The SeeAudio Yume Ultra represents the latest evolution in SeeAudio's popular Yume series, building on the legacy of the original Yume (2021)—a breakout hybrid IEM celebrated for its smooth, vocal-forward tuning and unique liquid silicone dynamic driver—and subsequent updates like the Yume II (2022) and collaborations such as the Crinacle-tuned Yume: Midnight. As the "Ultra" trend swept the Chi-Fi scene in 2023, SeeAudio partnered with Angelears to create this refined upgrade.

The Yume Ultra aimed to address calls for a more technical, precise take on the Yume formula. It retains the 1DD + 2BA hybrid setup but features driver refinements for faster, more controlled bass, improved clarity/resolution, wider soundstage, and smoother treble extension—delivering a tactile, detailed, and non-fatiguing sound that's more modern and versatile than its predecessors. Paired with stunning shell aesthetics, a premium 6N OFC silver-plated modular cable, and ergonomic comfort, the Yume Ultra stands as a thoughtful "Ultra" edition that elevates the series' signature musicality while boosting technical performance.

Drivers: 1DD + 2BA hybrid configuration — 10mm titanium-plated diaphragm dynamic driver (for low-distortion, precise, tactile bass with strong sub-bass focus) + 2 balanced armature drivers (for clear mids and refined, extended treble)

Impedance: 12Ω (at 1kHz)

Sensitivity: 113dB ±1dB SPL/mW (at 1kHz)

Frequency Response: 20Hz–20kHz

THD (Total Harmonic Distortion): ≤2%

Noise Reduction / Isolation: ~26dB (passive)

Housing: Medical-grade resin shells with stunning 3D-printed or artistic design, ergonomic and lightweight for comfortable all-day fit

Cable: Premium detachable 6N OFC silver-plated cable, modular/interchangeable plugs (typically 2.5mm balanced, 3.5mm single-ended, 4.4mm balanced options), low microphonics, 0.78mm 2-pin connectors

"SeeAudio Yume Ultra delivers a surprisingly technical performance for its price—fast and precise bass response with excellent note separation, refined treble that's extended without harshness, and a clean, detailed overall presentation. It's shocking how well it punches above its weight class technically while keeping things musical and non-fatiguing." — Head-Fi showcase reviewer

"The Yume Ultra's treble is refined, well-extended, and flows nicely across the frequency range. Details are crisp without being too in-your-face, and the overall tonality remains pleasing and energetic. Vocals come through with good clarity and forward placement—transparent yet smooth, making it a standout for pop and vocal-heavy tracks." — Head-Fi community review excerpt

"Most importantly, the Yume Ultra maintains a highly coherent and natural timbre across drivers—quite impressive for a hybrid setup. Mids are clean and engaging with solid vocal texture and resolution, sub-bass provides tactile rumble without bleeding into the mids, and the treble adds just the right sparkle for an elegant, fatigue-free listen. It's one of the better vocal-forward hybrids in the midrange." — Head-Fi impressions thread

"The richness in vocals and instrument timbre really makes the Yume Ultra shine... sub-bass focused with quick, precise attacks, strong and forward mids that feel natural and detailed, plus a satisfyingly smooth yet extended treble section. Technically impressive, especially for the price—great resolution and separation without losing musicality." — Reddit (r/iems) user review
