Short answer: the FiiO FD5. It ranks #335 of 450 in-ear headphones by sound quality, rated 3.7/5, at $505.28; the Kinera Norn ranks #350, rated 3.6/5, and costs $509, which makes this an easy call rather than a real tradeoff.
The case for the FiiO FD5: Crinacle’s measurement gives it a preference score of 70, and across seven hobbyist measurements on squig.link bass rises about 4 dB above target with flat sub-bass extension to 20 Hz, giving bass guitar and kick drums a full, punchy body. The catch: The bass boost spills into the low mids by about 2 dB, which can thicken male vocals and make dense mixes sound slightly congested.
What the Kinera Norn does well: A bassy, energetic tuning with roughly 3 to 4 dB of extra sub-bass and bass, still 4.7 dB above target at 30 Hz, so electronic and hip-hop tracks hit with real rumble. The tradeoff: A 5 dB peak near 1.7 kHz in squig.link measurements pushes vocals and guitars forward, which can sound shouty on bright recordings.
Buy the FiiO FD5. It is rated higher for sound quality than the Kinera Norn and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Headphones In Full
FiiO FD5: $505.28 Amazon eBay
Pros: Crinacle’s measurement gives it a preference score of 70, and across seven hobbyist measurements on squig.link bass rises about 4 dB above target with flat sub-bass extension to 20 Hz, giving bass guitar and kick drums a full, punchy body. Its 109 dB/mW sensitivity and 32 ohm impedance mean a phone drives it easily. It rates higher than the similarly priced iBasso IT04, and the warm balance suits bass-leaning listeners.
Cons: The bass boost spills into the low mids by about 2 dB, which can thicken male vocals and make dense mixes sound slightly congested. Hobbyist measurements also show a 3.5 dB dip near 3.6 kHz and a 4.9 dB peak near 8.4 kHz, so vocals can sit a little back while cymbals and sibilants gain an edge.

Kinera Norn: $509.00 Kinera eBay
Pros: A bassy, energetic tuning with roughly 3 to 4 dB of extra sub-bass and bass, still 4.7 dB above target at 30 Hz, so electronic and hip-hop tracks hit with real rumble. The midrange and treble track the target within about 2 dB up to 10 kHz, and a 5.2 dB lift above 10 kHz adds air. A preference score of 69 from crinacle and a 2.2 dB standard deviation point to an even response overall. It matches the rating of the HIFIMAN RE2000 for noticeably less and rates above the Fearless Audio S8F.
Cons: A 5 dB peak near 1.7 kHz in squig.link measurements pushes vocals and guitars forward, which can sound shouty on bright recordings. Listeners who want a neutral low end will find the bass boost too much. The FiiO FD5 rates higher at nearly the same price.
