Ideally, you want you heal to be just short of the back stitching, to get the max cushion. I have been wearing them in doors for over 2 weeks on ceramic floors . Overall, these are very good headphones for the price point. Leí muchos comentarios aquí acerca de lo reducidos que eran y que debería pedir una talla arriba pero la verdad es que a mi me quedaron perfectos. I figured it out right away. Works well and I?m glad to have them, The range isn?t great, really only useful around the house most of the time, I?ve already used them several times since I?m always looking for my car keys, I have a bad habit of misplacing them. I ordered this thing and I LOVE it. Have to get out the goo gone to take off the remaining adhesive. I tightened the elastic and retied it to customize the fit. This is an excellent device.
