#995 Penon Impact: $2,499.00 Penon Audio $2,499.00 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 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones. An uneven response, 2.9 dB standard deviation from target.
Is the Penon Impact right for you?
Buy it if
- you are sensitive to bright or sharp treble (treble sits 5.0 dB below target).
- you want sub-bass rumble that reaches down to 20 Hz.
- you are happy to use EQ: our preset lifts its Harman match by about 16 points.
Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $2,475 less.

Frequency Response
How the Penon Impact 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 ducbloke, eliseaudio, tgx78 and tonedeafmonk. Thanks to each of them for publishing their work.
