#242 Cayin Fantasy: $399.00 HiFiGo eBay

Pros: Its single 10.3mm dynamic driver at 37 ohms and 108 dB runs from a phone without strain. Listeners who want a bright, detail-forward presentation will find treble well above target, and it costs less than the equally rated Fatfreq Reference Pro SE.

Cons: Crinacle’s measurement gives it a preference score of only 61.0, and squig.link hobbyist measurements show treble about 5.5 dB hot with a 12.4 dB peak near 11.2 kHz, so cymbals and sibilance can turn harsh. Sub-bass sits about 3.8 dB below target, leaving the low end thin.
