Short answer: the Moritz Dragon. It ranks #208 of 450 in-ear headphones by sound quality, rated 4.2/5, at $555.99; the Oriolus Isabellae ranks #217, rated 4.1/5, and costs $600, so there is not much of a tradeoff to weigh.
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. The tradeoff: 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 Moritz Dragon. It is rated higher for sound quality than the Oriolus Isabellae and costs less, so only choose the other one for a particular feature it does better.

Oriolus Isabellae: $600.00 Shenzhenaudio eBay
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.
