(~5 full hours/day)I appreciate a good isolation level and the one provided by this headset is nice. Je recommande fortement Over-all, for the price, these arent bad shoes to be wearing in the kitchen. , but maybe I should have returned them, because I dont use them to talk over the phone at all. I have wide feet and did not find this to be the case. The primary problem with these flip flops is that where the straps enter the sole between the toes is set too far back. Just dont go swinging it around like a flail and itll last you a good, long while. That extra $100 will easily justify itself after years of listening pleasure! I work at home so I wear these as my house shoes. As far as the headband, Im not sure what I can do.
