Headphones

My order of Phillips SHP9600 headset came in today. I like the sound of it but the ear cups clamp way too damn hard on my head. My head hurts so much right now after only a couple of hours of wearing the thing. Every review I read said the 9600 has very light clamp but it feels near crushing levels for me.

To people who own or used this headset before. Did you experience this level of high clamp like me? If you did, does it loosen up over time the more you wear it of did it never go away? Should I just return the set if it’s hurting my head this badlyy or try to tough If our til they loosen up? I have a really big head and told these will fit me very well I’m worried about doing permanent harm to my head if I keep wearing it. I need some aspirin.
