Great item !! The quality of materials used is very noble and also the sound makes me happy. The stainless steel bracket, coated with genuine leather, the listener presses the beginning very strongly and permanently unpleasant on the ears. This can be avoided, however, since you can turn and adjust the bracket apart. Criticism is the description, which is totally inadequate, and for someone who has little technical understanding, not to be understood. Unfortunately, there is also the Internet no. The manufacturer should enclose a Detailed Description or at least make available for download.
