jupark123i have no knowledge for these headphones but the general consensus for the Z1R is that it's not very good, and that the bass bleeds into anything.
jupark123I personally love the Sony MDR Z7 .. IF paired suitably with a sufficient and efficient headphones DAC amplifier, they can be highly appreciated .. the music genre can often determine which headphones for which situation.
I used the dual 3.5 mm ( Balanced ) cables with Sony PHA-3 and they found quite good .. I've currently 9 sets of premium headphones and 4 premium portable DAC amplifiers and the Sonys rate right up there when playing HiRes music files via a USB music player via my Samsung Galaxy Note 9
