  • In pursuit of perfect sound
    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.

    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 aluminium-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 12mm dynamic driver's diaphragm consists of magnesium dome and aluminium-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 realise 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.

    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.

    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 100kHz.

    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 wearing comfort and less touch-noise, the cable helps you immerse yourself in music on the go
