The headphones do a good, the price corresponding impression. Here can be in music mode titles not selected directly. To find a specific title, should be zapped from the first track. In a well-filled SD card with 32GB rather pointless. Therefore, for the headphones only 4 stars. Two stars I had to withdraw because the seller mitliefert no useful manual. In addition there is a further deduction for the "serviceability" of the seller.
