DUNU x KOTO ITO Hybrid In-Ear Monitors
The DUNU x KOTO ITO is a collaborative hybrid in-ear monitor developed by DUNU in partnership with Japanese audio reviewer Kaji Kaji (KOTO). Designed through multiple tuning revisions and real-world feedback, it delivers a rhythmic, full-bodied sound signature with strong bass impact, clean midrange presence, and extended treble detail, making it well-suited for rock, hip-hop, electronic, and other rhythm-driven genres.
2DD + 2BA Hybrid Driver Configuration
Each earpiece houses a four-driver hybrid setup consisting of two dynamic drivers and two balanced armature drivers. A 10mm composite bio-diaphragm dynamic driver handles deep sub-bass response, while an 8mm composite LCP diaphragm dynamic driver covers the mid-bass and midrange frequencies. Two custom balanced armature drivers manage the high and ultra-high frequencies, providing clarity and extension without harshness.
Bass-Focused Yet Balanced Tuning
The ITO is tuned for impactful low-end performance with controlled punch and natural midrange clarity. The dual dynamic drivers produce deep, textured bass with strong rhythmic drive, while the midrange remains articulate and present so vocals and instruments stay clear even in bass-heavy tracks. Treble is smooth and sufficiently extended to add air and detail without fatigue.
Lightweight Resin Construction and Comfortable Fit
The shells are crafted from high-quality resin and weigh approximately 6.5g per side. The ergonomic design prioritizes long-term comfort and passive isolation, allowing extended listening sessions with a secure and stable fit for most ear shapes.
Modular Cable with Q-Lock System
The ITO comes with a high-quality detachable cable featuring DUNU’s Q-Lock quick-switch system. Users can easily swap between the included 3.5mm single-ended and 4.4mm balanced plugs without tools, offering flexible connectivity for a wide range of sources and amplifiers. The cable uses a standard 0.78mm 2-pin connector for easy upgrades.
Premium Accessories Package
The package includes multiple pairs of high-quality silicone eartips in different styles to suit various preferences for seal, comfort, and sound balance, along with a protective carrying case and the modular cable system.
