>Accurate Motion Air Damper
JVC’s proprietary air damper ensures precise diaphragm movement for accurate sound reproduction.

Fine Adjust Mechanism for Optimal Fit

To accommodate individual differences in ear shape, a Fine Adjust Mechanism is employed, allowing the nozzle to rotate 360 degrees. This enables adjustment to the preferred angle, supports both standard and over-ear wearing styles, and ensures an optimal, comfortable fit.

Features a detachable groove cable with MMCX connectors

Equipped with MMCX connectors for easy cable replacement. The specially designed groove cable helps prevent tangling while improving durability for everyday use.

J-Mount Interchangeable Nozzle System for Sound Customization

This model features JVC’s J-Mount Interchangeable Nozzle System, the industry’s first* to include multiple nozzles made from different materials for sound tuning. By swapping between three precisely crafted metal nozzles—titanium, brass, and stainless steel—you can enjoy subtle but distinctive changes in sound character, allowing you to tailor the audio to your personal preference.

Comes with Newly Designed Spiral Dot+ Earpieces

JVC’s acclaimed Spiral Dot earpieces use precision dimples to reduce internal reflections, delivering clearer, more natural sound.This model includes the advanced Spiral Dot+ earpieces, featuring both a newly developed material and a refined shape for even higher performance. They adopt SMP iFit, a new material with mechanical properties similar to human skin. This minimizes unwanted resonance and provides an exceptionally natural, comfortable fit—so seamless you’ll forget you’re wearing them. The newly optimized shape further enhances sound expression and overall audio clarity.
