over stretching the headband returns to shape. This may also affect the seal resulting in reduced noise cancellation effect, though I am unable to tell because my original cushions lost all their pebbled faux leather spray on coating and all I have are just plain foam and overlying cloth which reduces the noise cancellation due to sound leakage. overall good headset. I?m very disappointed on how they can charge the same price for a knockoff. Save yourself! )Overall, highly recommend it. Most likely a 10 1/2 would fit me perfectly, but half-sizes are not offered. Compre estos audifonos por que ya habia adquirido hace un año los t3 y habian salido buenos. I have used my brands of high dollar headphones and these are just as good for a fraction of the cost! If you dont need regular access to that button, this is a great case.
