This issue is definitely not solved as of April 28th 2024. My Era 100 worked fine until today when this problem occurred. Bluetooth connected, but there was no sound (unless i started playback from the Sonos app). I tried playback from several bluetooth sources, same problem. I spoke with Sonos support and the only way to resolve the problem was to do a factory reset on the Era 100. My Era 100 was up to date.

Too many times, the Era 100 will not connect to Bluetooth. It says connected via IPhone, but no sound. I called customer support, performed factory reset and still unresolved.  We will call customer support again - very frustrating.

I would just like to say this issue should have been resolved by now. Just about every other company on earth can manage to have functional bluetooth in their products. I am very dissapointed Sonos, your customers expect better. 

The issue remains. I had a call with Sonos support today (July 16) who informed me that their app (for ios as well as for Andrdoid) is very buggy and has issues with BT connectivity. Lost connectivity over BT with ios is well known it seems. And BT connectivity wirh Android is not supported.

The advise I got: be patient and wait, we'll fix it at some point.

A rather immature product in my view.

Issue remains still, got my era100 today and no luck with my sennheiser bt t100 and bluetooth. Spend couple of hours with customer support and nothing. I hope they fixed it soon!

I just want to keep this alive. It’s a significant user experience problem that needs addressing. Nearly 18 months on is not good enough. Bluetooth is the bare minimum of capabilities these days and Sonos can’t get it right. Never mind new headphones, let’s get a speaker that works. Really dissapointed with my Sonos experience in the last 12 months…. I miss my Bose

So i finally got it to work with my sennheiser bt t100, after maybe 3 times of resetting sennheiser and doing re-pairing with era100 it started to work. It was weird! So maybe theres hope after all.

Issue is still here.
Never ever again will I buy a Sonos product. This is ridiculous.

Was this ever solved? It connects to my MacBook but nothing plays. Someone please help. 

I’ve seen today that they’ve finally released an update patch that had a Bluetooth component to it! Hopefully it solves this problem. I’ll report back.
