에서 marks the place where an action happens. In this sentence, it means the action of wearing headphones and listening to music happens on/in the subway.

• 지하철에서 = in/on the subway
• With action verbs, Korean often uses 에서 for the location of the action.

Compare:

• 학교에서 공부해요 = I study at school
• 집에서 쉬어요 = I rest at home

If you used 에 instead, it would usually sound more like a destination or location of existence, not the place where an action is actively being done.

끼고 comes from the verb 끼다, which means to put on / wear certain items.

It is used for things you wear on or attach to a part of your body, especially things like:

• 안경을 끼다 = to wear glasses
• 반지를 끼다 = to wear a ring
• 이어폰을 끼다 = to wear earphones
• 헤드폰을 끼다 = to wear headphones

So 헤드폰을 끼고 means wearing headphones or putting on headphones and...

Here, -고 connects it to the next action.

Korean uses different wearing verbs depending on the item.

• 쓰다 is used for things worn on the head, like hats
  
  • 모자를 써요 = I wear a hat
• 끼다 is used for things you put into/on part of the body, such as glasses, rings, earphones, or headphones
  
  • 안경을 껴요 = I wear glasses
  • 헤드폰을 껴요 = I wear headphones
• 입다 is for clothes
• 신다 is for shoes/socks
• 차다 is for watches, belts, etc.

So 헤드폰 normally goes with 끼다, not 쓰다.

Because both are direct objects of verbs.

• 헤드폰을 끼고
  
  • 헤드폰을 is the object of 끼다
• 음악을 들어요
  
  • 음악을 is the object of 듣다 (to listen to)

So the sentence contains two verbs, and each verb has its own object:

• wear headphones
• listen to music

That is why you see 을 twice.

-고 connects verbs, often meaning and.

So:

• 헤드폰을 끼고 음악을 들어요 = I wear headphones and listen to music = more naturally, I listen to music wearing headphones

In many cases, -고 simply links two actions done by the same subject.

It can sometimes imply:

• action 1 and then action 2, or
• action 1 while action 2 is happening

Here, it most naturally suggests the actions are closely connected and effectively happening together.

It can be understood either way depending on context, but here it is most naturally interpreted as simultaneous or closely connected.

So the idea is:

• the person has headphones on
• and listens to music

In English, we would probably say:

• I listen to music with headphones on
• I wear headphones and listen to music

Korean -고 does not always sharply distinguish between after doing X and while doing X. Context usually tells you.

The dictionary form is 듣다 (to listen), but this verb changes when followed by a vowel.

This is because 듣다 is a ㄷ irregular verb:

• 듣다
• stem: 듣-
• before -어요, the ㄷ changes to ㄹ
• so it becomes 들어요

That is why:

• 듣다 → 들어요

Other examples of this pattern:

• 걷다 → 걸어요 = to walk
• 묻다 → 물어요 = to ask

But not every ㄷ verb is irregular, so this is something you usually learn word by word.

들어요 is the polite informal present tense, also called the -요 form. It is very common in everyday Korean conversation.

Different endings show different speech levels:

• 들어요 = polite everyday speech
• 듭니다 = more formal, often used in presentations, announcements, writing, or very formal situations
• 들어 = casual/plain intimate speech, used with close friends, younger people, etc.

So this sentence is in a very normal, polite conversational style.

Yes. Korean often omits the subject when it is already understood from context.

So this sentence could imply:

• 저는 지하철에서 헤드폰을 끼고 음악을 들어요 = I listen to music on the subway with headphones on

But if the conversation already makes the subject clear, Korean usually leaves it out.

This is very normal and natural.

Yes, Korean word order is somewhat flexible because particles show each word’s role.

The most neutral order is:

• 지하철에서 헤드폰을 끼고 음악을 들어요

But you could also say things like:

• 헤드폰을 끼고 지하철에서 음악을 들어요
• 음악을 지하철에서 헤드폰을 끼고 들어요

These may sound slightly different in emphasis, but the particles help keep the meaning clear.

Still, the original sentence sounds natural and straightforward.

In Korean, 지하철에서 simply marks the subway as the place where the action happens. English chooses between in and on based on natural usage.

So in English, both may appear depending on context, but:

• on the subway is often the more natural general English translation
• in the subway can also make sense, especially if emphasizing the physical interior

Korean does not make that exact same preposition distinction here. 에서 just marks the place of the action.

It can mean either, depending on context.

The -아요 / -어요 present form in Korean can express:

• something happening now
• a habitual action
• a general fact

So 지하철에서 헤드폰을 끼고 음악을 들어요 could mean:

• I am listening to music on the subway with headphones on
• I listen to music on the subway with headphones on

Context tells you which one is intended.
