakers and out into the world – whether it be around the home, in the car, or elsewhere on the go – to make users’ lives all the more fulfilling through its audio experiences. The company will continue to actively consider partnerships with external partners and build on the conveniences offered to users by the Clova-enabled voice operation functionality.
