KEF LS50 Wireless II - Active wireless stereo speaker system (Mineral White) | HDMI | Airplay 2 | Bluetooth | Spotify | Tidal

Product Information

Thanks to its HDMI, optical and coaxial digital, plus analogue 3.5mm inputs you can also connect up other sources, such as your TV, games console, CD player or turntable (with built-in pre-amp). Feature-wise, the speakers set up very smoothly using an iPhone, and within minutes you are able to stream to these speakers using AirPlay from your phone. It was a great setup experience. I like the touch-panel on the top of the speaker, but it is by no means necessary. The remote works well, but is not quite as well built as the speakers themselves. You can choose to operate LS50 Wireless II completely wirelessly at 24bit/96kHz resolution for a completely clutter-free set up, or you can connect the two speakers with the supplied cable for 24bit/192kHz resolution sound.

They don’t get five stars however because the quality of engineering in the speakers doesn’t extend to the app needed for streaming. When switching on the speakers immediately switch on from standby and start to play in a second or two. After a few more seconds they stop playing and the app opens a red bar asking me to select the speakers in settings. They are already selected and show as such. After a further variable wait they start to play again. I’ve learned that my intervention makes no difference, so I just wait. This can happen a couple of times before they settle down. Reinstalling the app makes no difference and it happens whether I use my phone or iPad. Sound-wise, these speakers are extremely balanced, with a good depth and soundstage. They are not too warm or too harsh, but sit nicely in the middle. They certainly produce a strong bass but do not go as deep as some speakers, so are pushing you towards adding a subwoofer. They control quite well at higher volumes. There is a good level of detail and presence, and the ultimate test is that I can actually close my eyes and sink into the music. For the money it's good. These sonic advancements are not only a credit to KEF's engineering but also representative of how far such speaker system concepts have come in recent years. Needless to say, we look forward to hearing more products using MAT technology in the future. We listen to Adrienne Lenker's Symbol and it is a more captivating affair through the Wireless IIs. The extra space between her vocal and the strings is in relative contrast to the originals, where it sounds as though they're fighting against one another for attention. That extra spaciousness isn’t at the expense of cohesiveness either – a hallmark quality of the Uni-Q driver’s tweeter-inside-the-mid/bass-cone design. I bought the LS50 Wireless II speakers, mainly to listen to The Archers and route large conference calls through. I never imagined or had any intentions of using them to listen to music through.You could own these KEFs and have little need for the dedicated app, considering the LS50 Wireless II support AirPlay 2, Google Chromecast and Bluetooth, and are also Roon Ready. Famed for their striking design, balanced sound and complete connectivity, the original KEF LS50 Wireless speakers swept the board. Now featuring new MAT technology for superior sound, a brand-new wireless platform and new KEF Connect app, the LS50 Wireless II is more impressive than ever. Audiophiles will be pleased with support for streaming files up to 24-bit/384kHz, as well as MQA and DSD256; but even if you eschew the wonders of Hi-Res Audio in favor of some simple Spotify streaming, you won’t be disappointed by the sound.

I am an old audiophile, brought up on components so heavy, you could only ever live in ground floor accommodation. The soundstage, the grip on the music, Jeff’s vocals bringing tears to my eyes, the depth of bass (no sub-woofer); everything from these two small boxes - really? Yes - really! As a product following in the footsteps of such a huge success, the KEF LS50 Wireless II arrive with a world of expectation on their shoulders – but they well and truly meet those expectations. Make no mistake, this is a sequel of rare quality.Solid all-rounder I'm using these in a smaller room as desktop speakers, and I wasn't sure if I would have enough space for a separate amplifier. In the end I decided on the all-in-one solution to save space. The effect of MAT is clearly heard in the cleanliness of the treble, although the difference in purity can be heard across the frequency range. Mids are cleaner-cut and bass more defined, their extra refinement making the originals sound a touch crude. The whole presentation has been opened out, that extra room not only filled with subtler, more precise detail, but also allowing for greater instrument separation that makes its delivery sound much less congested in comparison. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT™) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
