Alexa Multiroom music simultaneously on Sonos and Echo devices

Agreed. I’m going to return my Sonos Beam and Subwoofer and get Bose if Bose already has this.

I'm adding my voice to the resounding appeal for Alexa 3rd party MRM integration on Sonos products. My new Ecobee thermostat got me interested in voice control. I started with one echo device, an echo dot driving my B&W MM-1's. That system displaced the Airport/Beosound 3000 configuration in our kitchen/living area, the convenience of streaming and voice control means we listen much more now. Digging out the B&O remote and a streaming device+app to control the system and stream music just had too much friction for everyday use. A second echo was soon added in our TV area to control heating and stream music to the relocated Beosound 3000.

So I decided to dip my toe in the water and try voice control speakers with better sound quality built in. In my ignorance I assumed Alexa enabled meant, just like an Echo, but with better sound quality. So I bought a Sonos One for our den and a Bose Home Speaker 500 for the bedroom. The Bose went back after a couple of weeks even though I loved the device, and it's sound, because of it's crippled Alexa implementation. I want all of the convenience, voice queries and web knowledge, smart home control, music streaming, stereo and mono music, intercom, calling and messaging. Specifically for the bedroom Bose, it let me down by not implementing Music Alarms/Timers (& MRM) and BOSE could give me no info on plans to support them; my $20 clockradio has handled those for over 40 years. I almost swapped it for a pair of Sonos One's but it has the same limitations so instead I chose a pair of the Echo Plus Gen 2's.

I want whole home coverage using devices at a range of price points appropriate to the location, I'm not putting a $500 Bose in every room. I might use a Sonos One everywhere but I don't want to be locked out of ANY voice/smart functionality. In addition, while I'm using Alexa now, I want a path to switch voice platforms in the future if I need to without replacing all my high quality sound and entertainment system components. Maybe the solution is to go with cheaper voice control speakers everywhere and integrating higher quality sound and entertainment devices in entertainment spaces. But I still want whole home and zone MRM and all my devices/stereo pairs/zones/groups need to be compatible with all smart control functions e.g streaming alarms/timers, any available streaming service/program source. I.e. I want no functional limitations because of brand choice.

I'm starting to look at home cinema sound now, but it needs to fit into a home wide MRM system. So with their recently announced support for Alexa MRM, Polk Audio would be the front runner.

Echo Dots and Sonos seems to meet your needs pretty well. Life is never perfect.

+1 for this feature!

I am reequiping my home and my holiday house with multiroom in the very near future, and this MRM integration will decide which brand I'm going into.
Love Sonos, but lacks two important things for me now, MRM and handling two locations by saving all data in the cloud, and not only locally in the speakers.

Any update on MRM on the Beam? Thinking about returning. I mean how is this not the next top priority? Does anyone know about other sound bars that support MRM? Does Bose support it?

Sonos hasn't announced anything around this. I'm not aware of any multi-room speaker systems that play in sync with echos, although there are standalone speakers that will play in sync with echos. I haven't really done any research on it.

As to how it's not the top priority...it's up there on the list of requested features, but I wouldn't say it's clearly the most requested feature I've seen. It's also not one that I think Sonos upper management is all that interested in as Sonos makes money by selling Sonos speakers to fill out your system, not by making it easier to fill out your home with echos or other speakers. Perhaps some people my by Sonos for certain rooms if they can fully integrate with echos, where they wouldn't buy Sonos otherwise. More likely though, people will buy an echo for a room where they would have put a Sonos speaker.

There's also possibly some technical regarding how such a feature would operate with Sonos grouping functionality, differences in audio quality, and the fact that Sonos supports many more services than Amazon does.

Why would you use a streaming service, like Google that allows you to store your own music files in the cloud? And Sonos does not store music files on the speakers, it only stores file location and an index of your local music. I personally prefer using a music service rather than my own local files, but in your situation, I'd store the files on a portable drive I could take between the two locations.

Just found that the Polk Command Bar supports multi room. Guess that's the leader until the race finishes between Bose and Sonos and that will dictate which direction I build out my system with.

The Command Bar isn't part of a Polk mult-room system. It's a single bar + sub...stand alone. You can't even add surround speakers as far as I can tell. So my statement above still stands.

It also doesn't appear to be airplay 2 compatible, limited streaming services. Does have bluetooth and DTS though.

Not knocking the product, just pointing out that it's actually a rather different product then Sonos speakers, with a significantly different feature set.

Yeah, but my TV is airplay 2 compatible and everything else can just be triggered off of the Echo Plus which would be synced to the sound bar. Not sure what I'd be missing out on.
