Time will tell how durable these are. The SE7 do not shift around at all. Somit habe ich mir jetzt die Willful T7 Bluetooth Kopfhörer in Ear bestellt. what can I do?????Later: Just back from a local Ecco Store. There are no links to the main site and now I?m stuck with a useless undamaged non working 10? cord. I?m always dismayed when I see plastic bags, trays and unnecessary packaging when I?m unboxing things. So far Im happy with this product. My daughter has abnormal feet & wide Birkenstocks were the only shoe she could wear. I spend all summer in Skechers so when I came across these I just had to try them. The packaging box is fancy.
