Short answer: the Tanchjim Kara. It ranks #288 of 1291 in-ear headphones by sound quality, rated 4.2/5, at $179; the Agasound Sublimation Burnout ranks #371, rated 4.1/5, at $179. Close enough in price that the sound-quality gap is the deciding factor.
What the Tanchjim Kara does well: The median of 23 hobbyist measurements tracks the Harman target closely, with a 1.93 dB spread and lows, mids and upper mids all within about 2 dB, so vocals and instruments sound natural and even. The catch: The 3 to 6 kHz presence region sits about 3 dB low, which softens vocal bite and attack a little.
Why pick the Agasound Sublimation Burnout: A broadly balanced tuning with a preference score of 75 against the Harman target. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Tanchjim Kara. It is rated higher for sound quality than the Agasound Sublimation Burnout at the same price, which makes it the one to get unless you need something the other one does better.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
