Youtube Video Summary
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.

Youtube Video Summary
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.
