Yes the pair that broke is from the "fixed" revision. This probably explains why it broke in a different place.
I am currently not at home and once get back I will share pictures.
Just for the record I've used them 5-6 hours a week tops, for around 1 year and 2 months.
Also 2 pairs of the first revision broke before them.
Maybe it is flawed design or my head is too big, I do not know anymore.
