Short answer: the Moondrop Harmon. It ranks #38 of 450 in-ear headphones by sound quality, rated 4.7/5, at $349.99; the Inawaken Twilight-DS ranks #113, rated 4.4/5, at $349. The price gap is small enough that the sound-quality ranking should decide it.
What the Moondrop Harmon does well: Across 10 hobbyist measurements on squig.link it scores 82 for preference, with bass held within about half a decibel of target down to 20 Hz, so low end is clean and controlled. The tradeoff: A deep 6.9 dB dip near 10.3 kHz and treble about 2 dB under target from 6 to 10 kHz make cymbals and acoustic detail sound subdued.
Buy the Moondrop Harmon. It is rated higher for sound quality, and the $0.99 saving on the Inawaken Twilight-DS is not enough to make up the difference.

The Two Headphones In Full
Moondrop Harmon: $349.99 Amazon eBay
Pros: Across 10 hobbyist measurements on squig.link it scores 82 for preference, with bass held within about half a decibel of target down to 20 Hz, so low end is clean and controlled. Three 10 mm dynamic drivers at 114 dB/Vrms play loudly from a phone. The slightly warm, relaxed tuning suits listeners who are sensitive to treble glare.
Cons: A deep 6.9 dB dip near 10.3 kHz and treble about 2 dB under target from 6 to 10 kHz make cymbals and acoustic detail sound subdued. Its rating sits below the IOAudio Sogno and AKG N5005 at a similar price, and there is no built-in microphone.
