Short answer: the Cayin Fantasy. It ranks #395 of 450 in-ear headphones by sound quality, rated 3.0/5, at $399; the Jabra Evolve 75e ranks #410, rated 2.7/5, and costs $399.95, which makes this an easy call rather than a real tradeoff.
The case for the Cayin Fantasy: Its single 10.3mm dynamic driver at 37 ohms and 108 dB runs from a phone without strain. Watch for: 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.
The case for the Jabra Evolve 75e: It brings wireless convenience with active noise cancelling, a built in microphone for calls, 14 hours of claimed battery life and IP54 resistance to sweat and splashes. The catch: In oratory1990’s measurement a 15.9 dB peak near 10.7 kHz and air about 10 dB above target make cymbals, hi hats and sibilance harsh and fatiguing.
Buy the Cayin Fantasy. It is rated higher for sound quality than the Jabra Evolve 75e and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
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.

Jabra Evolve 75e: $399.95 Wireless Amazon eBay
Pros: It brings wireless convenience with active noise cancelling, a built in microphone for calls, 14 hours of claimed battery life and IP54 resistance to sweat and splashes. Bass is boosted about 6 dB above the Harman target down to 20 Hz, which suits bassy and V shaped listening tastes.
Cons: In oratory1990’s measurement a 15.9 dB peak near 10.7 kHz and air about 10 dB above target make cymbals, hi hats and sibilance harsh and fatiguing. Bluetooth 4.2 is an older version, and the Etymotic ER4XR rates higher for less money.
