Fibre Optic cover borken AX360

[emcp]

hi, i recently bought a pair of AX360

and i removed the fibre optic cable, very gently
nd i couldnt believe that the cover that protects the port broke of so easily

im wondering if anyone else has has this problem, if they managed to fixed it
and how much of a threat it would cause to the quality

i also might aswell ask this hear
what audio settings should i have for them on the ps3, at the moment i have checked

dolby digital
dts
aac

thanks
should i send the headphones back, who should i send them too tritton or the shop i purchased them from

id prefer to fix them myself, as i dont want the bother of sending them away, and i use my ps3 almost every night

thanks again
