Its often underestimated how much noise can affect our behavior and health. During long flights the constant noise makes you tired. Therefore I use hearing protection from @earwear.me
It’s individually customized and fits perfectly. It blocks the static noise but let’s you understand human voices.
If you care - you better wear.
Do you use hearing protection in loud environments?
Or if the your boss starts yelling at you, you better put those things in ;)
