Heel height above 3. 6/11/19 update. Had this for literally 1 month and it stopped working. Merciii Amazon cest super je ladore ,elle est magnifique, jolie, confortable 5étoiles youpi ???????? The only complaint about the headphones is after a short while my ears become hot and sweaty. Even phone calls, which are not important to me, work great with these. I?d give it 0 stars if I could. Now! My wife has this same type (HyperX Fury 2x8 16GB)and has had it for 5yrs. Metal is also present in the headband sliders, which are solid and lock nicely into place.
