Expertly crafted in Japan

Sony products made in Japan are synonymous with absolute quality and performance, and the IER-Z1R headphones are no exception. They are lovingly crafted with only the finest components and manufacturing techniques, resulting in exceptional sound quality.
  • Balanced connection

    A 4.4mm standard balanced connection cable separates left and right sound signals completely, which minimises cross-talk that results in sound deterioration.
  • Silk insulator and non-magnetic plating

    Silk braid in the supplied cable reduces touch noise and works as an insulator against vibration. Using twisted pair wiring and a non-magnetic undercoat for gold plating on the plugs ensures legato and clean signal transmission.
  • Silver-coated oxygen-free copper cable

    The IER-Z1R uses silver-coated oxygen-free copper wire, designed to minimise resistance and signal-transmission loss. The result is less sound degradation, finer detail and smoother treble sounds.
