The headphones look really good, even the Gummipömpel to insert into the ear are good. The three sizes to fit somehow supplied for each. For sound, judged from a musician point of view: Super !! Treble, mid and lows are very clear. Downs have good pressure, only at high volumes catch the earphones to override something. I contend, however that no one will hear in such a volume in the long term music with earphones. Why only 4 stars: The price. The sound is great, no question. They are high quality and I would not even want to miss. But I believe that a lower price would be acceptable for this purpose. Conclusion: In spite of the price strong buy recommendation!
