Query: Started out great, but completely died after a few months of use!

I usually don't write reviews, but I was so upset when these headphones suddenly stopped working. The product (when still functioning) was to my liking, as they canceled out noise and had a decent bass boost. However after about 6-7 months of using them (not even frequently, I might add) the wire right at the base of the headphones needed to be toyed with in order to not get static, or just the right headphone. It was annoying and once that was done, it stopped working completely and now there's no sound at all.I wouldn't spend your money on these. As much as I liked them, they malfunctioned way too fast.
