Pula Unicrom VS Simgot x HBB EW300 HBB

Youtube Video Summary

The PULA Unicrom delivers a warm, smooth take on a bass-boosted Harman-ish tuning, wrapped in a very comfortable, lightweight shell. Its 10 mm beryllium-plated driver proves capable, giving the low end a surprisingly tight and controlled character with weight and body that feel natural for the price. Build and fit are a clear highlight, making long sessions easy.

This is aimed at listeners who prioritize the lower-end over air and sparkle. A roughly 10 dB bass shelf adds warmth but also masks upper harmonics, so vocal presence, room cues and reverb tails are softened; the result is a more intimate soundstage and less precise imaging. Those who chase “open” treble, airy detail or gaming positional cues will likely find the upper range too polite.

At its current sale price, Unicrom is a very nice value for a relaxed, body-forward signature and a quality shell. Consider it a “teaser” for stepping up to something like Volume S in the same flavor: if the tonality clicks, the upgrade path is obvious; if not, the limitations in presence and staging will be the deciding factor.

The SIMGOT EW300 HBB Edition takes the original EW300 baseline and nudges the tuning rather than reinventing it. Subtle extra sub bass extension gives drums and electronic lines a slightly deeper thud while keeping the overall bass quick and tidy instead of thick and boomy. It still reads as a safe, mildly boosted low end that can handle R&B and hip hop, just with a bit more reach into the lowest notes.

The more obvious change is in the treble. Energy around 5 kHz and 7 kHz is lifted, which makes the upper mids and presence region more forward and shifts the perceived balance and stage compared with the original EW300. For ears that are sensitive in that area this can draw more attention to cymbals and leading edges and slightly flatten the relaxed presentation that made the stock tuning so appealing. Resolution and speed remain competitive for the price, but the overall technical step is modest rather than a clear upgrade over the standard version.

In practice this makes the EW300 HBB Edition feel like a half step away from the reference of the original: a tasteful bass tweak that many will enjoy, paired with extra treble that some listeners may find a touch too insistent. Those who loved the first EW300 and want nearly the same signature in black shells or with DSP may gravitate toward the other versions, while the HBB edition serves as the option for listeners who specifically want a bit more low end and sparkle and are not bothered by the added presence lift.

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.

Youtube Video Summary

The Pula Unicrom is a sub 100 dollar single dynamic driver set that pairs a compact resin shell and stabilized wood faceplates with a very comfortable fit and a soft modular cable that feels unusually premium for the price. Build quality and accessories feel well considered, with the lightweight shells sitting securely in the ear and the cable remaining tangle resistant and easy to handle.

Tuning follows a mild V shape that still comes across as fairly balanced, with bass sitting above neutral and leaning toward midbass emphasis that adds warmth and note weight to male vocals and instruments. There is some bass bleed into the lower mids and sub bass could be slightly more pronounced, but overall bass quality, dynamics and texture are solid for the price, and the midrange keeps decent clarity with natural timbre and lively yet controlled upper mids that give vocals good presence without crossing into shoutiness.

The treble response brings more upper treble energy than some direct competitors, adding air and micro detail while still sounding smooth and natural, which helps the Unicrom feel engaging and open. Technicalities are roughly average for the bracket, with a soundstage that is not very deep but supported by respectable layering, separation and detail that hold their own against other favorites around this price point. It may not quite reach personal benchmarks like Deli AE at the very top of the class, but it sits very close and earns a clear recommendation as a versatile budget option and a strong starting point in the hobby.

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.
