Surprisingly, the headphones came after one day. He works well. Battery performance is as described. He works as an MP3 player, radio or just as headphones very well. The manual has been updated to match the device match. It is a pity that the songs will be played in the order they are stored on the Micro SD card (so no shuffle mode) is. It is always started with the song, in which one has stopped the last time. Since the headphones are quite small, they are by wearing some getting used to. But otherwise super sub: D
