#5 HIFI FOR ALL Dahlia: $999 Discontinued eBay
Pros: Tuned close to the Harman target that most listeners prefer in blind tests (preference score 95). An even response, 1.3 dB standard deviation from target, so no part of the range sticks out.
Cons: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score. Discontinued.
Is the HIFI FOR ALL Dahlia right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 95).
Skip it if
- you want more bass (about 3 dB below target).
- you need isolation or will use it in public: open-back headphones leak sound both ways.
- you want to buy it new: it is discontinued.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the HIFI FOR ALL Dahlia measures across the audible range, against the Harman over-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 audioamigo, capraaudio, gadgetrytech and superreview. Thanks to each of them for publishing their work.
