Sony IER Z1R VS AFUL Dawn-X

AFUL’s house sound shows up here in its most polished form: Dawn-X is a tribrid (1DD + 8BA + 4EST + bone conduction) flagship at $1,300 that prioritizes consistent fit and execution over flash. Build is understated with stabilized-wood faceplates, above-average isolation, and a medium/medium-large shell that fits better—and more consistently—than the Cantor. The accessory loadout is solid (four silicone tip sets, large but well-made case), though the stock cable does not have swappable terminations (choose 3.5 mm or 4.4 mm).

Tonally, it’s a balanced, warmer-leaning take on AFUL’s signature: a dense, controlled bass that borders on decadent yet stays quick and clean, slightly relaxed mids, and a precise, mildly forward lower-treble that keeps definition high without tipping into harshness for most listeners. Stage favors front-to-back depth over width; transients are clean and a touch clinical, giving strong separation without sounding smeary. The result is a mature, confident presentation that reads refined rather than showy.

Against peers: versus Cantor, Dawn-X is warmer, smoother, and far more consistent thanks to fit; Cantor can sound brighter and a bit wider. Compared with FiiO FX17, Dawn-X has tighter bass and crisper treble, where FX17 feels looser and fuller. The 64 Audio U4s plays softer and wider; Dawn-X is more precise/clinical. DUNU Glacier hits harder and more V-shaped with smoother treble but less natural acoustic timbre; Dawn-X sounds truer on instruments. Versus ThieAudio Monarch MK4, MK4 is more neutral, vocal-forward with greater width, while Dawn-X offers denser low-end and a calmer demeanor—and a friendlier fit for many ears. Verdict: 3/5 stars—not the flashiest in its bracket, but arguably AFUL’s best execution yet of its signature sound.

Super* Review original ranking

Sony’s IER-Z1R goes full luxury flex: an over-the-top unboxing with nested boxes, a ring-case display, two stock cables (3.5 mm SE and 4.4 mm balanced), and a mountain of tips. The shells are solid metal and surprisingly heavy, feeling like they could survive a drop—or crack a desk. Driver count is “only” three, but the focus is on large dynamic drivers rather than BA stuffing; build and presentation scream premium from the first lift of the lid.

Sonically, the headline is the bass: deep, rumbly, clean, and fast, delivering both sub-bass rumble and well-separated hits—described as the best bass heard from a universal IEM. The midrange has a thicker, weighty character that plays nicer with brighter voices and pop than with male vocals or cello, which can feel a touch heavy. The treble is fit-dependent: a deep seal nets a smooth, extended top end; a shallow fit can tilt peaky and splashy—so ear anatomy and tip choice matter more than usual.

On source pairing, the IER-Z1R scales on a beefy amp but runs just fine off an Apple dongle, undermining fears that it’s a diva. As for value, the verdict is blunt: performance is stellar, but not cost-efficient; similar results can be had for half or even a quarter of the price. This set targets listeners chasing the last 10–20% of performance (or those who simply want the full Sony flagship experience), with the caveat that fit decides whether the treble sings or stings.

Sony’s IER-Z1R puts on a proper flagship show from the jump: an exquisite unboxing, hefty zirconium shells, and faceplates with a watch-grade finish that scream luxury. Sonically, the focus is the sub-bass—massive extension, physical rumble, and satisfying decay that together form a true basshead endgame. Compared to the 64 Audio U12t, the Z1R’s low end is clearly superior in slam and texture, while avoiding plasticky BA timbre; resolution is strong overall, even if the U12t keeps a slight edge in microdetail.

The tuning skews moderately V-shaped: male vocals can sound a touch hollow from a dip around the lower mids, whereas female vocals pop with presence and clarity—ideal for J-/K-pop and anime OSTs. Treble carries good extension but emphasizes stick impact that can draw attention over the air up top, a preference call more than a flaw. Staging is notable: among IEMs, the Z1R projects a “speaker-like” scale with one of the widest head-stages heard—still IEM-bound, but grander than most peers, and paired with a warm, engaging timbre.

The catch is fit and ergonomics. The shells are large and unforgiving, and for many ears comfort collapses within minutes; seal is extremely sensitive, with a poor fit turning the treble peaky around ~6 kHz. It’s the single biggest caveat: audition first rather than blind-buying. When the fit cooperates, this is a phenomenal-sounding flagship—arguably preferred over U12t for the right genres—yet its brilliance is undercut by comfort risks that will be a deal-breaker for some.

Large, sculpted shells with a bulbous rear (housing the bone conductor) make the Aful Dawn-X a substantial fit—comfortable for some, but risky for small ears. The stock cable feels quality but is 4.4 mm-only, and the case/accessories are tidy; importantly, the nozzle grips tips securely (unlike some past AFUL sets). Overall build is handsome and premium, with fit being the main variable.

Sonically, the tuning favors sub-bass over mid-bass, pairs rich mids with smooth, natural treble that avoids harsh spikes yet has mild 4–6 kHz energy, and presents a cohesive, almost speaker-like soundstage. It wakes up with a bit of volume/power, prioritizing clarity, micro-detail and air over outright slam; the bone conductor subtly supports the midrange more than the lows. At $1,300 it’s competitive for listeners chasing technical refinement and a natural tonality, while value seekers or mid-bass lovers may prefer cheaper AFUL options or sets with more punch.
