Okay, just nevermind. I just did a splitter setup with my signal to be able to hear both of them at the same time, and yeah, I can clearly say the AE sound is congested compared to that of the FA-002w, the bass is less impactful and the sound is less detailed, the voices are somewhat artificial and there is also less soundstage. The soundstage doesn't have this deepness that I only found in the FA-002w. There is also less separation. Well, in fact, they are just lacking on many things compared to the FA-002w. Next time I do a comparison, definitely going to go with that setup again, because when you try a headphone, then unplug it and plug the other one in, you quickly lose the memory of the sound
Edit: Wow, okay the FA-002w are indeed way better than the AE in so many ways.
Edit #2: Just tried a ultrasone demo and wow, the FA-002w just blows the AE out of the water. I'm sorry, I'm really a beginner to that stuff
