First Come, First Serve
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, elevate your listening experience to the one you can feel.
The Sony IER-Z1R use a hybrid driver system - three unique drivers in total equipped with Sony's special balanced armature drivers and audiophile grade building materials. The primary driver is a large, 12mm dynamic driver with a diaphragm specially constructed with a magnesium alloy dome. The second driver is 5mm, using an aluminum-coated liquid crustal polymer diaphragm and receives its power from an external magnetic circuit (helping to keep down noise and boost frequency response). The final driver is a balanced armature driver made from magnesium alloy. Each Sony IER-Z1R earbud chassis is composed of a zirconium alloy, making the buds quite resistant to corrosion and scratching, all while remaining comfortable.
Included in the box are 3.5mm and 4.4.mm audio cables. The cables are made from silver-coated oxygen-free copper, using a gold playing undercoat as opposed to nickel (since nickel can be magnetized and disrupt the signal). Sony has included a total of 13 pairs of ear tips, so you can be assured of getting the right fit. The Sony IER-Z1R also include ear-hangers in the design which are fairly adaptable and add to the overall comfort and experience.
The Sony IER-Z1R price certainly constitutes a premium experience in high-fidelity listening. Sony has gone above and beyond to ensure a product that faithfully reproduces your favorite tracks while perfectly controlling acoustics. A standard, one-year headphone warranty is included.
Release date: TBD (We are expecting our first shipment in the next couple weeks)
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.

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.

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.
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 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.
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 comfort and less touch-noise, the cable helps you immerse yourself in music on the go.
A 0.17" standard balanced connection cable separates left and right sound signals completely, which 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.
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.
