Then again... won't that summed audio source be at the mercy of my loud speakers?
If you mean by that that it couldn't be louder than what the speaker could produce: No, because you're adding to the original noise entering your ear from the outside.

I'm personally a fan of the conspiracy theory that because multiple ANC products have had their abilities reduced in firmware updates over the past couple years, research teams have been independently finding out that user's hearing are being damaged by highly effective ANC and have had to turn them down without admitting fault. Although I'm not even sure if that's how sound waves work, and recently there was Bose's…
The other option is that Bose, Sony or some other high-end audio company has a patent on whatever noise cancellation system was in place originally. A decision was made to avoid a legal battle (or a deal fell through at the last minute) and the feature was nerfed until Apple can strong arm the patent holder into a better deal.
Couldn’t Apple or Bose just fall back on these methods which should work closely enough to whatever fancy method is patented? Or is the method I’m describing patented?
It's not about pressure as having something tucked into your ears, but related to the noise cancelling: "You may notice a pressure-like feeling in your ears when you first put noise-cancelling headphones on, like when you want to 'pop' your ears. This is caused by your brain perceiving the lack of low low-frequency sound as a pressure differential between your inner and outer ear, just like when you ascend in an airplane." If you search for Airpods and pressure, there are also comments on Reddit etc. I did not investigate if those are referring to this phenomenon.
Something like this could explain why Apple would like to tweak with the noise cancelling.

Why would you bike wearing noise-cancelling headphones? It seems odd if one values one's life.
They have a hear through option that works with wind noise, unlike a lot of other ones?
One firmware update has even rendered one of my AirPods Pro practically unusable due to a strange clicking noise that would occur whenever I was walking/running with ANC enabled, likely due to accelerations acting upon it. I was convinced it was a hardware fault and was ready to return them until another firmware update fixed the problem (until now at least).

> Isn’t ANC effectively twice the sound waves? ideally no, just the opposite. the idea of ANC is that you detect the frequency and amplitude of incoming waves, then generate a second wave with the same amplitude, but 180 degrees out of phase (so that the trough of the second wave aligns with the peak of the first). a perfect implementation would totally "cancel" the original sound with destructive interference. I'm n…
Yes but perfect destructive interference isn’t possible unless everything remains fixed in place which is difficult on a living human head. Its quite possible to get temporary constructive interference for short periods, and also plausible the brain would filter the spurious noise out.
I am just absolutely fed up of the battery situation. By the time the devices are broken in and you are comfortable, it's time to buy another pair. I am not that rich.

That's my theory! I bought the airpods pro before nov, and around nov 2019 I developed tinnitus that I couldn't pinpoint the cause of, even after going to an ENT & Audiologists. After going to the Audiologist. I also found out tinitus is a big mystery in the medical field outside of a small band of causes that I didn't have. The only difference in my day to day was the Airpods Pro and biking to work with them.
