Sound classification
Representative listening character
Weight, impact and rhythmic energy are the main listening attractions. This editorial browsing category is drawn from retained model-specific reviews; it does not exclude other listening uses.
Similar listening character ↗Frequency emphasis: Bass emphasis. Strong impact, firm bass and an open presentation are supported by cafe owners. Initial overload and later comfort were reported under changing output, tip and source conditions. Overall timbre: Warm tone. These are separate representative axes; fit, nozzle settings and contrary accounts remain in the reviewed evidence.
Differences by listening conditions: Sharp guitars and strong treble occur for some owners; fit, source and adaptation are uncontrolled, and upper extension can be limited.
Concise English summaries distinguish product specifications, reviewed listening impressions and practical advice. Original source notes remain available below.
Bass quantity and texture
Strong impact, firm bass and an open presentation are supported by cafe owners. Initial overload and later comfort were reported under changing output, tip and source conditions.
Vocal placement and midrange
Full lower mids and forward upper mids.
Treble and fatigue
An owner reports very sharp initial guitars, later less fatigue; another finds source-dependent treble intensity. Neither account isolates physical burn-in or cable material as the cause.
Stage, separation and imaging
Strong placement, with conflicting reports of width.
Disagreement and listening conditions
The bass, vocal and treble descriptions summarise reviewed impressions, not measured quality. Tips, volume, nozzle settings and source conditions can explain differences. Sample relationships and duplicate authors remain disclosed in the source records.
Strengths and caveats from reviewed sources
Supplementary notes retain the original Korean research wording.
Dunu Zen Review – Zenith ↗ — Warm, full mids with upper-mid and lower-treble emphasis and rolled-off upper treble. Bass texture, impact and both small- and large-scale dynamics were strongly praised. Depth, height and placement were positive, but width was narrow and intimate. Tips and insertion depth were reported to strongly affect treble intensity and separation.
Dunu ZEN 청음기 - 선입견 깨기 ↗ — Original ZEN. The reviewer described moderately full bass, slightly rough yet open highs, suitable vocal placement, fast impact and broad, deep space. ORB and Brise cables differed from stock conditions. Reports elsewhere of excessive bass and recessed vocals did not match this listener's experience.
Listening suggestions and selection points
Start with rhythm-driven electronic music, hip-hop or rock. Compare the satisfaction of kick and bass impact with how much room remains for voices as bass notes overlap.
These are editorial starting points derived from the existing sound descriptions, not results of a genre-by-genre test. Recordings and arrangements vary even within one genre.

With these two, I’m done with iems (for now at least)
Original Zen with a Rhapsodio Golden Mk4 cable. Jazz and female vocals were strongly praised, while limited upper-treble extension led the owner to use Holocene for heavy metal and electronic music. No causal cable-material claim was established; physical cable praise is excluded from tonal evidence.
Personally purchased a store demo unit.

Original ZEN with R5 Saber or iPhone 7/Q3, the stock 4.4 mm cable and foam tips. The owner heard fast, clear mids and highs, close vocals and little harshness. Bass changes cannot be attributed to burn-in because tips and usage time changed together.

Dr. Headphone — One month with DUNU ZEN
After a month the owner praised tight, strong impact, a fast open sound and a wide stage. Early rough guitars and recessed vocals were tiring; later vocals seemed clearer and treble less sharp. This reports a change in experience, not an isolated cause.
Second-hand purchase through a marketplace stated; supply or advertising relationship not specified.
The usage report was read directly after an internal community search. Second-hand purchase and one month of use; Galaxy S21 Ultra with iFi hip-dac, PowerMatch on, 4.4 mm. Mainly rock and metal, with pop and Korean songs. The listener stated that the 3.5/4.4 mm output difference was initially overlooked.
