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 S8Pro ranks #793, rated 3.5/5, at $489, $5.10 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the QoA Margarita: A tribrid with a dynamic driver, a balanced armature and two Sonion electrostatic tweeters. Watch for: Treble sits about 4.1 dB below target, a dark, relaxed balance.
Why pick the Fearless Audio S8Pro: Bass runs about 5 dB above target from 60 to 200 Hz in HypetheSonics’ measurement, giving a thick, punchy low end that suits listeners who like a V-shaped or warm sound. Watch for: Treble from 6 to 10 kHz sits nearly 6 dB above target with an 8.5 dB peak near 8.6 kHz, which can make cymbals and sibilance sharp and fatiguing at higher volume.
Buy the QoA Margarita. It is rated higher for sound quality, and saving $5.10 with the Fearless Audio S8Pro does not make up for the sound-quality gap.
