The sound it was making seemed like it was going to. It still looks brand new - I sometimes spill on it but I just wipe it down to return it to its like-new appearance. I?m pleased with the lightweight feel and secure grip. Great arch support and enough of a heel to make them even more comfortable. Battery lasted for hours! Should fit most headphones. Now even quieter classical pieces are listenable, and almost all music enjoyable. But it is a joke of poorly thought out implementation. I will not be buying Birkenstocks from Amazon again. I may decide to have two sets of slippers.
