Is your KEF LS50 Wireless firmware up to date?

The latest firmware is available for all LS50 Wireless owners to update their speakers.

The firmware is required for both of KEF’s new apps (KEF Control and KEF Stream) to function properly. Please ensure it is installed prior to downloading the new apps as older versions will no longer be supported. The KEF LS50 Wireless Firmware Update Tool is required to make these updates, visit the KEF Product Support page to download the programme. This programme will recognise what firmware your LS50 Wireless Speakers are currently running and will instruct how to update it if necessary.

  • Keeps speakers working at optimal performance
