Short answer: the Oriolus Isabellae. It ranks #217 of 450 in-ear headphones by sound quality, rated 4.1/5, at $600. The Hisenior Mega5EST 7th Anniversary Edition ranks #249, rated 4.0/5, at $549, $51 cheaper, which does not close the gap in sound quality.
The case for the Oriolus Isabellae: A single 9.8mm dynamic driver earns a preference score of 75 from crinacle, and squig.link measurements show a 3.2 dB upper bass lift that gives a warm, punchy foundation without bloating the mids. Watch for: Across hobbyist measurements a 7 dB peak near 11.2 kHz adds sparkle that can tip into sibilance or splash on bright recordings.
Buy the Oriolus Isabellae. It is rated higher for sound quality, and saving $51 with the Hisenior Mega5EST 7th Anniversary Edition does not make up for the sound-quality gap.

Pros: A single 9.8mm dynamic driver earns a preference score of 75 from crinacle, and squig.link measurements show a 3.2 dB upper bass lift that gives a warm, punchy foundation without bloating the mids. The upper mids sit right on target, so vocals come through clearly, and the tuning suits warm and V-shaped tastes. At 30 ohms and 113 dB sensitivity it runs well from a phone, and it rates higher than the DUNU Zen and Unique Melody MEXT.
Cons: Across hobbyist measurements a 7 dB peak near 11.2 kHz adds sparkle that can tip into sibilance or splash on bright recordings. The presence band sits 2.2 dB low with a dip near 6.1 kHz, softening some edge on vocals and snare.
