Some people like to [[id:2022-01-25-mood-environments][have a certain sound environment]] when being
productive, traveling or sleeping.

For people who do prefer silence instead, you can get active
[[https://en.wikipedia.org/wiki/Noise-cancelling_headphones][noise-cancelling headphones]] (ANC). But be aware: really good ones come
with a high price tag with probably at least 250€.

I was able to test Bose QuietComfort QC-15. They do seem to be very
good at canceling noise but I didn't like the slight pressure in my
ears. Most people do not seem to care about that. Furthermore, some
models do require the mandatory built-in battery also when you do not
use the ANC feature.

For getting a similar result I can recommend [[https://en.wikipedia.org/wiki/Ear_protection][cheap ear protection
equipment]]. I do have a 3M Peltor Optime III 3-layer ear caps for about
20€. I used this protection when I needed to concentrate while working
in a room with other people doing phone calls or similar.

When traveling, I prefer foldable ear protectors from Howard Leight
(around 20€) together with optional normal in-ear headphones
(meanwhile Bluetooth-driven) which you most probably do have already.
This combination needs no extra batteries, is cheaper, more flexible
and offers better results than most ANC headphones in my opinion.

This way, you can get the same result as really good ANC headphones
but for a fraction of the cost.

In case I do need to get rid of noise while sleeping, I prefer very
cheap in-ear-plugs. I can not stand anything on my ears while sleeping.
