The Biggest Small Music System

The incredible LS50 Wireless delivers clear, transparent sound that redefines what is possible from an integrated system. Designed to become a part of your lifestyle, LS50 Wireless proves that hifi does not have to be a chore. The critics agree, with LS50 Wireless being proudly inducted into What HiFi's Hall of Fame.

Immerse yourself in sound

LS50 Wireless benefits from KEF's near-six decades of experience in acoustic research and design. The crowning achievement is the signature Uni-Q driver array, providing beautifully natural sound to every seat in the room. Perfectly matched electronics provide the engine for the Uni-Q, ensuring that every detail and every ounce of power is recreated, elevating the experience from listening to being there.

Less time setting up, more time listening

A few minutes and the KEF Control app is all it takes to bring life changing musical experiences home. With integrated electronics, including 230w of amplification in each speaker, the guesswork of equipment matching is removed. A vast array of inputs ensures that you can connect almost anything you can think of - even a turntable, for the ultimate expression of the vinyl revival.

Ultimate Flexibility

Adjust how the LS50 Wireless sounds using a selectable EQ tuned to compensate for different mounting scenarios, creating more options for placement and positioning. Regardless of placement, Uni-Q technology disperses sound evenly for total listening enjoyment.

Comprehensive Connectivity

Connect a huge range of devices with LS50 Wireless' broad range of connectivity options, including 2.4GHz/5GHz Dual-band Wi-Fi, Bluetooth 4.0 with the aptX codec, Asynchronous USB Type B, TOSLINK Optical, and RCA Analog. Connect up to 12 devices in total, including a maximum of eight Bluetooth devices and switch between audio inputs conveniently.

For every room and situation

LS50 Wireless ensures that anybody can bring great sound into their life. The instantly recognisable shape is not just a design choice, but an acoustic feature, solidifying KEF's holistic approach to acoustic and industrial design. Available in Titanium Grey, Gloss Black and Gloss White, you can make LS50 Wireless stand out as much or as little as you want.The choice is yours.
