I never imagined the kh worried because I'm an ear schwitzerin. so are my old Senheiser (was super happy with it) unfortunately - always slipped out of the ears - the sport. at the beginning of the KH are some getting used to and it does briefly hurt, but if you take the rotating raushat (in the truest sense of the word) - you have to have super goofy do that kh go out. then is also the slightly pain away. bullet-proof seat! for 100 points Sound: 90 points - could still be a track be better - but I am happy! no volume control on the headphones - unfortunately a small point deduction Well and with headgear in the winter / or sometimes even in summer, it can lead to slight problems because kh yes side sticking out of his ears. it is also a point deduction. otherwise well suited for the sport - to chill out on the beach or in the hammock could be adjusted selbige problems like headgear!
