I have the headphones compared to my nearfield monitors and my electrostatic headphones can test for which I seek to complement a mobile solution. I feel the phone as a relatively heavy, but the pressure holding him on the head. Bass, spatiality and perceived positioning of the instruments are ok. Unfortunately, the heights above 5 kHz must be strongly emphasized, which brought them a metallic sharp sound when hochtonreiche instruments come to play, in particular pool. In classical me also a slight Topfigkeit noticed in the middle.
Since the heights for me to make a permanent hearing impossible, I have returned the handset.
Addendum: In Beyerdynamic T-5p, I have now found the ideal for me listener. Less weight, less pressure and softer leather EEnter a better comfort. The T-5p is sonically balanced by the bass to the treble, free of stains, and so I prefer him before even my electric deeds. It is equally suitable for classical, jazz and rock and also on mobile devices loud enough.
