Also, I feel like Im charging these bad boys every couple of days, and I dont think Im using them excessively. Fits accurate to size. These started peeling after the 1st use. Ist ein 8pol. For me the height is also fine. l- Headphone jack incase battery run out and cant use BT- fit and finish is appropriate for this price, probably exceeds expectations. Good product so far for price. I have just returned to cycling again after giving up the old Dawes bike to a friend. For the price I will go back to ugg slippers. It is a bit weird because all the other Birkens I have I wear EU 38 without any problems.
