IER-Z1R Signature Series In-ear Headphones
One Signature Sound
Elevating the high-resolution sound experience from one you listen to, to one you can feel.
Learn about the technology and inspiration behind our most premium In-ear headphones, the IER-Z1R.
We designed the drivers in the IER-Z1R headphones from the ground up, to work in total harmony together. The consistent sound signature carried out across each driver works as if they were a perfect single driver.
The super tweeter is on a coaxial position against the nozzle. This layout directly delivers accurate super high notes to your ears, with an ultra-wide frequency response up to 100kHz.
Time coherence of the sound from the three drivers is just as important as their wide frequency response. The Refined-phase structure ensures sound waves are aligned, through precision adjustment of the width and length of each sound path. The magnesium-alloy construction also further eliminates vibration and unwanted resonance, to deliver perfect clarity and liveliness across musical genres.
For balanced sound, from low to high frequencies, an acoustic tube connects to the cavity behind the driver unit. This technology presents a wide sound space with rich and natural notes.
Engineers didn't overlook the quality of the supplied cable, which releases the full potential of the IER-Z1R. From sound quality to wearing comfort and less touch-noise, the cable helps you immerse yourself in music on the go.
A 4.4mm standard balanced connection cable separates left and right sound signals completely, which minimises cross-talk that results in sound deterioration.
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.
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.
Settle for nothing less than immersive excellence with the full range of Signature Series products. Designed for ultimate sound quality, they transcend audio conventions to elevate every note.
With 360 Reality Audio certified headphones and the Sony | Headphones Connect app, optimise your experience by analysing your individual ear shape, and enjoy the ultimate immersive music experience.
