What connections does the Huawei P 20 Pro have?

There are some holes at the top left and right what kind of holes are they
and there's a simple adapter without a cable where I can connect analog Marshall headphones

Micros for ambient noise, above that the noise suppression works.

What kind of adapter without a cable are you imagining, and without knowing what kind of headphones you have, nobody can help you, analog doesn't mean anything at all.

Hello up there's a big and a small hole I have a Marshall in-ear headphone but there's no headphone connection, what do I need for an adapter, something that can be plugged into the chinch plug

You need the adapter for this
