It's difficult to get glue to stick to the stock rubber headband, for sure! I installed an HD-600 headband cushion on a set. The best I've been able to achieve is by using high viscosity super glue plus super glue accelerant. Other brands probably work just as well. You just have to accurate when joining them And fast because the bond is Instant...so, no easy adjustment if you get off center. Good luck.
