🌀 DUNU x KOTO ITO IEM – Quad-Driver Hybrid Precision in Motion
The DUNU x KOTO ITO is a masterpiece born from a unique collaboration between DUNU, renowned for its acoustic engineering excellence, and Kaji Kaji (KOTO), Japan’s most influential headphone reviewer. Initiated by HiFiGo, this project blends KOTO’s musical vision with DUNU’s advanced tuning expertise, resulting in a sound signature that’s both bold and emotionally engaging.
After five tuning revisions and valuable feedback from audiophiles at CanJam Singapore, the DUNU x KOTO ITO delivers an immersive, genre-flexible sound that captures rhythm, clarity, and soul — all in one compact shell.
🎧 Quad-Driver Hybrid Configuration
The ITO employs a 2DD + 2BA hybrid setup for unparalleled sonic depth and detail.
-
10mm Composite Bio-Diaphragm DD – Deep, rich, and textured bass response.
-
8mm Composite LCP DD – Clean midrange with smooth transitions.
-
Dual Customized Balanced Armature Drivers – Sparkling treble and refined airiness across high frequencies.
The result is a balanced yet lively sound, perfect for genres like Rock, Hip-Hop, Jazz, and Electronic music.
🔊 Finely Tuned by Audiophile Ears
Each frequency band has been meticulously tuned to deliver:
-
Powerful low-end with natural decay and warmth.
-
Clear, articulate mids that bring vocals forward.
-
Detailed highs with excellent resolution and extension.
This tuning makes the DUNU x KOTO ITO not just an IEM, but an expression of musical artistry.
⚙️ High-Purity Cable with Q-Lock Design
Bundled with a 4-core high-purity silver-plated single-crystal copper cable, the ITO ensures ultra-clean signal transmission and sonic integrity.
It also features DUNU’s patented Q-Lock Quick Switch system, providing both 3.5mm single-ended and 4.4mm balanced terminations — making it versatile for every audiophile setup.
🎵 Premium Comfort & Accessories
The ITO comes with three types of silicone ear tips to ensure perfect fit, isolation, and comfort for long listening sessions.
💫 The Sound of Collaboration
The DUNU x KOTO ITO stands as a fusion of Japanese artistry and DUNU’s engineering brilliance — a true reflection of how passion and precision can redefine the listening experience.

Whati expected that fullfill.best iem for beginners.bass is great
Best Budget IEMS. This was my first time buying this iems and i didnt got single complaint for this. its just good for this price point
New on this IEM journey and I must say they sound better than my 3x priced headphones.
I like the sound and clarity.
Coming from Juzear Defiant and Punch Audio martilo, I would say that this is the best I have till date. Excellent in terms of clarity and technicalities. Being a medium sized IEM it is very comfortable for long listening sessions. Kudos to TAS for their excellent service.
I visited the experience store at Pune and Pritham and his asistant were very warm and welcoming. They patiently explained the pro's and con's of the Hidizs and gave me alternatives to try like the Truthear Nova and Simgot Supermix. Experiencing the different IEMS helped me maake a solid choice of what I wanted.
Also took time to sample an open back Sennheiser HD660S and the Hifiman Sundara. Was able to clearly make out the differnce betweeen a planar magnetic and DD. That helped me know what my prefernces were. Truly enlightening experience ended with a great purchase in the HIDIZS MP145.
These are my first IEMs. After a bit of research, I decided to go with the KZ Castor Pro as my first IEM. I'm really impressed with the audio depth, the crispness of audio and the clarity and separation of instruments and vocals. The music feels much different than the usual TWS earbuds which I was using before! The packaging was good, and delivery from Audio Store was good! Glad to have officially entered the IEM clan!
The Audiocular Spark DAC is amazing and it really enhances the audio quality compared to using my IEMs directly on my PC. The build is excellent, durable and it also comes with a carrying case. The packaging and delivery were both good. Really glad I bought this from here!
Unbelievable this TANCHJIM Bunny Type-C DSP whenIwas unboxed and listen immediately lheard totally theatricale experienced.It'stotally mesmerized me in sounds. In this price unbelievable soundquality. That's why this TANCHJIM Bunny Type-C DSP is more value than itsprice. Thanks once again to Pritam ji for suggestingme so wonderful IEM.
I herd of them and brought them was concerned but the audiostore team was gental and the quality of product was superior
Sound quality is very very neat and clean and in depth. Best purchase ever.
It's an amazingproductforthe price
I purchased these during christmas- and my initial impressions were that these were packaged well, and felt very premium in hand, except for the cable.
The bazz is very lacking, and the iems are unusable without tuning. After tuning these sound full, and have beautiful clarity. Definitely recommend if you can tune them. Also very good for video editors and others who need stock audio
It sounds wonderful 👍
I am very satisfied with my purchase and currently enjoying hi-res audio with my iem. Best looking and build quality is also good under 1K
This is my first IEM. I like the way it sounds. Though I expected much better soundstage but it is good. After using this, I will definitely buy my second IEM. Trust The Audio Store, they delivered as expected. Actually someone suggested me on reddit to go with audio store and I will definitely recommend others the same.
