Right ear diaphragm is crinkling.

Recently (after about 1 month of use) my cloud orbit s headphone's right ear's diaphragm has started crinkling.
I read that this is due to air pressure, but am unsure if there is a way to fix the issue.
I am willing to take the headphones apart and attempt fixing them, but I am not that experienced with sodering.
anyone know how I can stop the crinkling?
