My Bose IE2 needs to be rescued...please help!

Good day! Guys, i need your help on how i can still revive my beloved in-ears. It has been with me for more than 7 years and still don’t want to part ways with it. The rubber insulation of the wires are starting to disintegrate on many areas maybe due to old age but i still do want to keep it for longer. i’ve been a loyal bose fan for the longest time and i cannot find the same like these anywhere anymore. any help would be appreciated! thanks and more power!

 

i hope this link would work to give you an idea how it presently looks like..
