There's a huge runway in front of us for both products and technology.
'Acoustic Holography' has worked for some time, commercial implementations have been few and far between, mostly because what's in the market is already selling boatloads without it.
It'll come eventually, there are a few groups dedicated to it.
A successful anchor in that space will allow companies to go deeper into applications.
Acoustic room splitting, Silence on demand, etc.

Recently I started a job that has me using a headset with ANC (active noise cancellation). It was OK for the first week or two but then I noticed my head hurt. My ears felt full and I had ringing in my ears that was quite loud. I have mild (self-diagnosed) tinnitus but this was beyond that by a significant amount. I'm aware of how noise cancelling technology works it's by creating an opposing sound wave of equivalent…
Try IEM's.

>wearing active noise canceling headphones for extended periods of time can be uncomfortable and even cause injury Does anyone know what type(s) of injury is this referring to, how long is too long and how widespread/likely it is?
I wear Sennheiser HD1 M2's (with ANC) for ~8h/day, 5d/week, and have been for over 2 years -- with no discomfort or unwanted side- or after-effects. Ofc I'm careful about volume level, and I take frequent breaks from both screen and headphones (albeit for the sake of my eyes). I'm a healthy 47yo software architect by trade, also a lifelong musician and music afficionado. I care about -- and for! -- my ears and hearing, and would be grateful for any good links to credible sources (ie peer-reviewed scientific studies) which highlight hidden dangers or damage.

I am assuming this is a fairly common feature for headphones? If so you might be able to switch models to one that has an off mode, if yours don’t.

I don’t think this is even possible. Noise canceling works by creating reverse waves that hit your ears at the same time. You have to be able to calculate how long it will take for those waves to hit each set of ears and be able to direct sound at them.
That's the simple, signal-processing oriented way to noise cancellation. But what if the software/ai is advanced enough to reproduce a sound, but erase a certain aspect of it? Like how photo editing can edit out an object or background? Then the headphones can use a seal to completely block out all noise, and play only the sounds the user selects!
The problem is you can’t possibly work out exactly how and when the sound will hit each set of ears around you to be able to direct a beam of sound to their ears (assuming it’s even possible to have such directional sound)
The problem is significantly easier with headphones. You have a headphone and speaker in between your ears and the sound. The distance between the microphone and your ears is constant so you can perfectly time the negative sounds.

If we could make a seal that blocks out all noise small (and confortable) enough to fit around a headset, we wouldn't need the whole NC setup. Earplugs below my bose headset work wonder to block out anything short of cataclysmic, but it's hardly practical. And I can't exactly play music with those on...
