I have this problem with Airpods Pro, Sony XM4 and most notable, the Devialet Geminis.
With ANC on. and when chewing, I get this driver flex like noise especially in the left ear. Pops, crackle, some static sounding interference (APPs)
For instance the Geminis are unusable with ANC HIGH ON and with silicone tips. I would say the XM4's are in the same category.
Now I have to use Comply Foam (TW-200-C) on both the Sony and Devialet. The Devialets I also have to use ANC LOW.
The APPs just give this static noise, and a kind of distortion when chewing and also when taking a call.

There's no noise at all when ANC is off with either of the TWSs!

With my pinky finger in the left ear, I feel that the jawbones affect the ear canal a lot in the left ear when chewing/opening mouth. (sorry I couldn't explain it better)
I guess this is the reason? The mics are picking up the movements and I get this noise with ANC on??
I suggest that not only are the mics potentially picking up movement sounds, but that the earphones are adjusting to changes in air pressure from chewing, resulting in some noises.
All that said, not to state what you may already know, but wrt to APP, apple has a repair program for older APP that have noises such as you are describing.

https://support.apple.com/airpods-pro-service-program-sound-issues


An affected AirPods Pro may exhibit one or more of the following behaviors:
  • Crackling or static sounds that increase in loud environments, with exercise or while talking on the phone
  • Active Noise Cancellation not working as expected, such as a loss of bass sound, or an increase in background sounds, such as street or airplane noise

Thanks.
Yes, I guess you're right about the air pressure change. Most likely what's causing it.
When using smaller tips, and not getting a good seal (Gemini medium silicone tips for example), this problem is almost non excisting.

I know about the Apple service program. Mine is produced January 2021, and are not affected by this. I have no other problems with them, other than some noise when chewing/talking (moving mouth) and with ANC on as well.

Not sure i follow your point re aptX adaptive. I know Samsung and Apple dont have it but newer Qualcomm based phones seem to. Maybe i just think that because both my LG V60 and OnePlus 8T have it. AptX adaptive is also supposedly backwatds compatible with other aptX codecs like aptX HD (e.g. if you use the PI7 with a device that has aptX HD but not aptX adaptive your phone will send to the PI7 via aptX HD). However, if the phone is capable of aptX adaptive, you get aptX adaptive and not aptX HD (at least I have not figured out how to force aptX HD instead). I think we will continue to see more aptX adaptive devices until we get Qualcomm's new Lossless codec, which I understand may be based on aptX adaptive.

Maybe I misunderstood your comment.
You understood me. I was complaining mostly about Samsung who doesn't support either Adaptive or HD. Given Samsung sells like 5 out of 10 Android phones worldwide, it seems like Adaptive isn't really that prevalent. I do understand that other Android makers support it. As far as backwards compatibility, I'll see if that is right. I have a pixel that supports Aptx HD so I'll see if I can force Aptx HD on them. That would be cool and come to think of it, my PI7 does this as well.

You only get aptX HD if the earbuds add it separately, aptX Adaptive falls back to aptX if you do not have support for it on your phone.

I like you had a set of B&W P14's (aptx Adaptive) on my Moto Z2 Force and they have the separate aptx HD codec so that is good for me but all others since using the QC3040 do not so you loose HD.

Argh bummer. So bizarre that they would go with Adaptive but not HD. Now, I do have the creative USB Dongle that supports AptxHD and can convert a phone to an AptxHD source. So if I combine that with the headphones that support Aptx Adaptive perhaps that will work.

FYI that is direct info from Lenovo/Moto staff as I was pissed about it and posted on their forums and it was due to QUALCOMM's confusing info and he had to get back to me on it after asking the engineers if it can be added but the chipset in my phone does not support it.

Your second part is the same situation as mine, my phone does support aptX HD but not aptX Adaptive so no it will never only ever be aptX if your using aptX Adaptive earbuds unless like above they added the addition aptX HD codec like B&W did on the P14's.

I also tried it with 2 USB adapters that support aptX HD and it falls back to aptX.

It's truly bizarre on all levels. All of these codecs are supported in the base android OS so the fact that manufactures are enabling some and not others is really a detriment to consumers. Samsung appears to be disabling HD and Adaptive in favor of their own proprietary codec.

I was told the phones chipset has to support aptX Adaptive (enabling it in DEV does nothing) like your phone chipset had to support TWS+ or the TWS+ buds fell back to TWS (Master/Slave Mode) but now we have aptX Mirroring so the phones chipset does not matter as it is done on the earbuds.

I’ve finally gone and gotten myself a pair of Devialet Geminis!

I realized that the included tips are less than great at least for my ears, I realized that when I tried so hard at liking them but felt like I was less than convinced.

What made me realize that they didn’t fit well was that changing the EQ in the app barely changed the sound at all, but then I switched to another set of tips that I have and now the EQ-ing actually makes a difference and can be noticed even if you switch a slider just one step up or down, lol.

im still not convinced that I think these sound better than the MTW2’s to my ears but I’m still getting used to them so I might just change my mind about that later on!

Samsung definitely is and has been for a while. This is why I stopped buying Samsung phones once I started getting into bluetooth. Owned every Galaxy phone from GS3 to GS9 and a Note in between too. Wife still uses the Flip 3 though because she, like most consumers, doesn't care about codecs.

Anyway, once you get your cans, please lef us know what it connects using. I am very curious. I was actually very unhappy that the PI7s did not connect to my Node 2i via aptX HD, which definitely has aptX HD (works fine with other devices like my Aonic 50, ES100 and Qudelix 5K).

So good news, these connected right to AptxHD on my Pixel despite the fact that the Yamaha literature only lists Aptx Adaptive. As an aside, for anyone looking at cans, these things are pretty cool. The 3D DSP is very effective - similar to the Mobius with multiple DSP Modes and head tracking. I still haven't figured out why I need head tracking or whether I like it but I do like the DSP. It adds some space to stereo music listening and it seems just as effective as spatial audio but without the proprietary nonsense. There is an "Audio Room" setting I really like; I may have a hard time going back to regular 2D stereo after this. Like a lot of ANC headphones, these have a lot of bass - in ways that you can't get out of TWS and which is much thicker than I am used to with my open and closed back planars. I'd love to compare these to the H95 for craps and giggles.

Samsung are scum, all their bluetooth buds have the Samsung Scalable codec, so basically if you want good quality bluetooth Audio with a samsung phone, you need Samsung buds to get it, every day they go more in to apple terretory. the only other company that does this is Huawei, The freebuds pro use the Huawei scalable codec and AAC with non huawei devices.

If Samsung is scum then what is Apple?

That is the same way the PI7 behaves. I think it is backward compatible but the implementation is inconsistent and there are some compatibility issues (such as the issues I had with my Node 2i and PI7s). Glad it worked for you. Actually thinking of grabbing a Pixel next I think since it has aptX HD dual SIM (another thing Samsung cripples in the US), and all the 5G bands I need.
