Is it possible to hear sounds through headphones on your head?

Yes, it is possible to hear sounds through headphones while they are on your head, especially if the headphones are not sealed or are open-back designs. External sounds can leak in, and some sound waves may travel through your skull, allowing you to perceive sounds even when wearing headphones. Additionally, if the volume is low or if there's significant ambient noise, you might still hear sounds from your environment.
