Query: Wires Rot and Short!!

I loved the sound and the fit more than any other pair I've ever owned. They lack in bass but not a big deal to me. Loved them EXCEPT!!!! Within 6 months without fail the wires' insulation rots, gets brittle, and breaks. I've owned 3 pair because I like them so much, but without fail they short out. I'm nice to them too!! Sad because their fit design is SO GOOD! And sound isolation is the best I've experienced. If I was rich I'd just but 20 pair and go through them like toilet paper, but I'm not.VERY NICE..............SHORT LIFE.
