I have gained these headphones, because I have had very bad experiences with my Monster in Ears and these were broken after 3 months. That's why I switched to Sennheiser, also because of the 2-year warranty, and have to say that I'm thrilled. The sound of these headphones is simply top class. I am not a DJ, but I think to be able to claim to be able distinguish good from bad headphones. Therefore I a strong buy recommendation.
