Hello
I am an owner of a few Edition 9 for one year. For my sound a few excellent earphones. They have a very special sound that they they all will not like. The serious ones are controlled well and the means are fluid; the sharp(acute) ones, probably a bit scanty. On the other hand, I do not like the sound Degree. My other earphones of reference are the K1000 and the modified D5000.
I believe that they are ear that it is necessary to try before buying.
