I GUESS, that mineīs are Innate, but mixed with some trainning.
well i do this way : i get a riff, 4 notes sequence. power chords for an example.
First, i certify myself that the song i m trying to learn by ear is Tuned the same tune as one of my 3 guitars(E, c or D) if not, iīll find out, by ear, trying to find the low E string played alone and trying to find what note is that, and then.. i tune my acoustick or a cr@p guitar, to that tune, and then i start by trying to find where it the first note of that 4 notes riff.
and then i find the others.
but , you need to know some examples.. i mean, someoneīs have to show your your first steps first. cause, without refference, itīs a lot hard .
Q:)

i just play by ear, i donīt know nothing about music theory, except the notes names.
no harmony or melody stuff.. no timing, but i have my own timing by learningn song by ear.
