There is no amazing quality and the sound is unparalleled. The bass that this speaker produces in relation to its size is something else, competing with floor-standing speakers.

Good evening guys,

The above speaker was given to me as a gift. It has an amazing sound performance.

I just wanted to clarify that it can only be connected via WiFi and cannot function as a computer or TV speaker.

I thought about it a lot, that I couldn't use it as a speaker that can be connected to my TV or computer, so I went and exchanged it for the Sonos Era 100 which also has Bluetooth connectivity.

If someone wants to use it exclusively to listen to music like in traditional sound systems, it is a good choice.

If someone wants the option to use it as an audio output for movies on the TV, etc., it's not worth buying, at least not on its own.

The sound is perfect... it's just that the Sonos app is quite difficult to use.

Without windows rattling, the sound of it for a room up to 25m2 is ideal in intensity with crystal-clear clarity. It might want a little more bass. Sonos quality!

Amazing, and the amazing is subjective for everyone, I will proceed to a second one for purchase, something last for those who want to buy it, currently it does not support voice commands from Alexa and Google assistant in Greece, after contacting Sonos company they replied future but not for when because we don't know, however I can't understand why it doesn't accept voice commands from Alexa and Google assistant while even on mobile phones voice commands work normally, anyway, that's it

It produces very high-quality sound.
Even at high volume, the sound performance is crystal clear.
It is expensive but worth every penny.
