I have the Gen 2. An amazing speaker in every way, I wouldn't trade it for anything.
I also bought a column-type speaker from a well-known company, thinking it would be better than Sonos, but it doesn't stand next to Sonos in either bass or music clarity.

Audiophile sound, clear highs, full mids, and bass that gets you moving. Easy to install, plays everything, and the app is a breeze. The 3.5 mm line-in works through the Sonos App. Trueplay tuning adapts the sound to the room, using an iOS device to ensure the best possible acoustic experience. Worth every euro! Premium listening experience. Buy it!

Very high-quality construction and meticulous aesthetics. It connects very easily with the application but cannot connect and simply reproduce sounds outside the application.
Good sound fills a space of 60 square meters very well and with strong intensity.

Perfect speaker with the worst concept and software. If you think you can send any sound that your mobile produces to the speaker, you are mistaken. Only with its own software and its limited capabilities can you listen to music, i.e. music that you have locally downloaded on your mobile and internet radio stations. You cannot, for example, watch something on YouTube and pass the sound to the speaker!! Also... Do not dare to change the router in your house. Endless trouble and it is most likely that you will end up with an expensive paperweight instead of a speaker. The controlling software is not able to recognize the speaker again and integrate it into your account even after a factory reset. It is preferable to buy a Bluetooth speaker.
