Sonos Roam Flashing Red Battery Light

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

Best accessory for the Sonos Roam.

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

I have ditched all my other speakers for SONOS , i own the entire collection except Roam!!!

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

I bought this a month ago when the battery died (I unfortunately did not notice the low battery flashing light indicator). The replacement battery arrived very promptly, was easy to install, and my backup is operational again — and just in time because a tornado hit here a few days later and I lost power for 8 hours.

but it is unsettling to have the upstream light flashing

Recently bought after comparing to UE Mega Boom and Sonos Roam. Pairs easily and sounds great. I also like that it floats. Feels very sturdy. Charged faster than some reviews I read - Charging is not a negative compared to others in its class...

We are so taken by the crystal clear sound that we ordered more speakers. We now have 5 speakers, The 5, two Sonos One's, The Move, and The Roam. When all these play at the same time it sounds as if we are in a concert hall. Great speaker and great customer service. Thank you, Victor
