great sound, super light!

I just got this headset and I rely on amazon commantaires which said a lot of good, and they are right! really very satisfied with the product, deep bass and good balance in the mid and treble (I use it with my ipodtouch and I put them on égualiseurs tonaliter for more scale is a must!) I had a Koss porta pro sound as beautiful but too fragil at the jack on vera if the hold out! in any case it is gone, it is good in all styles if musicos which is rare for a headset of this price, the aestheticism is caring and pleasant to wear as very lightweight (60 grams!), I also a koss ktxpro 1 the évoluiton pro bore which has a huge sound! pity he is not better known than AC because he deserves largment autan than others, now it's a matter of taste, koss or Sennheiser? We both leading headset offers product diferent meme qualiter but it is a certainty.
