second-hand-transactions simple-change-of-heart refund

I sold earphones for second-hand transactions.

A few days later, they said they didn't like it and asked for a refund.

Do I need to get a refund for a simple change of mind in a used transaction?

You don't have to do it, right?

There's no problem if you don't do it

It's very vague on second-hand transactions.
It's a personal transaction.
If you do that, the other person will thank you
If you don't do it, you'll feel comfortable.
I'll just do as I want.

I think it's right not to do it after a few days.
It's not like it's not working.
