After several flops respect headphones and some returns to Amazon (sorry) I finally got my long awaited Sennheiser HD 598. Hammer! Fine sound, easier and more pleasant, airy seat at the head. My parallel order placed - the m50x Audio Technica ATH I canceled right after this listening experience. Shortly afterwards came the news of Amazon that a cancellation is no longer possible, since the headset is already on the way. Well, then just resend, if it's there. Today it was time. Somehow it has then attracted me to try out these headphones and suddenly went to my ears! An aural orgasm first rate. The headset is decidedly cheaper than the Sennheiser - but better in the accessories provided. He sits much stronger and felt closer to the head than the HD 598, which conforms with soft suede (the felt nicer headphones). Also, the Audio Technica is decidedly more difficult. But through all of this can be seen across when you listen. From the deepest bass in hard techno to the finest strings in the classical area - here everything is cleanly transferred. At Sennheiser there despite Audio Engineering Made in Germany (incidentally manufactured in China) slight "buzz" with bass and throughout the "tilt" of the sound in the tops off - the headset comes up against its limits. The Audio Technica is at the same pieces at the same volume yet in full momentum here.
Who wears the headphones very long, does not hear very loud, emphasis on high quality workmanship and good material or simply want to buy fashion-conscious, I advise to Sennheiser HD 598 - a hot part!
Who can deal with a little pressure at the top, has no problem with the typical pseudo-leather cushions and neck muscles enough to bear the heavier something ATH m50x, which is a listening experience in a class of safe :-)
