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.

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.

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.

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.

The PD chargers ‘actual’ power output ability for each port is usually stated on the charger and if it has multiple USB ports, it will usually state the changes if either two, three etc. ports are being used simultaneously.

When I purchased my PD chargers around 2020/21 - I was only able to get a 100W PD charger, but these days they can go upto 240W power output, but will still only charge my Roam-2 at 5V x 3A (15W) for example (and Ace too at that level). I use E-marker chipped power cables too, as that helps to ensure that only the correct ‘negotiated’ power is used to charge a connected device.

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.

That’s pretty wild. IIRC there’s been issues with Move and Roam with chargers as well. I wonder what it is with Sonos?

that makes sense, but I didn’t realize it. I’m hoping no issues pop up for my pair, have been trying to test and charge to see if they end up being bricked or not charging.

Look at the various power outputs available printed on the PD charger itself. It needs a usb-C (not usb-A) port, with a power output available of 15W (5volts x 3amps) - if it says that on your charger block, then you should be okay.

Note that with chargers that have two or more ports, you may find that some outputs may become unavailable when more than one port is being used simultaneously, but that information should be printed on the charger aswell.

Basically, just read my summary again a few posts up, without the superfluous subsequent reply.

18W or lower. Old USB-A chargers do work because they're 18W or lower. Higher wattage chargers (like Apple's 140W) can work as long as it can output 18W or lower.

Some PD 3.0 certified chargers (even though equipped with PPS) can't go lower than 20W because it's 2024. But apparently Sonos Ace as the receiving device can't even regulate that. So be careful. 18W or lower, and you'll be ok.

USB-A is no longer part of the current PD certification - but yes they can work but I recommend using the later USB-C with a power output stated on the the charger itself of 5V x 3A = 15W and (hopefully) all being well it should work with the Ace - yes I accept other chargers/output may work but that output is the common denominator on all the PD chargers here that do definitely work.

Ken_Griffiths

Please note too @darksage94, the overall wattage available for the charger is irrelevant, it’s the various power-outputs of each USB-C port that’s the important factor here - some PD chargers that are 100W or even 240W will still be able to show a power output of 5V x 3A -15W - the various available power outputs for each of its ports will be printed on the charger itself.

Ken_Griffiths

This 100W charger, just as an example, has two USB-C ports that can output at various voltages in compliance with the PD standard - I have highlighted that one or both of its ports can output 5V x 3A which is 15W - see image below. So both of its ports will charge the Ace or even two Ace headphones simultaneously.

Ken_Griffiths

The exact same charger will also charge two Sonos Move/Move 2 speakers which each require 45W power output 15V x 3A = 45W. See here:

So it’s important to look at the power output available for each USB-C port and it should be printed somewhere on the charger.

It's embarrassing how a new pair of headphones in 2024 that costs 449 USD to buy can't regulate the charge that comes in from PD chargers. While much older devices from almost 10 whole years ago can.

Sonos Ace along with the new app (which was updated to accommodate the Ace) have been far far away from a good look for Sonos. Extremely disappointing.
