Short answer: the AUNE Jasper. Both are rated 4.1/5 for sound quality (#213 and #215 of 450 in-ear headphones), and the AUNE Jasper costs $239 against $254.99 for the FiiO FH5s, with sound quality a draw, the lower price decides it.
What the AUNE Jasper does well: Crinacle’s measurement gives it a preference score of 75, and across six hobbyist measurements on squig.link every band from bass to upper mids lands within 1.5 dB of target, so vocals and instruments sound natural and evenly balanced. Watch for: Sub-bass sits about 2.5 dB under target, so the deepest synth and organ notes have a little less weight than the best tunings deliver.
What the FiiO FH5s does well: Crinacle’s measurement gives it a preference score of 75, and across seven hobbyist measurements on squig.link every band from 20 Hz to 16 kHz lands within 2 dB of the Harman target. The tradeoff: A 6.6 dB peak near 8 kHz in the squig.link measurements can make cymbals and sibilant vocals sharp, followed by a 4.3 dB dip near 11.9 kHz that trims some air.
Buy the AUNE Jasper. Both are rated the same for sound quality, and it costs $15.99 less than the FiiO FH5s.

The Two Headphones In Full
AUNE Jasper: $239.00 Amazon eBay
Pros: Crinacle’s measurement gives it a preference score of 75, and across six hobbyist measurements on squig.link every band from bass to upper mids lands within 1.5 dB of target, so vocals and instruments sound natural and evenly balanced. A slight 1.5 dB bass lift adds warmth without bloat, and sub-bass stays within 6 dB of target all the way to 20 Hz. The 32 ohm, 102 dB/mW load runs comfortably from a phone or dongle.
Cons: Sub-bass sits about 2.5 dB under target, so the deepest synth and organ notes have a little less weight than the best tunings deliver. A 6.1 dB dip near 11.2 kHz in the squig.link median trims some air and shimmer from cymbals. The Shuoer S12 Pro rates nearly as high for less money.

FiiO FH5s: $254.99 Amazon AliExpress eBay
Pros: Crinacle’s measurement gives it a preference score of 75, and across seven hobbyist measurements on squig.link every band from 20 Hz to 16 kHz lands within 2 dB of the Harman target. Sub-bass stays within half a decibel of target at 30 Hz, so kick drums and synth bass hit with full weight. At 40 ohms and 106 dB/mW it runs well from a phone, and it rates above the Samsung Galaxy Buds2 and the Shuoer S12 Pro.
Cons: A 6.6 dB peak near 8 kHz in the squig.link measurements can make cymbals and sibilant vocals sharp, followed by a 4.3 dB dip near 11.9 kHz that trims some air. The AUNE Jasper matches its rating for slightly less money.
