Moondrop Chu Scorings

Average Tunign Grade

C+

Generally enjoyable tonal character with some noticeable unevenness. Maintains listenability while showing room for refinement in frequency balance.

Average Technical Grade

Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Bass C-

Subdued bass response that stays mostly in the background. Lacks energy and impact but maintains basic definition.

Mids B-

Decent midrange performance - balanced but unremarkable. Adequate clarity for most genres without notable flaws.

Treble C+

Decent treble with acceptable extension and detail. Can sound slightly unrefined but avoids being harsh or sibilant.

Dynamics D

Noticeably compressed dynamics. Musical expression suffers with weak transients and poor contrast between quiet and loud sections.

Soundstage C+

Decent spatial presentation with noticeable width. Some depth perception but height dimension remains underdeveloped.

Details C-

Average resolution - reveals basic elements but misses subtleties. Satisfactory for casual listening but lacks refinement.

Imaging C-

Average imaging - reasonable localization but lacks specificity. Instruments have general positions but lack pinpoint accuracy.

Gaming C

Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

Beaten by Salnotes Zero for my library. Good tuning, medriocre techs, but throwing punches up to 100$. Hard to fault. Cable is bad but workable.
