I recently purchase these headphone to replace a 139.00 set of bose headphone . these headphone blow the bose one away . year ago I own a set of the Sony mdr-5000 yet lose they somewhere . anyway , I be attract to the bose because of the name , etc. . they be however make very cheap and the wire break where it enter one of the earcup . the Sonys be the exact oppositte . they be build solid and exactly what I need . I play the drum and use they all of the time when play my electronic kit . the sound quality be far superior to the bose headphone and I be so happy I purchase they ! you will not be sorry if you do the same .
