How are 'nasalized vowels' pronounced?


I've noticed when listening to some recordings of ん before a vowel, such as
`万{まん}円{えん}`, that the ん sound tends to be assimulated and almost vanish into
the vowel's sound (sounding almost like まーえん). But there's just a hint of a
naselization I think is being said, but I can't seem to replicate it at all,
and pronouncing it with a ŋ ('ng') sounds stronger than the recording.

I've searched some of the past questions on the site related to how ん is
pronounced prior to a vowel, but I haven't found a response that really gives
a precise answer, as most say 'nasalized vowel' without many instructions on
how to actually pronounced it.
