A:Answer They are two different "systems". The sonos is not a speaker, it has a built-in controller and amp, too. You can use the Sonos app to control it. The Bose piece is a controller without a speaker/amp. It is like using the Sonos Connect (not Connect Amp) which is a controller with no speaker or amp. I won't say there is no way for you to connect the Bose piece to the Sonos, because although it makes my head hurt trying to think about it, you "may" be able to connect the Bose to the Aux input of a Sonos Play 5 (not a Play 3 or Play 1) into the Aux input, but you would have to use two apps and bounce between them, You'd use the BlueTooth in the Bose to allow you to feed your phone or tablet into the Bose piece, using the Bose app to control that, then switch to the Sonos app to get the Sonos Play 5 playing the "Aux" input. But... that would be a nightmare to control and if you do not have a Play 5, it wouldn't work as the lower models have no Aux input. If you really, really need the BlueTooth option, I'd recommend you give up on the Sonos and start adding Bose pieces (they have Soundtouch players that are similar to the Sonos Players as the amp/speaker/controller are all built into one piece. We use the Sonos most of the time unless the user really needs the Bluetooth capability, or needs the presets that the Bose offers, in which case we use Bose. Often a person has several rooms with speakers, so we can just add a few of these Bose pieces and attach each to a 2, 4, or 6 zone amp that has an input for each zone.
