Short answer: the Fearless Audio S8F. It ranks #780 of 1369 in-ear headphones by sound quality, rated 3.5/5, at $489; the GoldPlanar GL-AMT16 ranks #863, rated 3.4/5, and costs $1,499, which makes this an easy call rather than a real tradeoff.
What the Fearless Audio S8F does well: Crinacle’s measurement gives it a preference score of 68, a moderate match to the response most listeners prefer. Watch for: A 2.5 dB standard deviation from target points to an uneven response.
What the GoldPlanar GL-AMT16 does well: A broadly balanced tuning with a preference score of 67 against the Harman target. Watch for: About 3 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music.
Buy the Fearless Audio S8F. It is rated higher for sound quality than the GoldPlanar GL-AMT16 and costs less, which makes it the one to get unless you need something the other one does better.
