Airpods Pro 3 - low frequency sound leak in noise cancellation mode

Hey Team,


I've been using the new AirPods Pro 3 for some days now (model number A3063) and everything has been good and smooth up until now. As of today, when I put the headphones in "Noise Cancellation" mode and I am in a cafe where there is background music playing, all of a sudden the noise cancelling doesn't "cancel" the low frequencies anymore. Furthermore, I get the feeling that the low frequencies are even "enhanced" as if the headphones are adding additional bass to the "outside" music. The sound level of the outside music is pretty low (more like background music) so we are definitely not talking about loud sound source being blasted into the headphones.


This behaviour is sporadic, so if I try putting the headphones back in the case and then back on, sometimes the issue disappears and the outside low frequencies are blocked just fine. I've tried switching between modes when the issue is present, however this doesn't change anything. I am also using the headphones in Noise Cancellation mode, not Adaptive, and I got all Adaptive Audio, Personalised Volume and Conversation Awareness turned off. I've also tried changing tips, but that's not it either.


The AirPods Pro 3 are running the latest 8A357 firmware and I am running iOS 26.0 on an iPhone 16 Pro.

Does this sound like a software bug or could it also be hardware related? Any advice would be much appreciated.


Thank you in advance!

After heavy testing on my side, it seems to be fixed for me in 98% of the time.

My initial post is this: Airpods Pro 3 - low frequency sound leak … - Apple Community

But as stated: I got replacement buds from another factory, which still had the issues, BUT new firmware helped.


On 8B34 in public transport I had ZERO low frequency leaks (surface level, underground trains, cars, taxi) WHEN the airpods were properly set in the ear and sealed good.


If you wear a hat or beanie or such thing, and on airpod slips just a little bit, resulting in not properly sealing THAN I have VERY little low frequency leak.

But if they were in correctly it was fine for me.

In the office they worked as intended, only if you remove them on by one and put them back in the ANC seems to get "confused".

popping them in case and back on fixed it every time.


Even at home with a big 3d printer besides me in homeoffice or my portafilter for espresso (lelit bianca v3) or my espresso mill (eureka mignon libra) which all produce a lot of deep rumble, were filtered perfectly.


I hope it stays that way or even gets improved.

I have this exact problem. It’s only on my right airpod and sounds like a low bass hum. Kind of like you are putting a cup over your ear. At first I tried to ignore it but now I can make it out even when listening to my music at a higher volume to try and cover it up. I was hoping the new firmware update would fix it but I'm currently at the gym after updating them and hear it right now.

I have also been facing the same problem. Also from around 3 days after purchase. Received on launch day and soon after this low freq leakage began. Seems to only happen when music is playing with ANC on. Turning off all of the relevant settings like convo awareness and hearing protection changes nothing. Still leaking low freq noise. Newest firmware 8a358 didnt fix it either.

I thought this was fixed but is still not. If anything it seems to happen more now. Not sure if caused by firmware update or because of the larger ear tips I’m trying. With the size large now it happens all the time but before with size medium it was a bit less frequent. Rules out a bad seal I guess. I have to reinsert my AirPods every couple of minutes to retrigger the anc to work as it should. Basically unusable.

I replaced my AirPods again a week ago, on January 29, hoping it was some hardware issue. The problem is still there. 8B34 does not solve it. That probably means it’s a hardware or some core issue Apple is ignoring or can’t solve. It is so annoying because ANC is the main reason I use the Pro series, and I replaced the Pro 2 with the Pro 3. How can you base the whole product's advertising on a feature that doesn't work correctly? If I knew that, I would never replace Pro 2 with Pro 3. I have been a fan of the series since its launch. Now, I literally hate it. Extremely disappointed.

我在在安静的房间使用时会听到室友的呼噜声是通过低频传到耳朵里的还有窗外车辆经过的轰隆声也会传到耳朵,尤其是在车间里面机器运转发出的声音传到耳机里尤为明显非常烘耳,声音像是啸叫声还有空调运行的的声音,在安静的房间内左耳有电流声,非常困扰,我去线下检测没有硬件问题使用过程中就有问题,我已经从固件8A358更新到8B25还是有这些问题,重置会变好,下次佩戴会再次出现。
