The specified delivery date has been exceeded by far! I ordered on 11.25.2014, as a scheduled delivery date of the period between the 4-22.12.2014 was given to me. I have planned to give away for Christmas, but it is arrived at 06.Januar.2015. Very annoying! So I keep it myself and tried and the quality in my opinion is not exactly the best. On the one ear, the sound is much louder than the others, although various headphones have been tried. I'd rather invest soon 10 Euro more and buy it with me on the spot.
