DUNU ITO

The DUNU ITO sounds incredible, hitting the 96th percentile for sound quality with a 2DD+2BA hybrid setup that delivers deep bass and clear vocals. But comfort is the worst we've seen at the 1st percentile, and there's no wireless option at all. Buy it for the sound, not for the convenience.

The sound here is genuinely impressive. That 96th percentile ranking isn't marketing fluff. The 10mm biocellulose driver digs deep into sub-bass territory, and the 8mm LCP driver adds punch and warmth to the mid-bass without muddying things up. The two BAs handle mid-high and ultra-high frequencies, and DUNU tuned them to avoid sibilance while keeping vocals crisp and forward. For EDM, rock, and hip-hop, this thing hits hard and stays controlled. The 5Hz to 40kHz frequency response means you're getting extension on both ends that most wireless buds can't touch.

The trade-off is that this is a passive, wired design. No ANC, no EQ app, no Bluetooth codecs to worry about. The 37Ω impedance and 105dB/mW sensitivity mean it'll run fine from a dongle or a decent DAP, but it's not going to sound its best straight out of a cheap laptop headphone jack. Total harmonic distortion is under 0.5% at 1kHz, which is solid for a hybrid at this level. The included cable is a 4-core single-crystal copper silver-plated job at 22AWG, and the Q-Lock plug system lets you swap between 3.5mm single-ended and 4.4mm balanced without buying a second cable. That's a nice touch for people who care about source pairing.

Stacked against the wireless heavyweights like the Technics EAH-AZ100, Sony WF-1000XM6, Samsung Galaxy Buds3 Pro, Bose QuietComfort Ultra, and Apple AirPods Pro 3, the DUNU ITO wins on pure sound quality and loses on basically everything else. The Technics and Sony both offer ANC, wireless convenience, and app-based EQ, but their sound doesn't touch the ITO's 96th percentile performance. The Bose QuietComfort Ultra is more comfortable by a mile, which matters when you're wearing something for hours. The AirPods Pro 3 has the ecosystem integration and mic quality that the ITO can't dream of. But none of them can match the ITO's driver configuration or frequency extension. If you want the best sound and don't care about wires, the ITO beats them all. If you want to use these on a commute or at the gym, buy literally any of the competitors instead.

Pricing on the DUNU ITO is all over the place depending on where you look. The spread across vendors is wild, ranging from around $200 to an absurd $36,604, which is almost certainly a placeholder or scalper listing gone rogue. At the $200 to $300 range, you're getting a genuinely excellent-sounding hybrid IEM with a premium cable and swappable plugs. That's competitive with other wired hybrids in this tier. But if you're seeing a price anywhere near four figures, walk away. The value proposition here is entirely dependent on finding a sane listing. The budget score of 33 out of 100 reflects that inconsistency more than the actual sound quality, which is worth every penny at the low end of that range.

The DUNU ITO lands in the 96th percentile for sound quality in our database, which is the kind of number that makes you sit up and pay attention. This is a 2DD+2BA hybrid IEM co-developed with Japanese audio YouTuber Kaji Kaji, built around a 10mm biocellulose dynamic driver for sub-bass, an 8mm LCP dynamic driver for mid-bass and vocal body, and two balanced armatures for the upper registers. The tuning goal is a live music feel, and honestly, they nailed that part. The frequency response stretches from 5Hz to 40kHz, impedance sits at 37Ω, and sensitivity is 105dB/mW, so it's not a power hog but it does appreciate a decent source.

But here's the thing. The ITO is a wired IEM in a world obsessed with wireless convenience, and the numbers outside of sound are rough. Comfort is dead last in our database at the 1st percentile, which is a real problem for something you stick in your ears. Connectivity is at the 14th percentile because, well, it's wired and that's just how it goes. Build quality is middle of the pack at the 35th percentile. If you're buying this, you're buying it for one reason: the sound. And on that front, it delivers in a big way.

If comfort is a priority for you, skip the DUNU ITO entirely. The 1st percentile comfort ranking is not a typo, and no amount of sound quality makes up for earbuds that hurt or don't stay in. If you need wireless connectivity, skip it too, because there's no Bluetooth here and the connectivity score sits at the 14th percentile. Fitness users should absolutely look elsewhere given the 9.7 out of 100 fitness score. And if you want a built-in mic for calls, the 15th percentile mic performance means you'll be reaching for something else anyway. This is a pure listening IEM for people who prioritize sound above all else and don't mind the wired life.

The DUNU ITO is a specialist's IEM. It does one thing exceptionally well, sound, and it does that better than almost everything else in our database. The 96th percentile sound ranking is backed up by a thoughtful hybrid driver setup and a tuning that makes live music genres genuinely exciting. But the comfort score is a dealbreaker for many people, and the lack of wireless connectivity means this is a desk or couch IEM, not an on-the-go companion. If you're an audiophile who wants reference-grade sound in a wired package and you're willing to deal with the fit issues, this is a strong buy at the right price. If you need something for daily carry, look elsewhere.
