Query: Great sound, comfortable, but cord deteriated in six months

I love the sound quality. The ear buds fit snuggly yet comfortably in your ear. But after just six months the soft rubbery cord started deteriorating. Now the two little wires inside are exposed in many places and the headphones are shorting out. Definitely not worth the money for the short life span.
