Funny because someone up there is also claiming the sound between the M50s/LE and M50s (regular) are different; claiming the LEs are better and the scientific reason behind it was the "magical" paint that improves sound quality (amazing rational thinking). You want to test if the paint won't chip try and drop it in a rough surface, let's see how brave can you be. Accidentally mine got hit and that right there is a genuine picture of a paint chip on the M50s/LE ANV, hotshot
The next thing, I want to hear is that the WS55 black and red sounds differently, because of the paint. The Ferrari car in red is faster than the black because it's in red. Okay, I got your point.
Evidence is your friend, if you are in the court of law, you've lost already with such reasoning that you "trust your ear better". Nobody believed the boy who cried wolf.
