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!

Yesterday I installed 26.1 PB2 hoping for the yet unreleased AirPods firmware but it hasn’t yet installed. However, I’ve been using them all day today in the office where this issue would manifest regularly with and repeatable and so far I haven’t encountered it. Despite the AirPods being on the 8A358 firmware as they were before. Weird. Maybe coincidence or maybe it was iOS forcing them to screw up.

My new AirPods Pro 3 were flawless for the first three days, but then things went downhill. On a long train ride, I noticed the left bud suddenly started leaking sound out of nowhere.


Every time I take it out and pop it back in, the issue disappears for about two minutes. Just as I start thinking it’s fine, the low drone creeps back in.


I tried a hard reset, which fixed it for about two days. But earlier today, I noticed the ANC performance slowly declining again. It was manageable at first, but just a few minutes before writing this, the rumble became way too distracting.


For context, the issues resurfaced while I was on a train this afternoon. Now I’m on another (longer) ride, and about 20 minutes in, the problem flared up again. It really seems like prolonged exposure to low frequencies trips up the software somehow.


The funny part? Now it’s the right bud acting up while the left one has gone back to normal. 😂


Really hoping a firmware update drops soon, because this is getting pretty annoying. Haha.

I'm having the exact same issue. Feels like it is leaking in/amplifying low frequency sounds, such as bassy music in a cafe, noise in public transportation, vehicle engine noises from a crowded road etc.


Mostly happens in my right bud only.


My airpods are running firmware 8A358, and the device paired to the airpods doesn't seem to be a factor as the issue presents itself when paired to any of my iphone/ipad/mac, running beta/non-beta software.


Putting the airpods in the case for around 30 seconds doesn't seem to fix this. Resetting the airpods only temporarily fixes the issue.

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.
