I wear earplugs when commuting in the bus. I take a city bus that drives 80 km/h on the highway and the noise is deafening. If you'd work in that environment, ear protection would be mandatory.
I can't imagine how awful it feels to wear cheap earbud headphones in that noise, yet most passengers do.
Is your environment noisy, or does this help you even in a quiet room?
It's not especially noisy, but it helps me sleep anywhere. It's a godsend in hotels. I don't know why I never considered them before.
