Short answer: the Canpur CP74E. It ranks #673 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $2,899; the Noble Audio Sultan ranks #695, rated 3.6/5, and costs $2,900, so there is not much of a tradeoff to weigh.
The case for the Canpur CP74E: A broadly balanced tuning with a preference score of 70 against the Harman target. Watch for: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Noble Audio Sultan does well: Bass extends on target to 20 Hz with about 2.6 dB of extra midbass in HypetheSonics’ measurement, giving a warm, full low end, and its 2.4 dB average deviation is fairly smooth. The tradeoff: A 7.4 dB dip near 3.2 kHz and a 3.4 dB shortfall across 3 to 6 kHz recess vocals and the attack of guitars and pianos.
Buy the Canpur CP74E. It is rated higher for sound quality than the Noble Audio Sultan and costs less, so only choose the other one for a particular feature it 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.
