I had already several models, including Sennheiser and often the headphones either uncomfortable or you can hear the smallest error in the playback via markedly (was with the Sennheiser so). This product, however, enchants with a soft, clear and pleasant sound with excellent comfort even after hours of use. The cables also have a special technology to prevent accidental entangling which works very well and the removable extension is very pleasant in this price range.
I would always buy again and maybe I give even 1-2 specimens in the family for Christmas :)
