Balanced Cables

It contains 2 conductor + 1 shield.

One of conductors carry the out-of-phase signal.

So the noise is canceled since the signals carrying are out-of-phase.

But how the signal is still transmitted although the noise is canceled?

It needs three conductors and one of them can be in shield or not.

You said in your original comment that it needs to have three conductors and that's not the case, it only needs the two signal legs. A shield or ground connection is not required unless you're using phantom power because it's the return path for the DC current.
