Portable Speaker?

No

They have the 1, 3, 5 and Playbar for TV sound.

The Play 1 could be considered portable but it doesn't have a battery and doesn't claim weatherproof.

Sonos won't pre-advertise any product intentions but the consensus is that a battery powered Sonos speaker is highly unlikely

Too bad. I think there would be a market for that among the Sonos community. I understand that they operate on a wireless platform (as opposed to Bluetooth - so you couldn't take it to the beach), but it would be nice to have the freedom to utilize a speaker in your garden, shed, backyard - anywhere within range of your home wifi signal.

But if it's in range of the home Wi-Fi it's in range of a power extension cable. I'd be surprised if Sonos produce a portable speaker.

I suppose that's true. But wires and cables so darn clunky!

Phenomenal listening experience

Consider doing what I have done - a good quality weather proof bluetooth speaker, an old out of use 32gb iPod touch loaded with all my favourite playlists. Once past that one time investment of time and relatively little money, music on the go wherever you can go in whatever weather you can take. Sound quality that is very acceptable and a solution that I don't see Sonos offering, so this workaround is very useful to me in spite of having permanently installed outdoor speakers that are Sonos fed.

I have to agree that a nice, high quality, rechargeable Sonos speaker that's about the size of a Play 1 would be amazing. I cannot imagine why they would not already have this in development. It's absurd to run an extension cord into the yard or gardening shed or to have an electrician install a plug in just the right spot on our deck simply to power one speaker once in a while... I can't imagine why Sonos would snub their nose at this opportunity to truly become "wireless"..

I would also thank Sonos if they take that step; I have several speakers in my system (including the CONNECT-AMP+wire+outdoor speakers in the garden solution 😃 ) but I think a portable, rechargeable speaker (if possible, smaller than PLAY-1) would cover some of my needs (ie. shower, occasional work in the garage...). I would not prioritise sound quality in this particular speaker, but I would love to have it integrated with the rest of my system!!

Until the time Sonos gets around to doing this - if they ever will - the easy availability of music via streaming services means that these needs can be met right away by one of the many and now quite decent sounding bluetooth weatherproof portable speakers available. It can then be just as easily used on the road, out of range of Wifi or mains power, with music downloaded to the phone for such listening.

Every time I talk to a client about Sonos this comes up. Every. Single. Time.

It's just expected, and both a surprise and a disappointment to them that it's missing from the range.

Yes, as an installer I can work around this in various ways, but that still doesn't change the fact that from a new client's perspective they don't understand why something so good indoors hasn't made the short step to outdoor entertainment. An equivalent to the Arcam rCube but with Sons Wi-Fi and back-up Bluetooth is such an obvious product.
