The Story Behind ITO

DUNU is widely recognized as one of the finest names in the HiFi audio world. Kaji Kaji, known as Koto, is a top Japanese headphone content creator with a devoted audiophile following. HiFiGo brought these two forces together with a singular vision: to craft a high-performance, accessible IEM that doesn't compromise on artistry. The result — DUNU x KOTO ITO — is a brilliantly designed, finely-tuned pair of earphones that brings a musical, rhythmic soul to every listen.

A Quad-Driver Hybrid at Its Core

The ITO's quad-driver hybrid architecture is its defining strength. Dual dynamic drivers handle the low and mid frequencies with authority — the 10mm bio-diaphragm unit delivers deep, impactful bass, while the 8mm LCP-diaphragm unit covers mid-bass and midrange with precision. Two independent balanced armature drivers take over in the treble and ultra-high frequency regions, ensuring crystalline clarity and high-resolution detail retrieval across the entire spectrum.

Finely Tuned for an Immersive Sound Profile

The ITO is perfectly voiced for rhythm-driven genres. Its dual-DD foundation delivers a satisfying bass punch and rumble, while the midrange remains clean and articulate. The dual-BA treble section adds sparkle and air without harshness, resulting in smooth, detailed vocals and a three-frequency presentation that feels both engaging and natural.

Premium Stock Cable for Pure Signal Transmission

Bundled with a high-purity silver-plated single-crystal copper cable in a 22AWG Litz braided structure, the ITO ensures clean signal transmission from source to ear. DUNU's patented Q-Lock Quick Switch system allows effortless termination swaps between 3.5mm single-ended and 4.4mm balanced — the same premium LEO cable found with the acclaimed DUNU DaVinci IEMs.
