the review from some people on this site have I concern that upon use my new headphone , the cable would turn to jelly and the product would become worthless . that have not happen yet , and I be loving these headphone . they block noise out with the snug fit , and they sound great . I enjoy listen to all type of music , especially track with intricate , bass heavy beat , like those of Kanye West , for example . I be hold onto my warranty , which I believe be 2 month . so far , so good .
