听不懂没关系
Reach for this when you want to reassure a listener that not understanding is fine. It's a fixed beginner-friendly phrase teachers, narrators, and parents use to lower the stakes before they keep talking. Structurally it's '[can't understand] + [doesn't matter],' two short clauses glued together without any connector. You'll hear it constantly at the start of language podcasts and explainer videos targeted at learners.

How to Think About It
听不懂 is a potential-complement negation — literally 'listen-not-comprehend,' meaning 'unable to understand by listening.' 没关系 is 'no connection / no relation,' which idiomatically means 'doesn't matter.' Together they form a one-shot reassurance: the speaker preemptively forgives the listener, so the listener relaxes and keeps listening instead of giving up.
Examples
听不懂没关系，我再说一遍。
Tīng bù dǒng méi guānxi, wǒ zài shuō yí biàn.
If you can't understand, that's OK — I'll say it again.
听不懂没关系，慢慢来。
Tīng bù dǒng méi guānxi, mànmàn lái.
Not understanding is fine — take it slow.
今天的内容很难，听不懂没关系。
Jīntiān de nèiróng hěn nán, tīng bù dǒng méi guānxi.
Today's content is hard; it's OK if you don't understand.
Common Mistake
Learners write 不听懂 instead of 听不懂. In potential complements, the 不 sits between the verb and the result, not before the verb. 不听懂 isn't grammatical Chinese.
不听懂没关系。

Don't Confuse With
看不懂
Same structure but for reading — '看不懂没关系' for written text you can't understand. Pick based on whether the input is heard or read.
没听懂
没听懂 = 'didn't understand (this time).' 听不懂 = 'unable to understand (in principle).' Reassure with 听不懂 for the general inability.
没关系 alone
Just 没关系 is 'no problem' after someone apologizes. The full phrase 听不懂没关系 specifically forgives the listener in advance.
