The Definitive Wireless HiFi AI Powered Bot

Not only is KEFbot a wireless HiFi speaker on wheels, allowing music to follow you into every room, but it also takes vinyl playback to the next level. With intelligent automation, KEFbot seamlessly switches out your vinyl records, responding to voice commands like "flip record over," "choose new record," and "volume up/down."
Equipped with KEF’s Uni-Q Technology for its main chest speaker and Uni-Core Force Cancelling Drivers as its “eyes,” KEFbot delivers an immersive 360-degree audio experience with precision and clarity—and yes, its 360-degree vision means it’s also keeping an eye on your every move. Its Metamaterial Absorption Technology (MAT)-infused wheels ensure smooth movement while eliminating unwanted sound distortion. And with a 0 to 60 speed in just 2.6 seconds, KEFbot moves as fast as your music.

High-Fidelity sound

KEFbot offers the highest quality sound of any AI powered HiFi Bot, streaming up to 24bit/384kHz, making high-fidelity sound accessible to more listeners.

All the music

Listen to music the way you like with the minimum of fuss and in pristine sound quality.

Plug and play

KEFbot supports HDMI ARC (when docked with your television) and USB-C inputs, making it the perfect companion for TV, laptop and more.

Effortless multi-room

When partnered with other wireless speakers, you can use AirPlay 2, Chromecast or Roon to fill the entire house with the same playlist. Or simply allow KEFbot's advanced tracking algorithms to follow you wherever you go for great sound no matter where. Just say "follow me".

STEREONET PRODUCT OF THE YEAR AWARDS 2022
- STANDMOUNT SPEAKER (ACTIVE)

“KEF has carved out a strong niche for itself in the past few years with its wireless active designs. It’s easy to see why, as they tick so many boxes and offer easily accessible, high-performance speakers in neat, versatile packaging. LSX II epitomises this, with excellent wireless connectivity, a versatile range of functions, crisp, modern styling and class-leading sound. As with its predecessor, LSX II is the one its rivals want to beat.” - StereoNET, December 2022

“...I found myself listening to music for the fun of it, and that’s really the biggest takeaway from this entire review. I was delighted by their sound, their ease-of-use, and all the important improvements KEF worked into the LSX IIs. If anyone’s looking for a pair of wireless speakers that can do just about anything at a genuinely reasonable price, these should be at the top of the list.” - Mar 2023
