The Heartfield CU8 delivers a neutral sound that closely follows the Harman target curve, providing a balanced and accurate listening experience suitable for both critical monitoring and musical enjoyment. Its bass response is tight and textured, with a slight mid-bass bump that adds a touch of warmth without bleeding into the mids, while the treble remains smooth and free of sibilance.
Build quality is a standout, featuring a hand-finished brass chamber that feels premium but contributes to a heavier design, which might affect fit for some users during extended wear. The included cable is thin relative to the IEM's weight, though the deep recessed 2-pin connectors ensure a secure connection.
Overall, the CU8 excels with a natural timbre and cohesive presentation, making it a strong choice for those seeking an analytical yet engaging signature across genres, though its weight and sparse accessories are minor drawbacks. The PUR vibration control system effectively enhances dynamics, allowing its four balanced armatures to perform with the impact of more complex driver setups.

The MYER SLIIVO SL224 is an eight-driver hybrid built around 2DD+2BA+4 micro-planar units with a 36 Ω impedance and 108 dB sensitivity, positioned at an MSRP around $269.99 (often on sale near $230). This configuration, including 10 mm and 6 mm dynamic drivers, suggests an intent toward a clean, extended response rather than a bass-dominant tuning. Specs & pricing: 2DD+2BA+4 micro-planar, 10 mm + 6 mm DD, swappable 3.5/4.4/Type-C cable, sale price ~$229.49, regular $269.99.
Subjective reports converge on a balanced/neutral tonality with energetic yet controlled low end from the dual-DD array, lively mids, and an airy but not piercing treble. Mobileaudiophile characterizes bass as fast and powerful with engaging mids and treble, yielding a coherent, never-boring balance; this aligns with the SL224’s technical focus rather than coloration. Tonality & balance references: balanced tuning, lively mids, airy treble; bass praised for speed and control.
Technical impressions emphasize dynamics, detail retrieval, and cleanliness, with community notes calling out tight, quick mid-bass and respectable separation; limitations include occasional midrange forwardness that can mask other bands on some tracks and a stage that reads more precise than expansive. These traits point to strong value in the ~$230 bracket for listeners prioritizing clarity and midrange presence over sheer sub-bass weight. Community impressions & caveats: tight mid-bass, good dynamics; mids can get a bit forward depending on material.

Youtube Video Summary
The MYER SL224 is a stylish tribrid (2DD + 2BA + 4 microplanars) coming in around $270, shipped with a decent 4-core cable featuring 3.5 / 4.4 / USB-C interchangeable plugs, a zipper case, and three ear-tip sets (regular silicone, SpinFit-style silicone, foam). Build is eye-catching thanks to a real mother-of-pearl faceplate; the shell is on the larger side with a universal-custom shape that sits comfortably for long sessions, though smaller ears should test fit first. Cable behavior is mostly cooperative (functional chin slider, slight memory), and overall accessories feel thoughtful for the price.
Tonally, SL224 targets a clean, clinical presentation: sub-bass carries the weight while mid-bass stays nearer to neutral, which can read a touch lean unless paired with a warmer source (tube or similar) to add body. The midrange tracks neutral until the upper-mid / lower-treble rise, boosting female vocal harmonics and air; some may find this area forward, yet it avoids the usual micro-planar harshness. Treble is well-extended and energetic, if not the smoothest—there’s a hint of disconnect around the pinna gain—but this nit shows mainly against sets two to three times the price. Technical chops are a highlight: resolution rivals class standouts (think AFUL P7 territory), imaging is tidy, stage is fairly wide, and it earns a strong nod for competitive gaming.
Against peers, CK2V hits harder down low but dips mid-bass and feels less even up top; AFUL P7 is more balanced yet less flattering to female vocals and trickier in treble; “Dusk” (DSP) delivers better bass and a warmer tilt; “Brain Dance” is flashier but far sharper; Moondrop Meteor tracks a similar tonality with smoother highs and a mid-centric lean—an easy upgrade path if this signature clicks. Recommendation is clear: pick SL224 for a mid/treble-focused set with standout detail and clarity; skip it if sensitive to upper-mid energy or chasing a warm, bass-rich tuning. For value, this feels underrated and distinct in a meta-heavy market, earning a solid three-star recommendation.

Youtube Video Summary
Packaging overdelivers: a modular cable with 3.5/4.4/USB-C and an included dongle that gets loud enough, seven pairs of silicone tips plus foam, and a small zip case (nice but tight). The shell looks premium with a depth-effect faceplate and a metal nozzle (≈6.1 mm lip); fit is snug though potentially big for smaller ears. Build and accessories feel thoughtful at the price, with only a slightly rubbery cable texture to nitpick.
Tuning is a smooth, vocal-focused, meta-inspired balance: refined mids, a friendly yet detailed top end, and a clean, controlled low end. Bass quality is textured and separated but intentionally polite—not for hip-hop/EDM impact chasers. The midrange brings clear, natural tone without shout; both male and female vocals sit forward. The treble is the star: highly resolving, airy, and surprisingly non-fatiguing for the four micro-planars, avoiding metallic glare while adding tasteful sparkle.
Technically, separation and resolution impress, with a mild cohesiveness quirk where the treble detail outshines bass/mids. Versus peers: CK2V is more V-shaped and brighter-hot; SL224 sounds more natural. Moondrop Meteor offers smoother treble and mid timbre, but SL224’s bass quality and value punch back. Dunu Brain Dance is technically stronger; SL224 wins on tonality. SoftEars Studio 4 remains more lifelike/cohesive; SL224 brings more air and fun. AFUL Performer 7 is the better all-rounder; SL224 is for lighter-bass, vocal clarity. Kiwi Ears Astral is airier/more micro-detailed; SL224 plays it safer up top with more forward vocals. Recommendation: vocal lovers and treble-sensitive listeners wanting detail without sting. Not for bassheads or warm-tilted tastes. Final verdict: a confident 4/5 and the most compelling Myer release so far.
