Ace headphones not charging

Got my ACE headphones today, they sound great but they’re not charging. Stuck at 53%. Tried different cables and power adapter that work with other devices. Feel like I’m doing something stupid. No orange or green lights to indicate charging status. Blue light comes on ok when connected via Bluetooth. Is there reboot / reset option of some description I could try???

Thanks

I just wanted to chime in, I use the Anker Ganprime chargers (67w minimum) primarily for work and home. I first noticed the ace not charging after I had it pluged in, for a few hours and the battery depleted. I have not tried the factory reset, since there was the day one update, but I did find switching to a generic USBC 14w charging brick, that it is currently letting me charge without the reset. I'm curious to know if those that have done the reset if they are able to use their "fast" charging bricks and that it's a software fix rather than a power limit issue.

And I'm only stating facts. Whether you were repeating some information from the Staff or not. Also, just because it came from the Staff, doesn't make it true. I (and so many other people) have proven and demonstrated that that information is false.

I have contacted support separately. But I'm also going to keep sharing real life experiences here and other channels on the internet to inform others.

Then perhaps remain unbiased and include in your posts that some PD certified chargers do work - as that’s the truth of the matter too.

I'm not sure if you're joking or lacking something. I have included in my very first post on this thread and a couple of followup posts about chargers that DO work.

You're the one looking like you have a weird bias here.

Bias? - I have simply posted the information I have gathered - if you think thats wrong, then so be it. I also have acknowledged earlier that some users have mentioned their PD certified chargers were apparently not working with the Ace, namely some Anker and Belkin chargers. The PD certified chargers that I have here, do work… and I’ve posted links to those chargers in my earlier posts.

I’m also trying to help here by suggesting those who have a PD ‘certified’ charger issue (of whatever make/model) that do not work with their Ace, should perhaps contact Sonos to allow them to investigate the matter… I’m not sure where bias comes into that but again, if you think I’m being bias then that’s your prerogative.

I only pointed out your apparent bias as you mentioned this "I'm also going to keep sharing real life experiences here and other channels on the internet to inform others”. I was just suggesting you also include the fact that "some PD certified chargers do also work with the Ace”… as that clearly is the truth of the matter aswell and helps to remove any bias, when you do keep sharing your ‘real life experience’, as you put it.

Sure here it again. Everyone, heads up!

It appears that Sonos Ace is not PD compliant. Only use chargers (whether it's PD compliant or not) that can output 18W or lower.

Had Sonos Ace properly supported PD, it would have been able to regulate the charge it receives. But it can't. And that's actually quite embarrassing in 2024.

Do not bother contacting support or even go through the hassle of factory reset. It's not going to do anything. Because it's likely caused by a hardware skimp-out done by Sonos.

Some chargers like the Apple charger for MacBook Pro (I've tested 70W, 96W, and 140W) do work. Google chargers (I've tested 18W and 30W) do work. And any old chargers with USB-A port do work as well.

However, some PD chargers like Belkin's 65W and 40W ones do not work. Because the lowest wattage they can output is 20W, and as I mentioned above, Sonos Ace can't regulate that.

So yeah. 18W or lower.

And just to perhaps compliment the above this 100W "PD certified” charger that I purchased from Amazon which will happily charge two Roam/Roam 2’s simultaneously, or two Move/Move 2’s, and I believe it will also charge two Ace headphones simultaneously aswell, or you can mix ‘n’ match two of those products with the charger.

Note I have only tested it with two Roams and Moves mentioned (both generations), however I have only personally tested it with one Ace so far, as I just have the one pair of headphones only:

https://www.amazon.co.uk/gp/product/B08CVFMGL1

Note the cable that is supplied with Roam (gen1) is USB-A to USB-C, so that requires a different cable for the PD certification.

I’ve attached a couple of perhaps helpful photos too.

The charger will also charge an iPhone/iPad simultaneously and I use it to charge Android devices too, so it’s quite versatile, but it is auite a bulky charger, compared to many similar mobile device chargers.

Just so everyone knows, I think it’s PD compliant. Used my 100W Anker and have had no issues.

That's not how to look at it. Your 100W Anker charger probably has the ability to output 18W or lower, hence it works for Ace.

It appears that Sonos Ace is not PD compliant.

Wait is this actually true or mostly speculation? Anyone else confirm? I’ve been reading posts here by some that say the issue is that some chargers like the ones from Belkin and Anker aren’t actually PD certified and that’s the problem.

Just my speculation. The Belkin and Anker chargers seem to be PD certified according to their packaging and label on the charging bricks.

Furthermore, I've tested these chargers on so many other devices (cameras, tablets, laptops, phones, earbuds, other headphones), and the issue only happens with Sonos Ace.

But that’s how a PD compliant charger should work, no? Most Anker ones are, so I’m confused by the reported issues people are having. If use the output capable of greater than 18W, it will still charge and not brick the system because it charges accordingly.

I do not understand why you don’t just continue to use the charger(s) you have that work with your Ace and be done with it… it seems pointless arguing over the Sonos Staff members post - saying minimum 15W etc. it might even be an unintentional error in their post anyway. Personally I always thought it was 15W (5V x 3A) that was being used in anycase, same as the Roam, as I can’t see the Ace needing the higher power input used by the larger Sonos Move battery - which apparently is as follows (taken from other community posts)…

The power adapter for the Move/Move 2 must be USB PD (Power Delivery). For 45W operation the PD source must put out either 20V/2.25A (or higher current) or 15V/3A (or higher current).
For 36W operation the PD source must put out 12V/3A or 15V/2.4A and note that charging speed is reduced if listening to audio at the same time. Anything less than 36W will not power or charge Move.

So 15W seems about right to me as a minimum, because some chargers might output 5.2V x 3A (15.6W) perhaps and may still work - I wouldn’t like to test it however and will stick with PD chargers, personally speaking.

Yes, that's what I thought too. But after reading some USB documentation, the receiving device must be able to regulate it too, not just the charger brick.
