You can bend the headband. That's exactly why you don't think its comfy. You can bend it so it perfectly follows the curve of your hand. I have a friend that wear his where it only touches the very top of his head and that bothers me a lot.
How did you install yours? I left the original Audeze rings in for rigidity and taped the pleather directly to the cups completely ditching the Hifiman rings. I don't remember noticing any loss in details, but it did slightly de-emphasize the treble if you're coming from stock pads. I did my mods in reverse order to you so what is relative is different too!
