Unlike in the user manual (only available in English), the headphone elements on actual product can not be removed by a Velcro on the small pockets in the headband. This is a cleaning after use, for example. In sports, not possible without the elements by moisture possibly damaging. To fit on the head: The headband sits firmly, the headphones are not blurred even with more impulsive movements. For use during training to avoid possibly the most reliable way of dropping or Slipping headphones. However, the electronics are located in a minimally padded case directly to the ear, without any anatomical adaptation. The larger the head of the user, the higher therefore the pressure by approximately matchbox sized box on the right ear. The left element is more comfortable to wear, but also by no means comfortable. I have returned the product and will prefer an alternative.
Packaging, shipping, etc., as usual with Amazon without problems.
