I have been using Beyer DT 770 Ms in the studio for ages and like them, they were designed for drummers and FOH engineers so their isolation is quite good.Have only used the Vic Firth headphones and for me they don't do justice to bass guitars. For example the crucial overtones of Fender P Basses seem to be missing!
So I'm searching for a replacement too.
Has anyone tried the Beyerdynamic DT 700 Pro X ?
