Youtube Video Summary
Misty Blue from Queen of Audio and Eir Aoi presents as a very polished hybrid in the low two hundred dollar range, wrapped in a deep blue visual theme with a resin shell, modular blue cable and generous accessories. The tuning follows an early rise, low ear gain approach that feels more like an expensive custom style than a shouty Harman clone, with a bass shelf that supports a very linear, extended treble rather than trying to dominate the signature. Overall the set comes across as an under the radar collaboration aimed at listeners who prefer balance and refinement over raw impact.
On the low end, Misty Blue uses its dual dynamic drivers to build a tight, taut bass shelf that gives full sub bass and mid bass presence without boom or bloat, acting as a foundation rather than a spotlight. That smooth shelf flows into natural mids with a touch of BA edge, yielding clear vocals and a rich, resonant lower midrange that sounds deeper and more refined than many contrast heavy hybrids that dip the middle while boosting both ends. Treble looks peaky on paper, but in practice remains controlled and non fatiguing, offering plenty of extension and a subtle hybrid bite without tipping into metallic glare, which keeps the overall tonality slightly neutral and very coherent from bass through upper treble.
In technical terms this hybrid stays fast, layered and clean, with the careful level control and extended treble helping notes separate and decay naturally while the fuller low end prevents thinness. Stage and imaging performance are notably strong for the price, producing a more 3D sense of space than expected and occasional moments where instruments appear clearly above and off to the side, supported by solid detail retrieval and overall control. The trade off is that the presentation is not especially high in visceral engagement or bass forward drama, so Misty Blue is best suited to mids focused listeners who value natural tonality, balance and a more mature, advanced style of tuning that would not feel out of place on more expensive hybrids.

The Queen of Audio x Eir Aoi Misty Blue is a collaboration IEM built around a hybrid 2DD+2BA configuration with a 10 mm bass driver, 8 mm mid driver and dual BAs handling upper mids and treble, plus interchangeable 3.5 mm and 4.4 mm terminations and even a bundled USB-C dongle for phones. The hand-finished resin shells and Eir Aoi-themed faceplates position it as a collectible piece as much as an everyday tool, with pricing generally sitting in the ~US$220–270 range depending on retailer and region. Vendor descriptions and user impressions consistently note a light, contoured fit with good passive isolation, helped by the relatively compact shell and multiple tip sets.
In terms of tuning, Misty Blue aims for a balanced, mildly U-shaped signature: bass has some warmth and weight from the dedicated low-frequency dynamic, but it is described as not bleeding into the mids, which stay natural and clear, while the BA drivers add air and extension up top. Early community feedback characterises it as warm, pleasant and mature rather than aggressively V-shaped, which suits vocal-centric J-pop and rock material associated with Eir Aoi’s catalogue. Some listeners note that while overall tonality is cohesive, certain instruments can feel slightly short of “ultra-resolving”, hinting that tuning quality slightly outpaces raw microdetail at this price.
Technical performance is respectable for the segment: a short comparison video reports improved sub-bass reach, upper-treble presence and imaging over another QoA model, suggesting solid staging and positional cues even if overall resolution is more mid-tier than benchmark-setting. The included USB-C dongle, using a Realtek DAC, is generally regarded as usable but sonically bland and power-limited, with owners recommending a better source to unlock the IEM’s dynamics and separation. Considering the strong accessory set, artistic design and well-judged warm-balanced tuning against only moderate detail retrieval and a slightly elevated street price, Misty Blue represents a solid but not class-dominating value in the ~US$220 bracket, appealing most to listeners prioritising tonality and aesthetics over maximum technical performance.
