noise cancellation devices

it's a rabbit hole 😬
but let's start with earplugs: why not an option?

You need to get used to earplugs. You can try the cheap 3M 1100 (-32db nr).
They are soft and more comfortable than any other in-ear device.

however over-sensitive to sleeping conditions at the same time :(

You can’t sleep well in a noisy environment.
Unless you sleep on your back and you don’t move, over the ears active noise reduction headphones are not an option, and anyway they are less comfortable than earplugs for prolonged wear.

You could create your own cocoon around your head using sound absorbing panels, but it would not be as effective as earplugs and you will suffer from heat.

In your own room or airplane you can create an active sound reduction system oriented towards the bed. There are some companies that can custom make it, for 5 figures (or 6 in an airplane). Obviously this can’t be done outside of your property.

Some people find relief from white noise (rain, waves etc). It can be used for short periods of time if it works for you.

The last resort is to sleep elsewhere. Sometimes you can find more silence in the bathroom, in which case move the mattresss there.

I know about white noise producing devices but have no experience and I'm afraid that it's just another gadget that will end up unused... hence the question whether somebody uses anything like that

True white noise is annoying, it's basically the hiss from old cathodic TVs with flickering b/w screen.
Sounds from nature are more bearable and often more usable.
No need to buy a dedicated device, just use a decent speaker connected to a youtube video:

White noise
Waves
Rain

Did you try a headband with some extra padding over the ears?

Try a soundproof sleep tent like this one: a.co/d/eJlKB8O
Or a smaller version just for the head:

Try reducing stimulants, no smoking (of any kind), no nicotine, less internet, eating healthier, reading a book.

Unfortunately all this doesn’t help with noise

It helps me though. The stimulants are stressing your brain, therefore you become more susceptible to noise.

Lucky you if noise doesn’t disturb you when you are relaxed!
I can be as chill as I can but if the bitch upstairs decides to wear high heels and dance at 4am I will wake up no matter what.
In some luxury hotels walls are so thin that you can hear whispers from the next room. And the always present trolley roaming in the corridor at nonsense hours.

This would be a dream, if only someone could mass produce it

Headphones are not fully safe nowadays.

Any device near to the brain can cause a serious issue.
