#653 Sony IER-EX15C: $28.00 Amazon $28.00 eBay
Pros: At 3 g per earpiece it is very light, and the built-in microphone makes it handy for calls. Across two hobbyist measurements on squig.link it scores 62.2 for Harman preference, with a mild bass and low mids lift of about 2 dB that gives a warm, relaxed tone. Its peaks stay small, the largest only about 2 dB near 9.7 kHz, so treble never turns harsh.
Cons: Sub-bass rolls off about 2.8 dB below target under 60 Hz, so deep synth bass and rumble are subdued. A presence dip of about 4.7 dB in the 3 to 6 kHz range, reaching 5.4 dB near 4.8 kHz, makes vocals and instruments sound veiled and less clear. The KBEAR Storm rates higher and costs less.
