#965 Forte Ears Mefisto: $2,899.00 Forte Ears $2,899.00 eBay
Pros: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap.
Cons: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones. An uneven response, 2.4 dB standard deviation from target.

Buy it if
- you are sensitive to bright or sharp treble (treble sits 3.0 dB below target).

Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $2,875 less.

Frequency Response
How the Forte Ears Mefisto 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 5 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 5 measurements from the squig.link databases of aden, dchpgall, eliseaudio, sl0the and zerostresslevel. Thanks to each of them for publishing their work.
