I think this be a update model of Sony mdr-ex76 . as Sony mdr-ex76 , this mdr-ex86 's sound be pretty good . it be quite natural and clear . however , one problem with mdr-ex86 be that it discomfort my ear because of its bulky phone part . after 3-4 hour of its use , it really bother the inside of my both ear . probably , my ear have a problem . because its sound be not greatly different from mdr-ex76 's sound , I still like mdr-ex76 .
