We bought a little over 24 months of our daughter on the zealous insistence Beats Dr. The to a whopping 299 euros !!! You have the guarantee period barely survived and it was. To be able to test the Sennheiser was so super class because we did not grasp the intention again so deep into their pockets. I have to say, here, the nearly 200 euros would have paid off ...... Our daughter is amazed at how much better the sound of headphones. Processing and packaging (actually uninteresting, but Dr Dre also waiting with great packaging on) are second to none here. The wearing comfort is also excellent, nice and light, super sit at the head and especially you do not sweat. Technical explanations and descriptions have been around in heaps, so I consider myself as back, I can only say, and as I speak for my daughter: We do not miss the Beats by Dr Dre, the Sennheiser Momentum On Ear is absolutely great !!!
