Sonos One dead (cannot power up).

Return it to Best Buy, and get a replacement.

For what it’s worth, I’ve purchased the majority of my 24 Sonos devices from Best Buy, with the exception, if I recall, of four devices from Sonos directly. I’ve never had an issue, including the couple of ‘open box’ devices. 

Ditto for me too.  I had one One SL go out after ~8mo.  I was able to RMA that one.  I then had the second one go out 5 months later, and the RMAed one died a month after that.  The second one to go out was a month out of warrenty, so no luck there, and the RMAed one was noticed (we don't watch much TV) 2 days before I left on a 6mo vacation.  

Sad to see that these have almost no lifespan, and that Sonos doesn't stand behind thier products.  

Same here in Spain, my Sonos One (Gen 1) which has been working fine since bought in May 2018 has powered-off today and will not power-on; I’ve tried unplug/plug-in, different socket, different cable (from a still working Play:1) all to no avail. #AnotherOnebitesthedust! 

I’m new to Sonos and am completely disappointed in the quality (assurance) of their products at this point.  When they work … they work and sound great, but they seem to have a VERY short lifespan for when they work.

Same issue as others on this thread, only I’ve purchased two (2) Sonos One devices - one in April 2021 and one in May 2021 - from the local Best Buy.  The one purchased in April stopped working by May and the one purchased in May stopped working in June.  BOTH devices only lasted about one month before they completely failed to power up any longer.

I have a significant amount of tech and A/V experience and lots of both in my homes.  I only decided to try the Sonos One option for my one summer home as it seemed like a nice cheap way to test their tech.  Glad that I did because it failed miserably.

Glad I didn’t invest in the various other options.  Was planning to use Arc/Sub on three TVs in this home and use the architectural series for a bunch of in ceiling and outdoor whole house audio work in a new home.  Sticking with my other vendors who have worked solid for 5-10 years already for me.

Sad that Sonos can make products that sound nice, but can’t make them reliable or with a consistent quality.

I have owned over a dozen Sonos products going back to the original ZP80/ZP100 bundle.  Not one of them has failed.  Matter of fact, my S1 products are humming along just fine at a relative’s home.  

So be careful which anecdotal brush you use to paint so broadly.  

It’s odd, as my experience has been diametrically opposite of yours. I have 20 some odd Sonos devices, probably a third of them purchased as ‘open box’ items at Best Buy, dating back ten plus years, and have never had a single device fail. 

I’m sorry you’ve had such trouble. I do expect electronics as complex as Sonos to have a small failure rate, but it does seem egregious that it’s happened twice to you. 

It kind of sad that Sonos does not back the Sonos One. Mine too has failed after a very short period. I have read too many bad reviews.

I’m not sure I understand what you mean by Sonos not backing the Sonos One. The device is fully covered by the same warranty as all other Sonos devices. If it is under warranty, Sonos replaces it, if it isn’t under warranty, I believe they offer a discount in the purchase of a replacement device, something they don’t have to do. If that isn’t backing their device, I’m not sure I understand what is. 

Well Bruce, How many speakers have you owned in your lifetime that went out in just a couple of years. Most of mine would have lasted a life if I didn't think I needed an upgrade.

I live in a gated community and I handle most of the IT problems here. I sold a lot of Sonos here  with little problems. After hearing how a few of these went bad and Sonos will not replace them. I will not recommend these speakers.
