This headset is used for gaming and music listening. I?m a size 6 and while the length is perfect, the width of the shoe is a bit narrow. A niggle is that there should be more than one custom EQ slot, but perhaps they can add that in a firmware upgrade. Purchased for a fishing trip. They?re very nice, just not what I ordered. Note it is a little thicker than the non-replaceable battery model it replaces. Go watch! Both ankles were bleeding by the time i got to the coffee shop. This isnt horrendous but it could be fixed by just centering the velcro strip segment at the top of the unit. These were pretty intense hikes with little places to lodge my toes into to climb, and they wore well and provided great traction to get me where I needed.
