Excellent headphones, good bass, not to hurt the ears over time (three or four maximum)

Excellent headphones, good bass, detachable cable even though I did not detached;)
The only problem are the accessories (HA 450) that cost half the price of the helmet! HA = 450 airplane adapter, microphone cable, etc ...
It is not too hurt the ears over time (three to four hours) and I wear glasses.
I use my mobile phone (android) with the original cable (without microphone) audio (music or call) is impeccable and clear.
The helmet is powerful on laptop I have to put her in third because if I blow my eardrums.
It is minimalist and strong I use it almost every day but I cherishes and protects the good cases even if headphones take up space.
