#508 DDHiFi E13P Memory: $169.99 Linsoul $169.99 eBay
Pros: A semi in-ear 13mm planar earphone with a built-in USB-C DAC and inline remote. It measures reasonably close to the Harman target (score 71 across four measurements).
Cons: Treble sits about 4.7 dB below target, a dark, relaxed balance. Bass sits about 2.2 dB below target, so it sounds lean. Sub-bass falls about 3.8 dB short at 30 Hz. The USB-C plug only works with sources that output digital audio over USB.
Is the DDHiFi E13P Memory right for you?
Buy it if
- your taste runs warm: it scores 81 for that sound.
- you are sensitive to bright or sharp treble (treble sits 4.7 dB below target).
Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $146 less.

Frequency Response
How the DDHiFi E13P Memory 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, arn, audioamigo and tonedeafmonk. Thanks to each of them for publishing their work.
