Sony - 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.

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 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.

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.

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.

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.

Expertly crafted in Japan

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.

The King of IEMs

Many contenders for the throne have arisen, but none has surpassed the bold, colorful musicality of the Z1R. The design and fit (yes, the fit) are also unmatched.

TOTL Sound

An excellent iem, best bass you can buy in an earphone. Mids are slightly thin, and treble can be somewhat sharp. Top tier iem, unfortunately had to return because fit was not good.

Outstanding sound, Fit could be challenging.

Absolutely love them. They sound somewhat similar to Campfire Audio OG Solaris. Z1r is more forward in bass and treble, a little less in mids. Slam and punch come to mind. The bass is so clear quick and concise, as is the treble. Mids are equally clear and detailed just back a little more. If these fit, buy them.

Amazing Sound Quality

I paired these balanced earbuds with my Sony NW-WM1A DAP and really heard a difference in audio quality. Been using it frequently to play hi-res music files - I heard bits of instruments that I have never heard before in previously played songs. Build quality is amazing and the presentation of the packing is topnotch. The housing themselves are solid metal and made in Japan - you can feel the quality. One thing to note - the buds themselves are fairly large and have heft to them. I can definitely see these being a bit large and uncomfortable for people with larger ears.

Something Special

I don’t recommend purchasing these second hand. Buy new from audio46.
