Short answer: the QoA Margarita. It ranks #731 of 1291 in-ear headphones by sound quality, rated 3.6/5, at $494.10. The Fearless Audio S8F ranks #779, rated 3.5/5, at $489, $5.10 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the QoA Margarita does well: A tribrid with a dynamic driver, a balanced armature and two Sonion electrostatic tweeters. The tradeoff: Treble sits about 4.1 dB below target, a dark, relaxed balance.
Why pick the Fearless Audio S8F: Crinacle’s measurement gives it a preference score of 68, a moderate match to the response most listeners prefer. The tradeoff: A 2.5 dB standard deviation from target points to an uneven response.
Buy the QoA Margarita. It is rated higher for sound quality, and saving $5.10 with the Fearless Audio S8F does not make up for the sound-quality gap.
