Question her: I expected to have a mush infamous but not !! a helmet with a very correct and honest sound, no specific gaps, overall the whole spectrum is there.
It's not a helmet "Basseux" as was the XB500: it has good bass, but are not exaggerated, like the rest of the spectrum. It can adapt to all styles of music but that have too many sounds at once, on some tracks, the helmet has a little trouble to show accurate, it will certainly revisit this after running-judgment (eg rock ).
Comfort: extremely comfortable, it heats some ears but it's still very widely acceptable!
Anyway, who wants a stylish and comfortable headset with excellent sound without exaggeration, up to 25, I recommend it!
