The worst thing is that the headband did not fall apart just as if it broke at the bottom and there is only a line at the top. An additional difficulty is that there is a cable in the headband connecting one earphone to the other. The gap is also very small so the glue can only be delivered with a syringe. In addition, from the bottom of the headband there is a "lining" - the material and I do not know if it can be removed somehow. I think that the best solution will be if I glue the headband with epoxy glue because nothing more will probably sculpt :(
If you have any idea or know someone who would be able to fix it professionally, I would be grateful
PS. it's a pity for the headphones worth 600 zlotys because they sounded beautifully and I would not exchange for any other
