Roam Stereo Pair issues

Ugh.  Super frustrating.  I have the exact same issues.  I have 2 Roams in my kitchen and want stereo sound. (Speakers are 10 feet apart I never move them) Nope, inevitably sound will come out of one speaker after a while. 

 I have created the pair 20 + times, done a factory reset.  Firmware is up to date. 

I have an other room set up with a beam , ones, and a sub and that always works perfectly but can’t get reliable stereo sound out of my brand new and pricey Roams.  
 Come on on Sonos!!  You need to do better  ! 

Yes i Have the same issue, every morning the stereo pair disappears, and the devices are plugged in and I never turn them off, it’s really quite annoying. It doesn't happen with any other devices (the sonos ones for example)

I have exactly the same extremely annoying problem. So far it seems I have to reestablish the stereo pairing just about every single time I use the Sonos Roam speakers.
I was able to get ahold of the Sonus customer support. The Sonos technical support person I talked with said the issue with the Roam portable speakers losing their stereo pairing is a known issue. He said that it would be noted on my open ticket but it was not clear if they plan to address this issue or not.

I found that If the Sonos Roams get separated from another the stereo pairing is broken, if they are put in standby the stereo pairing is broken, if they switch from Wi-Fi to Bluetooth or back again the stereo pairing is broken and if they hear the Alexa wake word and respond the stereo pairing is broken . It makes them very awkward to use and I can think of at least three different ways that This could be fixed.
Basically the SONOS technician said this is a known problem and to be expected for a portable speaker.  The Sonos play ones are essentially the same except they have an external AC power supply yet they don’t Have these problems with the stereo pairing being broken If they’re moved, unplugged, or any other condition.  I would put the roams at only a 2 out of 5 because of this annoying problem.  

Another thing I’ve noticed is that the play time of 12 hours is only true if you don’t forget to turn the speakers to standby mode when you’re not using them otherwise they gradually drain down to zero. And of course if you put them in standby mode the stereo pairing is broken.

I too found the same issue and very disappointed since I intended to mostly use a pair in stereo! I absolutely love the quality and features of the Roam for my use, but as written in the prior post, “I was able to get ahold of the Sonus customer support. The Sonos technical support person I talked with said the issue with the Roam portable speakers losing their stereo pairing is a known issue. He said that it would be noted on my open ticket but it was not clear if they plan to address this issue or not.”, I also contacted customer service and got the exact same response.  I didn’t feel confident (even after it was acknowledged they are aware of this widely-known issue/complaint) that they are going to do anything to make it better.  At least there was no sense of any commitment.  As such, I may have to join the group of folks returning the second unit since I don’t need two, except for the purpose of stereo pairing, and having to set up every time I want to play music is a real pain in the (well you know) and not for me.  (Not to mention each time I do that, my Alexa notification of the unit joining the Alexa skill is annoying).  Sure wish it could have turned out better, but not giving up hope for the next few weeks while I remain within the return period.

My use case is two Roams in the bathroom, one plugged in and the other on a Sonos charging base so I can pick it up and take it into the shower, then put it back on the base afterward, so both are left always on.

I had the same issues as above when one Roam was allowed to go into standby, or if one was taken away from the other as I did when I got them and was trying them out - which I sort of understand and can definitely live with.

I soon discovered that leaving both powered on and on charge so they don’t go into standby solved the issue - until the past week or so. Now the stereo pair breaks after around an hour of the speakers not playing even when they are both left untouched and powered up, just like they have been for the weeks since I got them on launch day. It’s nothing to do with Bluetooth, using Alexa or any other of the theories above as it happens when the bathroom is unoccupied and the speakers are not touch or interacted with in any way.

I have zero interest in a portable Sonos speaker - I just wanted a waterproof one so I could take it in the shower with me to listen to audiobooks without having to have the volume up loud enough for neighbours to hear through the open window, and bought a pair so I can hear the book when I move out of the shower, and so it sounds better when my wife uses it for music.

The behaviour of losing stereo pair when on standby was a bad enough experience (I couldn’t leave one speaker in the shower except when charging as I had planned to do), but regressing to breaking the pair regardless of what I do pretty much has me regretting buying the Roams - and that as a happy Sonos user of over eight years with 13 other Sonos products.

So why not submit a diagnostic, and call Sonos about it?

Again, I agree, and I didn’t buy two for the purpose of portability, but rather I was impressed with the size and sound (always a Sonos plus for me) and where I intended to use them.  I even intended to accept “plugged in all the time” if it would work, but tech support told me that would severely diminish the battery life by doing that, so that was a non-starter, and like you say, without sound they eventually sleep, as they should. So, I have seen no movement by Sonos to make a change or even commit to development, other than customer support “opening a ticket” for consideration by the developers, with the caveat, “but there is no guarantee they will act on it” as I was told.  As such, I will returning the second one and accept no stereo for me. (Except in other rooms where I have One’s and One SL’s paired). BUMMER!!!!!

Add mine to the chorus of voices Sonos apparently doesn’t care to listen to with regards to problems stereo pairing two Roams.

It’s not even something I want them to do very often. Typically, they just sit in different parts of the home. But we’re leaving on a road trip, so I thought I’d pair them as stereo and take them as a mini-system on the road for two weeks of travel. That’s not going to happen.

The two don’t even stay paired for longer than a few moments. Tried it on an Android device as well as an iOS device, to see if it might by software related. Fails on both Android and iOS within moments after initially announcing success in pairing two speakers, quickly reverting to playing music only through one speaker (the one, incidentally, it plays the chime through in the pairing process).

Pairing two speakers as a stereo pair is something Ultimate Ears had down *years* ago. Very disappointing that it clearly doesn’t work well, if at all, on Sonos, given the considerable premium one pays.

I am having same issue with dropping stereo pair as well. My roams are connected Wi-Fi, and seperate every time I turn them off. The do connect back without any issues. It is annoying but I do hope Sonos will address the issue. 

Same for me.  I had hoped for a while that a recent update (13.1.1) may have fixed it but again today my Roams went to standby, then show as Offline in the S2 app.  When they show back online they show as individual speakers.  The pairing process is quick but potentially I would have to do it every time I want to use them.

Keeping a portable battery powered speaker on charge all the time is not a solution or even a workaround.  It spoils what is otherwise a great little speaker.  Well the other issue is likely to be the poor battery life.  I thought I was getting 5 days on standby then revised that to 4 and now I think that might be optimistic.  I would be interested to know how Sonos can claim it lasts 10 days on standby.
