I usually wear a 9M in all shoes that I own. This is a complete misrepresentation! This may be because my head is small, so the pressure on my ears isnt a much as it would be on someone with a wider head. Im using them with my HD600 both as a digital coax and analog interconnects from DAC to amp for tv and movies. Thought it wouldnt do it but its silicon or some stretchy rubber that expands. Did not have this issue when the soles were actually leather as advertised, instead of Nubuck PU as listed on the label. Wearing a pair of boots 5-6 days a week in my job most can become worn out within 10-12 weeks and start letting in water far sooner these boots are of superior quality without a doubt , But please note I have looked after them I apply dubbing and G-Wax twice weekly and they have served me well and kept my feet dry . Corded mouse. This headset is just perfect. I also tried her new Yootech Charging Stand on my new iPhone XS MAX and it also charges to 100% while we sleep.
