My last pair lasted 5 years. However, the biggest issue is the left and right mouse buttons. Super, comfortable for walking too. I did not keep the statue because of these issues and submitted a return. Los Bose son los únicos de la lista que aprietan y tienen el giro al contrario que el resto. UNTIL they stretched out! I think the plastic is thin so a certain amount of noise gets in. I am a size 5 but i got the 35 size and it is a perfect fit. However, I had the same problem that a few other reviews noted - an uncomfortable pull around the outer edge of the foot hear the baby toe, where the strap closer o the toes straps across the foot. Great camera, great capacity, very bad conectivity.
