Unfortunately, I have to complain about a few things. the headphones are of good quality. prima also that one can up to 32GB using a memory, but now the BUT: the title can not be random mix (shuffle feature), which means you can hear from the 1 - 200th title only in order ... boring. after switching on again and the selected sound mode is gone, so has to be readjusted. as eyeglass wearers annoying blinking blue LED on the ear as they constantly reflected in the spectacle lens and thus I go for a walk at night with the dog always have the impression that there would a car from behind .. if these "quirks" were not, top part price for this.
