Britain-based KEF manufactures innovative audio products for outstanding sound experiences. One of their most popular products is the KEF LS50 Wireless, a state-of-the-art, complete home music system that delivers high-resolution audio.

  • Designed and developed iOS and Android companion applications for KEF LS50 Wireless speakers
  • Created a single center of control for speaker and equalizer settings, volume and media streaming
  • Integrated music streaming services and support for remote media servers

The idea

KEF planned to launch an active version (with crossover components) of their LS50 Wireless speaker, and wanted to develop a mobile companion app for Android and iOS devices. App users should be able to manage the speakers’ settings and properties from their mobile devices. They should be able to set up the speakers on their home Wi-Fi network, and use the app to control streaming functions and playback functionality. KEF also wanted the apps to enable streaming and integration with Universal Plug and Play (UPnP) servers. In essence, KEF wanted to deliver a rich, multi-dimensional soundstage experience.


KEF reached out to Star to leverage our design and development expertise. We designed and implemented companion mobile apps (Android and iOS) according to KEF’s specifications. The apps give users complete playback control, flexible sound adjustment and music streaming. We used UPnP protocol capabilities to enable wireless content streaming to the speakers, and integrated TIDAL (the high-fidelity music streaming service) so users can access their cloud-based music libraries directly through the app.
