Eli5: why do wired headphones that plug into your phone never need to be charged but wireless ones do?

Question

I thought maybe they got power from the phone but then I remembered old headphones plugged into a phone jack separate from the charging port so how come one type never needs to be charged and one does?

The technology behind wired and wireless headphones is very different. Wired headphones use a cable to connect to your phone, which uses very little power. Wireless headphones use Bluetooth, which uses more power and therefore needs to be charged more often.
