So you want a Bluetooth speaker then? These do exist you know lolAnd that's what we're trying to say: it's permanently tethered. I guess for some people that's fine. I think two of them would be great on our deck in the summer -- except there are no electrical outlets out there. Even moving the minis from room to room requires first fishing for the cord and then plugging it back in somewhere else. If it had a battery (and I have two other wireless speakers about the size of the minis that do -- and that last up to 30 hours), then I could just carry it to wherever I needed it. But I guess if the mini is aimed to be part of a smart home system (rather than just a Bluetooth speaker) then it sort of makes sense that it would need to be continually plugged in.
Also you can always plug it into a power bank if you really wanted to do that
