I need a new pair of headphone to replace some raggedy Sony mdr-v600 's that be 18 year old and fall apart . after literally a year of lurk in headphone forum and come close several time to drop several hundred dollar on this or that , I stumble across someone talk these up . after use these for a month or so , I be absolutely floor by how much better these be than those old v600 's ! to my ear , these be fantastic headphone . some people have comment on the weight of these be too much , but I do not find that to be true . while these be at least 5 time heavier than the Sony 's , they do not feel that way on my head . these be very comfortable headphone . the bass be have serious authority , but these be not fart box . it be clean , powerful bass that be not overwhelming whatsoever with a flat eq setting . I listen to a wide variety of music include rock , metal , rap , and classical , and no matter what I be listen to , I feel like I be hear the music as it be intend . these need to be run from a receiver or a dedicated headphone amp , and the cord be a little short -lrb- a extension cord take care of that -rrb- , but these be home orient headphone , so that stuff do not really matter . these have to be the best value in this price range . with a lifetime warranty , how can you go wrong ?
