Refines the original Timeless into a more approachable planar with four tuning nozzles; Silver Bullet favored for forward mids and clarity. Not as balanced as S12 2024 out of the box but offers flexibility and strong detail. Four swappable nozzles provide distinct tunings and make the set widely approachable. Upper-treble air and stage height can feel constrained unless foam/nozzles are tweaked.
Youtube Video Summary

Timeless II modernizes the original’s high-detail character into a more approachable package. The headline is four tuning nozzles (Gold Flower, Silver Flower, Gold Bullet, Silver Bullet) that meaningfully shift presence/upper mids and treble, letting listeners choose between a relaxed, natural profile and a forward, planar-typical clarity. Build quality, modular cable and accessories are polished, fit is comfortable, and the overall aim is to give newcomers an easy entry into planar detail without the harsher edges.

With the Silver Bullet, vocals move forward with crisp articulation and strong resolve; the bass shelf sits near Timeless AE levels with clean definition, while treble is consciously smoothed to reduce planar sharpness and sibilance. The Flower filters sound more relaxed and dynamic-driver-like but give up some nuance and air. Out of the box it is not as perfectly balanced as the S12 2024 reference, yet the nozzle/foam system provides real tuning flexibility: small foam changes can restore upper-treble air and add stage height, making Timeless II a versatile, top-tier option at its price.

Misty Blue is a refined, under the radar hybrid around 220 USD, with smooth early rise tuning, rich mids and extended yet controlled treble that create a natural, cohesive listen. It trades sheer slam and brightness for balance and maturity, suiting listeners who value mids and refinement over explosive excitement. Refined early rise tuning with controlled bass, clear mids, extended yet smooth treble and surprisingly strong staging and imaging for a hybrid around 220 USD. Not very high on engagement, with polite bass impact and a mid focused, slightly neutral presentation that some listeners may find too relaxed or even a bit boring compared to more energetic sets.
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 7Hz Timeless II updates its predecessor with a 14.5mm planar magnetic driver featuring a dual-sided silver alloy diaphragm and N52 magnets, offering improved responsiveness and reduced "planar timbre" compared to the original . Its standout feature is the four interchangeable nozzles, allowing tonal adjustments—though the bullet-shaped variants suffer from condensation issues and noticeably reduce treble clarity . Comfort is decent for medium-to-large ears, but the aluminum shells may challenge smaller anatomies, and isolation remains average despite a secure fit .

Tonally, the Timeless II leans neutral with a sub-bass lift, delivering fast, textured lows that avoid bleeding into the mids . Midrange clarity is strong but can edge into harshness with upper-mid-forward tracks, while treble extends well without excessive sibilance . Technically, it excels in imaging precision and soundstage width, though depth and height feel constrained next to hybrids like the Simgot ET142 .

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.

Youtube Video Summary

Timeless 2 shows up with a bigger, round shell (carbon-fiber face, metal rim), a nice hard case, and an oddball-but-cool ribbon cable on MMCX that feels a bit stiff. The real headline is the swappable nozzles: tiny side-vent “pin” nozzles (stock), a “flower” top-vent nozzle, and a large side-vent set. Tip pack is a colorful grab bag (no foams), and care is needed because narrow bores can block those side vents. Power isn’t a problem—this set is very efficient and plays happily from a phone or desktop amps without turning harsh.

Sonically, the three nozzles behave like three different tunings. The stock tiny side-vents are wide, chill, and distant—easy listening with big space. Swap to the “flower” top-vent and everything snaps into focus: detail rockets up, staging comes closer, and transients clean up without tipping into sibilance; bass also tightens and gains punch. The big side-vent option brings more bass weight and a huge stage, trading a bit of hyper-detail for scale and fun. Tip rolling matters: wide-bore silicone (e.g., Dunu SS) or high-seal foams can make it a party in the head, while tight-bore foams can choke the vents and thin the sound.

With the right nozzle/tip combo, Timeless 2 goes from “good planar” to aggressively engaging: thunderous taiko hits, breathing and string texture on acoustic tracks, and club-ready energy on electronic. It feels like the most complete planar IEM here—big soundstage, real bass presence, and crisp clarity that invites louder listening. If pricing sits around the speculated $260–$320 range, this could muscle aside a lot of sets under $500–$600. Verdict: a bold, successful experiment that delivers three flavors of planar goodness, with the “flower” nozzle as the standout for clarity + slam.

Good all-rounder set with solid tech. Good variety with the nozzles that actually changes the sound. Treble is smoother than other planars, and not much "planar timbre".
Youtube Video Summary

7Hz Timeless 2 arrives as a polished successor to the original, delivering a smoother, more refined treble and a presentation that feels less “planar” in timbre. Its headline feature is the interchangeable nozzle system that meaningfully changes the sound—three distinct tunings rather than subtle tweaks—so fit and flavor are easier to dial in. Technicals remain solid for the class (layering, separation, staging), but the emphasis shifts from raw edge to easy, airy listenability; compared to brighter, snappier planars, this one trades a touch of bite for balance and comfort. Pairing with regular Sedna-style tips further smooths the top end without dulling it.

Midrange is handled with a calmer 2 kHz region, so vocals sound less forward and less shouty on energetic tracks. The silver nozzle tames that zone even more, appealing to listeners who prefer flatter upper-mids while adding a sense of openness and clarity. Bass is punchy, quick, and clean with good impact that avoids bleed; it won’t out-slam a strong dynamic-driver set, but the planar low-end here feels tight and versatile, fitting an all-rounder profile. If ultra-etched detail and hyper-tactile treble are the goal, some rivals push further; if the priority is smoothness without boredom, Timeless 2 hits the brief.

As a value play, sub-$100 options still undercut it, yet the combination of refinement + three nozzles makes Timeless 2 competitive at its price. Owners of recent planars may find it a side-grade in sheer technicals, but for anyone starting fresh—or seeking a safer, fuller tuning that scales reasonably—this is a confident recommendation. Use the smoothing tips and select the nozzle that fits the library, and it becomes a comfortable daily driver for most listeners.
