Earphones
Or
Headphones

I usually use earphones because it's easier to bring along. It's also easier to hide than earphones if those stuff aren't allowed in your school (it's ok in mine, as long as we don't use it in class). Another reason is... I don't own any headphones. 😢😅

BTW, belated happy birthday to jkt101 !!! I forgot to give her a birthday present yesterday, so she requested me to give her a shout out in one of my books as a gift.

I'm sorry that I forgot to give you a gift! I didn't forget about your birthday, though. I have a collage for you too! ('Cause a shout out and a rushed drawing isn't enough for your awesomeness)
