How is the user experience of HIFIMANDevaPro Flat Panel Headphones?

The user wearing experience of the HIFIMANDevaPro flat panel headphones is relatively comfortable. In the actual wearing experience, HIFIMANDEVAPro and the first generation of DEVA's difference is not too big, but vaguely feel DEVAPro will be slightly lighter, not sure if the engineers have further optimization of the headset, but this wearing feeling is really comfortable, even if a long time listening to the song, there is no kind of auricular compression.
