This and That:
Two dynamic drivers and two Balanced Armatures per side.
Cardboard packaging doesn't appear premium at all while its slipcase wrapper is rather decent.
Comes with many accessories and tips but not nearly as many as the DN-2000J.
I really like the storage case - sturdy, light, spacious and cushioned on all sides on the inside. Seems like a copy of the Pelican cases, although at lesser quality.
Unique shell design, somewhat like an homage to Audio Technica's old models. Combines high quality plastic with metal parts. Doesn't look or feel as premium as DUNU's other pricier products.
Only the DUNU logos could have been made differently (they appear to be printed).
Locked MMCX, so it should drastically reduce wear on the connectors.
Cable just as fantastic as that of the DN-2000J - one of, if not the best non-twisted cables around along with that of the Jays q-JAYS (the newer ones with removable cables). Super flexible and supple. Air canals inside the cables above the y-splitter to make them more durable when they are squeezed or bent.
Nice touch: the white silicone tips are branded with the DUNU logo.
Sound:
Largest included white silicone tips, low impedance sources.
Tonality:
What sort of sucks (but is absolutely normal for dynamic drivers, as it's an important factor for their (sub-) bass tuning) is that the DN-2002 will have an either rolled-off or emphasised (sub-) bass, depending on how much the dynamic drivers' front cavity vent is blocked (which happens naturally in one's ears).
With a fully open vent, the sub- and midbass will extend poorly and be below neutral in quantity, with a hump whose climax is in the fundamental range around 300 Hz.
If the vent is fully blocked though, the sub- and midbass with be strongly elevated, with a climax at 20 Hz with an emphasis of ca. 10 dB compared to diffuse-field flatness.
And then there's a lot of variance in-between. Ideally with a somewhat-but-not-fully-blocked vent, the lowest sub-bass will be just neutral in presence, align with the central mids, with a roll-off that starts at 60 Hz and with a hump that has its strongest quantity (ca. 5 dB compared to diffuse-field flatness) between about 60 and 200 Hz, and becomes neutral again at 20 and around 800 Hz.
So yeah, ideally the (mainly upper) bass will be 5 to 10 dB above diffuse-field neutrality, else the sub-bass is below-neutral in quantity.
The fundamental range is lifted and full sounding, and radiates into the lower mids that are warm.
The upper mids above 1.5 kHz are on the darker, relaxed side, along with the middle highs that are in the background, too.
Generally, the treble is dark and relaxed in the lower and middle highs, and comes back in the upper treble with a broad elevation between 7.5 and 10 kHz that's about 4 dB north of neutral.
Super treble extension past 10 kHz is good and goes past 16 kHz.

It's a dense, warm, dark sounding in-ear with some upper treble brightness. And I hate the front cavity vent.
Resolution:
Resolves well and mostly adopts the DN-2000J's resolution. Sounds somewhat muffled due to the tuning, though. It's really just the tuning and not the actual resolution, nonetheless.
Highly controlled bass. Good balance between speed and dynamic driver softness (body). Slightly quicker decay than on the DN-2000J. Therefore tactile/visceral bass presentation.
Clean note separation and good micro detail retrieval but lacks a bot of presence/shimmer due to the reserved upper midrange/presence range.
Soundstage:
Large, open stage (expands audibly further than the base of my head) with really clean and precise separation, layering and imaging.
Identical to the DN-2000J's stage to my ears.
Conclusion:
Warmth in the lows coupled with dark lower and middle highs and some upper treble brightness counterweight. Could use somewhat less upper midrange/presence range relaxation to truly shine. Technically capable; nice soundstage. Welcome alternative to most of DUNU's other usually bright treble hybrid in-ears.
