I surprised no one has talked about how incredible Sonos is! It isn't portable in the sense that you can take it to the beach, but you can unplug it and move from room to room in your house. The sound is better than the Bose, at least in my opinion. You can get a play1 and it has plenty of strength to fill a room with gorgeous sound.
I know it kind of sucks that you have to buy a bridge that connects with your home network to make the speaker truly wireless, but if you contact me I can send you one for free. Just let me know!
Probably because the OP is asking about two specific items. The Sonos is not portable in the way the bose is. Also Sonos gets into big money pretty quickly
