Very good product that is robust to support the passage of many years.
High-quality printing. Good wire length and diameter correct.
I wanted a closed headphone listening to music without disturbing.
It was my first headphone in this price range, I was really impressed with the sound quality. Clear highs and accurate bass without aggression and breathtaking without being predominant. I have not seen any effect "surround" ... and that's fine like that!
Its only flaw is that too shook my big head and hurt my ears in 20 minutes. I, to my regret, returned because of it.
Very nice sound, to be reserved for small heads (no pun intended).
