As someone who appreciates high quality sound and wants that with the convenience of multi-room functionality that Wi-Fi streaming provides, this speaker system is an absolute revolution.
It says a lot about the situation that I spent way less time setting up the new system than I did taking down the old one. I estimate that I replaced more than 170 lbs of equipment with around 40 lbs that this pair of speakers (including built-in amps and etc) weighs. So much less clutter! Setup was effortless and effective, the sound is better (and it was previously quite good, until recently, when my old power amp died) and the functionality is spectacularly better. This system offers an extremely simple and direct route to decent to very good sound (better at the price than I could achieve with lots of careful effort over many years) and all the functionality that I, personally, currently want.
I used an inexpensive old subwoofer with the old setup. I continue to use it with these new speakers. I think I would be happy without the subwoofer, but like the tiny bit of additional rich low-bass and kick that it provides.
That points to something that astonishes me about this system. The KEF Connect app equalizer made it very easy to account for the situation of the speakers in the room and to incorporate the subwoofer. I'm a software developer, and think they did an extremely good job with the human factors of the app. I don't need or want the app to provide the functionality that my streaming music players provide – as another reviewer said, let Google and App and Tidal, Roon, etc do that. I'm very pleased with how well the app does what I need it to do. Similarly, the remote control gives me a convenient way to adjust the volume, mute, and on rare occasions when the I need to override the automatic source detection, change the source.
I haven't yet said anything specific about the sound, and I'm still finding out how it is. So far, I'm delighted. I'm finding more clarity, richness, and dynamics than I've experienced before in my home. I continue to go through different parts of my collection, as the mood strikes, and discover myself enjoying aspects of the music that I hadn't noticed before. People often talk about the almost palpable imaging that Kef's coincident-centers Uni-Q drivers provide. It's true, and it enhances the experience. The thing is, I haven't found any downsides. As I said, they're still new, there's more to discover. But I'm happy. (-:
I've only had the speakers for a few weeks, and am wary of an "all eggs in one basket" dependency on them. I will be dependent on KEF and/or after-market repair services if something breaks. That said, this is KEF's second iteration of the model, which could mean that a lot of the bugs have been shaken out. Plus I was in a bind with the old system when my power amp died, and that's the case for any component in the multi-component chain. It's all trade-offs.
Ultimately, I got a high quality, exquisitely well-integrated system. Provided that they're reliable, for anyone who streams music in their home, these are the best prospects that I've encountered for getting high fidelity and high functionality at anywhere near this price, more so than anything else I've seen up to now.

Insane sound quality and love the KEF app
I know this is overkill for the desk but I spend so many hours here I wanted the best. It came down to these KEF Wireless 2 speakers or a pair of Genelec speaker monitors. I wasn’t sure if the KEF would perform well in a near-field application but they image great and are not fatiguing. They are a great value for the money and connectivity is handled through the master speaker on one side. The KEF app can control our Tidal and Qubus music through the LS50 and our LS60 speakers in the living room. We use Roon to manage all of our music and it drives the KEF and Sonos speakers with ease. The iPad M4 allows us to easily access lossless music through the house and we like it better than Sonos. What great speakers!!!!
