I do not expect a big change in its at best a slight improvement. What a surprise to hear such a decrease bass!
In fact, the problem is not with the components (which from what I've read are pretty much the same as before), but the remoteness of the speaker of the ears because of insulating foams.
It's simple: by slightly pushing the two arches on the ears, the sound is excellent, as I would have liked: bass at least as good as those of the PX-100 and a notable improvement from the rest of the sound frequencies. Unfortunately sometimes I need to use my hands when I listen to music.
This is particularly frustrating that this issue is silly, it would have sufficed that the greenhouse helmet a little head or putting thinner foams. I read that some headphones had to be honed before producing their optimal, but personally I do not believe this has never been proven and anyway the lack of bass is too important.
It shows sound far less pleasant than before, I will make a return, which displeases me because I really love this brand. So I strongly recommend to the owners of the PX-100 1.
