I use wireless earbuds most of the time. They're easy to carry and I don't have to worry about wires getting tangled. I use them when I go to the gym or take the subway.

I like over-ear headphones because the sound is better and they block out noise. They're comfortable when I study at home or want to focus.

I use wired earphones because they're cheap and I don't have to charge them. If I lose them, it's easy to buy new ones.

Actually, I don't use headphones very much. I prefer listening to music out loud, except when I travel or need some privacy.
