IER-Z1R Signature Series In-ear Headphones

Sony IERZ1R

Features

  • To deliver music with true emotional impact that takes your breath away; every element of the IER-Z1R headphones has been designed and developed for this one purpose. By paying attention to the smallest details, you can distinguish every nuance and subtle characteristics, in astonishingly faithful sound reproduction.
  • 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 in the IER-Z1R was developed to deliver ultra-high frequency extension with a new aluminum-coated LCP diaphragm and external magnetic circuit. Its ultra-fast response faithfully follows the fast dynamic transience of music, which provides you with live concert hall atmosphere.
  • Inheriting MDR-Z1R's diaphragm structure, the 0.47" dynamic driver's diaphragm consists of magnesium dome and aluminum-coated LCP. This full-range driver offers deep bass and fine mid-high sound.

Signature Series

One Signature Sound

Elevating the high-resolution sound experience from one you listen to, to one you can feel.


Discover the IER-Z1R

Learn about the technology and inspiration behind our most premium In-ear headphones, the IER-Z1R.


Originally designed to make you feel

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.


Hear everything with a frequency response to 100kHz

The super tweeter in the IER-Z1R was developed to deliver ultra-high frequency extension with a new aluminum-coated LCP diaphragm and external magnetic circuit. Its ultra-fast response faithfully follows the fast dynamic transience of music, which provides you with live concert hall atmosphere.


For deep bass and fine details

Inheriting MDR-Z1R's diaphragm structure, the 0.47" dynamic driver's diaphragm consists of magnesium dome and aluminum-coated LCP. This full-range driver offers deep bass and fine mid-high sound.


Faithfully reproduce every note

The newly developed Balanced Armature driver is equipped with a magnesium diaphragm, silver-coated copper voice coil and gold-plated terminals. These realize high definition sound that reproduces even the smallest fading note.


Audio grade capacitor without distortion

Developed from thousands of listening tests, the dedicated film capacitors on the network give much lower distortion. Audio grade solder is also used throughout to ensure maximum signal transparency.


A perfectly straight sound path

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 100 kHz.


Refined-phase structure for accurate acoustic blending

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.


Sound Space Control for wide sound space

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.


Quality cable for preserving signal purity

Engineers didn't overlook the quality of the supplied cable, which releases the full potential of the IER-Z1R. From sound quality to comfort and less touch-noise, the cable helps you immerse yourself in music on the go.


Discover the Signature Series

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.


So immersive. So real.

Immerse yourself in sound all around you. As real as if you are there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real.

These headphones let you enjoy 360 Reality Audio.

  • The vast experience and sense of our engineers is the key to acoustic design, which delivers the most natural sound. The finely tuned IER-Z1R acoustic structure steers audio from the trio of driver units as though they were a single, ideal driver.

  • The IER-Z1R in-ear headphones come with a 0.17" standard balanced connection cable which separates left and right signals completely. This minimizes 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 minimize resistance and signal-transmission loss. The result is less sound degradation, finer detail, and smoother treble sounds.
  • 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.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
