Short answer: the ZiiGaat Doscinco. Both are rated 3.6/5 for sound quality (#706 and #756 of 1291 in-ear headphones), and the ZiiGaat Doscinco costs $269 against $279.99 for the ddHiFi Surface (E14D), with sound quality a draw, the lower price decides it.
What the ddHiFi Surface (E14D) does well: A broadly balanced tuning with a preference score of 69 against the Harman target. The catch: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the ZiiGaat Doscinco does well: The median of 14 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.04 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Watch for: Its 2.04 dB spread is less even than the best measured sets.
Buy the ZiiGaat Doscinco. Both are rated the same for sound quality, and it costs $10.99 less than the ddHiFi Surface (E14D).

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.
