#12 Sonicast Direm E3: $85.18 Amazon $85.18 eBay
Pros: A single dynamic driver earphone at about $85 with a preference score of 86 and an exceptionally low 1.04 dB deviation from target. Sub bass, bass, mids and presence all sit within about 1 dB, so the tuning is natural across genres, and it has an inline microphone.
Cons: Air above 8 kHz is about 2.7 dB low with a 6.4 dB dip near 11.2 kHz, so cymbals have slightly less shimmer. Sensitivity is a modest 103 dB/mW, and the score rests on a single measurement.
Is the Sonicast Direm E3 right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 86).
- you want sub-bass rumble that reaches down to 20 Hz.

Frequency Response
How the Sonicast Direm E3 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 a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of silicagel. Thanks to them for publishing their work.
