Fiio FD5 Scorings

Average Tunign Grade

C+

Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

C-

Details smear quickly, leaving the presentation cramped and low on definition. You'll notice smearing on even moderately layered songs.

Mids C+

Expect a competent midrange that keeps vocals grounded and instruments clear. Tone is acceptable across multiple genres.

Treble C-

The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.

Dynamics C+

Dynamics feel competent, bringing energy without the finest detail. It carries energy without sounding aggressive.

Soundstage C+

You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
