Okay, what can I say.
Sonos = quality.
I had read a comment about its bass and that I shouldn't get the subwoofer before listening to it.
They were absolutely right.
Incredible sound, very powerful bass.
You get what you pay for.
You can tell the quality from the packaging.

It was the initial piece of the whole audio system. I intend to buy the subwoofer and maybe two small ones later to complete...

Unbelievable sound. Do not buy the sub before you hear it on its own. It does the job very well for which you will buy it and much more. It's worth every euro you will spend. One of the best purchases I have ever made. Children, buy it with your eyes closed.

Very clear sound, especially for the TV. Music and movies are flawless. Of course, it won't break the windows. For that, you would need to get the Subwoofer. But even as it is, it's enough for me—we have neighbors, let's not forget. The surround is very good but not like a home theater 5.1. As we said, it's a sound bar; otherwise, you would have to get the Sonos One and the Sub. And then you would have the ultimate home theater, but of course, the cost would be high. It has a night mode setting if you have a problem with the volume, so you can raise the voice without losing much of the effects. You need to have HDMI Arc on your TV. Most TVs have it, even old LCDs, and then with the TV remote, the bar turns on/off automatically. I have also connected Apple TV 4K, and with its remote, the bar also turns on/off. Perfect cooperation—you can use any remote you want and control the volume. You download the Sonos app (Android/iOS) and set it up only from there! It doesn’t have its own remote. In the app, you’ll also find internet radio stations; I’m in Thessaloniki and it found them all. The good thing is that it works even with the TV off—very nice for internet radio at home! It also provides other settings for both Android and iOS. There is just one extra setting only with iPhone. It uses the iPhone’s microphone; you walk around the room with your phone and the bar auto-calibrates to understand the space it’s in. If you don’t have an iPhone, you can borrow one and set it up once; after that, you don’t need to do it again unless you move the bar. Bluetooth works perfectly from your phone—you can send anything to the bar! I am very satisfied! Especially with Netflix and Apple Music!!

Flawless! After 5 years of use, it lacks nothing in terms of technology!
Music playback via Bluetooth works perfectly from both Android and iOS/MacBook devices.
Voice commands elevate the experience: finding radio stations, adjusting volume, turning the TV on/off, and many more functions—all work perfectly and without delays.
Through the app, you can select and set up which music platform you want to use. Personally, I use Apple Music and TuneIn Radio.
The sound is sufficiently loud, ideal for a nice party at home!
I have the system connected to a Sony OLED TV via HDMI e-ARC, and the performance is excellent!

It's really great, it has a very full sound, okay Sonos is considered the "apple" of the music category.
The only thing that bothered me a lot is the difficulty of connecting to a computer, because it only has one HDMI port, so you have to choose if you want it only for the TV or only for the computer. Despite that, it's amazing in terms of quality.
I have to add the ease of connecting with any device you have with the Sonos app. Very simple and easy.
