Worst muffled background noise and too big

Wanted my headphones just buy for jogging, the sound quality was not even very important to me. But jogging can be so completely forgotten, because you can hear every step as dull loud background noise, so you can not hear the normal sound undisturbed. Even if the cable - as usual while jogging - slides on T-shirt along, you can hear the muffled as unpleasant sound. Jogging is so impossible! And now I have not judged me as a demanding person.

Furthermore, the strap of headphones are indeed "größenverstellbar" but are probably built for Elephant ears. Have a normal female ear, but that they are about 2cm addition (with fully zoomed out), but is probably a joke !!! That might not even fit a man with big ears. Keep doing naturally anyway - yes stuck deep enough in it, but with normal in-ear headphones you would be better served. The bracket is therefore completely wrong and useless !!!

Utter bad buy, hands off of it !!!!
