It's working fine now thanks.Try unplugging them, touching the pins on the plug with your thumb (decharging the stators) then go back to listening. Its possible the diaphragm is just stuck to the stators and this will release it. Worth a try.
I think it was just the way they were positioned on my head, the fit is really finicky especially with glasses! Someone informed me on how they should be placed on the head with the rotation of the cups and pads.
