How to tell the difference between high imitation magic ear headphones and genuine ones? Sounds the same. . . (head-mounted)

You can listen to some music with obvious low frequency and high frequency, such as black eyed peas and Vitas, and the difference should appear. However, I think, generally speaking, if you just start playing music, if you don't work hard for more than a few years, it seems that there is no difference between finding a headset with high recovery rate and listening to music with ordinary headphones, because most of the general pop music is in the music that is most suitable for flat-ear headphones. This is the judgment.
