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.
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.
A 4.4-mm 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.
