Hi! Recently picked up the sonos ace and I’ve noticed some flaws….
A really cool feature of the sonos ace ANC is how it turns off in low noise environments to reduce white noise. This is a great feature I think because I hate the white noise. However when the ANC kicks in, it sometimes makes a “pop” sound that can get a bit annoying. Is this normal for the headset? I notice it the most when I’m on my PC clicking the mouse, 

Also I’ve noticed a fair amount of clicking/poping sounds when moving around, the noises come from the hinge system as when I press on the headband the noises disappear. Very noticeable when running on a thread mil. Is this normal too?

Both these issues are identical on both ears, which makes me think that it’s normal, just want to check if others have experienced the same :)
Thanks for reading.

Hi ​@Rawrvik 

Welcome to the Sonos Community!

Sorry to hear you are not entirely happy with your Ace headphones.

A really cool feature of the sonos ace ANC is how it turns off in low noise environments to reduce white noise. This is a great feature I think because I hate the white noise. However when the ANC kicks in, it sometimes makes a “pop” sound that can get a bit annoying. Is this normal for the headset? I notice it the most when I’m on my PC clicking the mouse, 

I am not aware of Ace turning ANC off by itself. ANC is either on or off depending on the mode you place it in using either the Sonos App or the button on the headphones.

I recommend you ensure that your Ace is up-to-date: to go through the update process, your Sonos Ace must be set up in the Sonos app and connected to your iOS or Android device via Bluetooth.

  1. Open the Sonos app for iOS or Android.
  2. Navigate to the Settings menu and select your Sonos Ace under the Headphones section.
  3. Under About, select Software Updates.
  4. Select Check for Updates.

Also I’ve noticed a fair amount of clicking/poping sounds when moving around, the noises come from the hinge system as when I press on the headband the noises disappear. Very noticeable when running on a thread mil. Is this normal too?

I would say this is probably normal for anything consisting of multiple materials joined together that is extremely close to your ears, though I also have to say that I would not use Ace headphones on a treadmill. I use a treadmill daily and would not wear headphones or earphones while sweating - I don’t think it’s a healthy thing to do, but that may just be me. I have a Roam nearby.

Both these issues are identical on both ears, which makes me think that it’s normal, just want to check if others have experienced the same :)

Hopefully, a software update will sort out the first problem for you, though I confess I don’t entirely understand what you meant there. I have my own set of Ace headphones and have not noticed these points you have mentioned.

I hope this helps.


I've also experienced the same popping noise on my Ace, particularly a loud pop when I turn off the unit. Initially I returned one Ace under warranty for that reason and received a new unit. That new unit worked fine for about 2 months then the popping sound has returned. Happens about 25% of the time when I turn off the unit. Pretty annoying/concerning since it's such a loud pop, but I'm under the impression it's pretty prevalent.


I’m not observing this “pop”.


Hi ​@koala5262 

I am sorry to hear that - I can only suggest that you get back in touch with the support team and quote your previous case number, letting the agent know that you now experience the same issue with your replacement Ace headphones (but did not initially).

I hope they are able to help.


I just bought my ace last week. Instantly noticed the “popping / crackling sound” worked with support and ended up having to send back as they were defective. The volume on mine while at 100% seemed like 60% max and no bass to speak of. So I’m waiting now for my new pair in the mail. But the next day I realized the popping sound that originated from the ace was now happening to my left rear era 100 spoke to customer service back and forth trying every fix and after at least 10 hours of time spent dealing with customer support they finally arrived at the conclusion that the era 100 it self was now defective. They are sending me a replacement. The whole thing has been a nightmare. What should have been pure excitement and joy from my new headphones turned into hours of my time on the phone and having to swap multiple devices and I still don’t have my headphones going on a week now. I will say that at least Sonos realized it was Sonos issue and was willing to make me whole even though it took hours of my life I’ll never get back to do.
