Theese headphone be so sick !! they have great sound , look amazing , and be well worth the money ... the sound leakage be not as bad as people say unless you have it on full volume . the battery last a really really long time ! the only thing I would like improve be the noise cancellation ... I own a pair of Solo HD 's too and they block out almost as much as the studio even though they do not have noise cancellation . I would defiantly recommend this to someone who like quality sound !!!
