In short with this headset I saw: there are more than 5 decibels on my AKG (which I did not find strong enough sometimes I like to push the volume build on my favorite songs) / The sound is just as good ... I do not perceive any significant difference (possibly a little on the grave) ...
I easily fit in my bag without fear of node that will indemelable (by cons attention not supplied pouch for storage)
And in addition there is only ONE thick wire left that s not tangle as c is the case with other brands.
It is very beautiful black and brown leather (or immitation? Ca has natural air) and a nice finish on the inside with Marshall golden plates and outside.
Unlike the AKG does not hurting the ears (it fits well but not crushed ears, I can wear it with my sunglasses I have not hurt) I specify that I jog and with that it does not fall short ... as qualities !!
