Hear astonishingly faithful sound reproduction with the IER-Z1R In-ear headphones. A custom high-resolution HD hybrid driver system and Refined-phase structure, along with the sonic purity of a 0.17" balanced audio connection, elevates your listening experience to the one you can feel.

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.

Sony IER-Z1R 0.20-inch 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.

Sony IER-Z1R 0.47-inch driver

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.

Sony IER-Z1R balanced armature driver

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.

Sony IER-Z1R network

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.

Naturally controlled acoustics

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.

Sony IER-Z1R tweeter

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.

Sony IER-Z1R stock cables

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.


Sony IER-Z1R signal paths

Balanced connection

A 0.17" standard balanced connection cable separates left and right sound signals completely, which minimizes cross-talk that results in sound deterioration.

Sony IER-Z1R stock cables

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.

Sony IER-Z1R stock cable structure

Silver-coated oxygen-free copper cable

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.
