I considered buying my two adult kids a new Sonos Roam each, but these speakers are designed to last only a few years, because the battery is not replaceable. Sonos, you need to be a responsible global citizen. We cannot keep polluting this planet the way we have been, particularly over the past 50 years - the period of turbo charged, rampant consumerism.
You can change the design - allow simple battery replacement; and make the speaker, all your speakers, fixable. If the water resistance goes out the window, so be it.
Market your environmentally friendly credentials then. Put people and planet before profit, and you, and all of us, will profit in the long run.
