I was only impressed by the design ... The "Marshall" logo made me old memories of old belt-hours. In business I could connect my phone and immediately at the first music I was sold ... I had Alan Parsons Project and it sounded like one actually knows it only in-ear headphones ago. But that is certainly the fact that the speakers are quite generously sized and the two shells very tightly enclose the ear. Poets do not go. :-)
The sound I feel as pleasant as the mid-range frequencies are not very stressed which can vexing the ears depending on the music, and a longer listening is therefore not a problem.
Compromises you have to make classical music which can "musty" fail depending on the shooting and the higher dynamic range.
Solid they are already the headphones but ... I am once woke up and one of the two shells had come loose from the strap ... I only imagined as a disaster but turned out to be a godsend eigenlich out, because there where at similarly priced (and expensive) mounted Kophörern the bracket or the bracket breaks, are here simply by design the holder to beschädgen the mussel-free without them, it is then easily reattached and "nix iss happening".
Price / performance ratio is really strong. :-)
Would I buy again immediately and recommend.
