Pula Unicrom VS EarAcoustic STA Pro Max

Youtube Video Summary

The Pula Unicrom offers a comfortable and well-built shell with clear left/right indicators and a swappable cable featuring a secure 4.4mm connector. It comes in four colors and includes a highly praised magnetic case considered excellent value. The cable itself is noted as one of the nicer options at this price point, though the lack of a USB-C option is a minor drawback.

Sonically, the Unicrom delivers a smooth, slightly bassy, and darkish signature with visceral, thick bass and rich, thick mids. Its upper mids are nice and not overly shouty or sibilant, resulting in a cohesive dynamic driver sound. While it lacks the absolute best detail, imaging, and air, it provides a fun and engaging listen, described as a strong V-shape. Graph comparisons show it shares similarities with the much more expensive Moondrop Dragon and the RT10 Pro, offering that kind of tonality at a significantly lower price. It faces stiff competition around $100, like the RT10 Pro and Letshuoer S08, but holds its own as a competent, colorized option.

Ultimately rated a solid B minus, the Unicrom earns a value star and a strong recommendation as a great all-rounder under $100. It's highlighted as a beautifully executed product with satisfying, rich mids and bass, making it a compelling choice for those seeking an organic, fun sound, especially as a gift. While the lower mid warmth might not suit everyone and detail seekers might prefer sets like the Hexa, the Unicrom stands out as a unique and interesting bassy dynamic driver option at its price.

At $80, the Pula Unicrom (aka “Unic”) is a 10 mm single dynamic IEM that keeps the box basic but surprises with a genuinely nice cable—tight weave, slick hardware, and a stealthy screw-on plug that feels finely machined. The shell finishes can be oddball, the naming is weirder, but in the ears it’s easy to drive and hassle-free; throw on preferred tips and it’s ready to go. Marketing quirks aside, build and usability punch well above the bracket.

Sound is the headline: a wide, relaxed soundstage that floats instruments around the head with real dynamics—swells hit hard, decays fall away cleanly, no shout or sting. Bass is warm and textured without bloat, mids stay clear and focused, and treble sprinkles detail instead of poking holes; it’s the rare “fixer IEM” that flatters rough recordings yet makes orchestral and soundtrack cues feel big. For the money it’s a no-brainer—fun, forgiving, cohesive—proof that a well-tuned single DD can still embarrass busier driver packs in this range.

Youtube Video Summary

STA Pro keeps the dual dynamic recipe but swaps to 10 mm + 6 mm composite diaphragms instead of the Pro Max's LCP and titanium-plated combo. Build is similarly solid—arguably flashier on the faceplate—yet the driver change shifts the character in ways that don't mirror the Max.

While the bass shelf remains, the Pro adds more upper mids and a touch more treble, pulling focus from the low end and dulling the TFZ-style, big-bass fun that made the Max engaging. The attempt to "poke in" extra presence for detail doesn't convert into true clarity; the balance turns brighter and less relaxed.

Technicalities trail the Max: less resolution, less perceived detail, and it doesn't volume scale the same way, coming across as a more affordable, less refined variant. For this line, the smarter buy remains the STA Pro Max with the LCP + titanium drivers; the base STA Pro simply doesn't reach the same level.
