I think the expected answer is that you use headphones and earphones for different situations.

I use headphones in the studio for better sound and longer sessions.

Earphones usually on the go because they are easier to pack and I can wear glasses/sunglasses if needed. It's easier to take out one earbud if you need to listen or talk to someone.

In both cases, I like to use cables rather than wireless, but they do get tangled on everything.
