Completely off topic, but when did people start calling earphones “headphones”?
Headphones are the cans that cup your ears and strap around or over the head. Hence their name.
Whereas earphones go inside your ear.

Re: The AirPods Pro 3 flight problem
#92A wild guess as to what is happening. I haven’t actually tested this hypothesis so I could be completely wrong. In feedback systems, the gain is a function of frequency, and typically decreases when going from low frequency to high frequency. This is often accompanied by a phase delay. So if the overall gain of the system is high enough, there will be some high frequency where the gain is 1, and the phase is 180 degr…
Sounds like you are stating https://en.wikipedia.org/wiki/Barkhausen_stability_criterion (1921): "if A is the gain of the amplifying element in the circuit and β(jω) is the transfer function of the feedback path, so βA is the loop gain around the feedback loop of the circuit, the circuit will sustain steady-state oscillations only at frequencies for which: 1: The loop gain is equal to unity in absolute magnitude, tha…
But you said "phase is 180 degrees" which is 1π, while Barkhausen instead says integer multiple of 2π.

#93Interesting. I have roughly 50,000 flight miles on the new AirPods Pro 3, and while I do prefer them to the 2s, I too have some annoyances with the left AirPod. In my case it never feels like it fits my ear canal quite right, to the point that I thought I might want different size tips - after trying all the tips, that's not it. The seal is in fact good, but the different feel is noticeable. The noise cancellation al…
Wow you fly a lot! These things are out what, 2 months? :O
Doesn't that get exhausting? I used to have a job where I'd be on a plane every week and I couldn't hack it. It's supposed to be liberating to travel but basically just seeing the inside of a plane, taxi, meeting room and hotel room every day it was more like a moving prison. Sometimes I'd sneak out to walk through these strange places. But often I'd be forced to attend boring business dinners.
My last business flight was in 2018 and I don't miss it at all :) I even cancelled my corporate amex since I never use it anymore. And these guys keep asking for copies of ID and stuff for tax records or something (completely stupid because yes I'm still the same person duhhh) so in the end I just rolled my eyes and told them to stuff it where the sun don't shine :P

I'm not sure if this is a "when did people start" situation. I have never heard a layman use "earphones" in casual conversation.
Re: The AirPods Pro 3 flight problem
#95Something interesting occurs to me. Many of the anecdotes about the squealing on flights says the noise goes away when yawning. Yawning lifts the soft palate and equalizes ambient pressure behind the eardrum in the sinuses. Air pressure is lower in a pressurized airplane cabin than on the ground and is usually more dynamic as well. I wonder if an air pressure gradient forms in the ear canal when in the air that exacerbates the ANC feedback issues that users (myself included) are experiencing on the ground. I feel like there must be some interaction between the multiple microphones due to vibration transmitted through the body of the Airpods.
Since it seems to be an ANC issue it should be fixable in software.

I'm reasonably certain that I am about as old if not slightly older than the invention of in-ear headphones. I'm also reasonably certain that I have always used "headphones" to refer to any small portable speaker designed to inject sound directly into the ears. I'm absolutely certain I have never used the term "earphones", although "ear buds" was/is a common synonym for in-ear headphones.

People definitely used to. Or at least in the UK they did.

I’m probably around 2 decades older than the invention of earphones and people definitely did used to call them that here in the UK.

Yeah, might be a UK thing. In Canada/the US I've only ever heard "headphones" and "earbuds" (a specific kind of headphone).

Another example of us being separated by a common language. I don't think this has ever been common in the US.
