I recommend my own sleep item, 3M earplugs.

I am sensitive to even small noises and have trouble sleeping. Once I fall asleep, it's okay, but the problem is falling asleep. The sound of my family talking in the living room or even a little TV noise makes it hard for me to fall asleep. That's why I always use 3M earplugs. Once inserted, they block out 80-90% of external noise. So, I don't pay any attention to the noise from the living room. If noise bothers you while sleeping, I recommend 3M earplugs.
