Pros: True wireless earbuds with a dynamic driver and two Knowles balanced armatures per side, an AKM DAC and aptX Adaptive. Measurements show treble right on the Harman target and full sub-bass to 20 Hz (score 73 across four measurements).
Cons: A 1.95 dB spread from the target still leaves some peaks and dips.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the FiiO FW5 measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the median of 4 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 4 measurements from the squig.link databases of aftersound, iemocean, superreview and vsg. Thanks to each of them for publishing their work.
