I used to have noisy neighbors who would party until very late at night with loud music. In addition, my apartment only had one room towards a big road.
Often, I couldn't sleep until 2 or 3 AM when parties ended and would be waking up around 6 or 7. Ear plugs didn't help since the sounds were too loud.
This lead to me constantly being tired and overall made everything else in my life more difficult. I lived like this for years.
Then, one day I saw an ear protection gear (the type that construction workers normally use) in a store for only $5. I decided to buy it, thinking that it might help me relax but that I wouldn't be able to fall asleep with them.
Well, it turned out that I was able to sleep with it and I started to consistently get 6 or 7 hours of sleep. Best purchase of my life.
TLDR Lived in a very noise environment and couldn't sleep. Bought an ear protection gear for $5 dollars and slept like an angel.
Yup. They aren't that big but definitely uncomfortable for your neck. But the slight neck pain is totally worth it.
