- Better: treble smoothness and handling bright recordings The LS50 Wireless II is described as handling over-modulated treble issues more easily than the LSX II.
KEF LSX II Wireless HiFi Speakers Review
Bottom Line
Choose the KEF LSX II if you want compact wireless speakers with sharp imaging, easy setup, strong streaming, and stylish design. Skip it if you need theater-style surround, deepest bass without a sub, premium controls, or effortless high-volume smoothness.
Best for
Best for listeners who want compact, stylish, app-friendly hi-fi speakers for a desktop, small room, bedroom, kitchen, or stereo TV setup. The evidence especially favors people who value imaging, clarity, and simple streaming over component stacking.
Not for
Not for buyers who want true surround effects, Atmos-style immersion, very deep bass without a subwoofer, or premium physical controls. Large rooms and high-volume movie use also expose the limits of the small cabinet.
Verdict
Across the reviews, the KEF LSX II stands out as a compact wireless hi-fi system that sounds bigger and more precise than its size suggests. Reviewers repeatedly praised its stereo imaging, detail retrieval, easy setup, app-based tuning, and broad wired/streaming flexibility. The strongest tradeoff is that the small cabinet cannot fully escape physics: bass depth, cinematic impact, and high-volume smoothness improve with careful placement or a subwoofer, while the remote and lack of on-speaker controls feel less premium than the sound. Within smaller rooms, desktops, and TV/music setups that value clarity and simplicity over full theater immersion, the evidence points to an unusually polished all-in-one speaker system.

LSX II LT model

- Older model: setup and wireless update convenience The LSX II is presented as an upgrade from the original LSX because setup and updates no longer require tethering.

Remote opinions were mixed to negative: one reviewer liked the ergonomics, but others called it cheap, plasticky, limited, or only situationally useful.
-
Bluetooth range received a qualified assessment because the older Bluetooth version made the reviewer wish for Bluetooth 5.0 range benefits.
-
Chromecast was the main casting weak spot, with one reviewer reporting unusually slow track loading.
-
The main multi-room limitation was that synchronized multi-room playback was not available in the KEF Connect app.
-
Surround immersion was a weakness in the one direct mention, with the speakers not delivering Atmos-style or DTS:X-like effects.

The strongest themes are stereo imaging, instrument separation, detail retrieval, tonal balance, and a cohesive presentation that sounds larger than the cabinets suggest.
