Sonos, constraining sound for the displeasure of listeners -- and please don't dare update an old product or you'll lose everything.

Other than the quality of sound and assortment of apps, what real services are provided for listeners? It’s a shame the list does not go on, and simply ends there. It’s a product that doesn’t allow use without Wi-Fi and doesn’t have an option for headphones. I’m proud to have persuaded fellow friend from indulging in the same misadventures I have when it comes to buying constrained speakers. Why have rules or limitations on sound?
