Sound like crap. Some of the most out of place treble and grainy headphones I've heard from Beyer, even if they are £150 I'd still say don't.
Nad Viso HP50 £175 - Good balance from bass to treble, really nice tonality, good bass extension and excellent treble articulation.
Focal Spirit Classic £250 - My fav sounding closed headphone. Amazing tone, like dark chocolate, thick, smooth, good impact - the fit on these is a hit and miss, they bothered my piercings a lot.
Oppo PM3 £359 - Very nice headphone, good detail and resolution, build well, not my cup of tea for sound signature but I appreciate what it can do, not really a warm headphone but pretty even sounding.
