Short answer: a tie on sound quality, though neither ranks well in its class. Both are rated 2.7/5 (#1062 and #1061 of 1291 in-ear headphones) at nearly the same price ($20.99 vs $22.99), so choose on features and fit. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the EPZ G10 ranks #16 at $23.74.
What the ND Planet does well: Bass is lifted about 3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: Presence sits about 3.9 dB low with a 13 dB dip near 11.9 kHz, so vocals and instruments lose some bite.
What the NiceHCK DB2 does well: Bass is lifted about 2.9 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The catch: Presence sits about 4.5 dB low with a 10.3 dB dip near 4.6 kHz, so vocals and instruments lose some bite.
Buy the ND Planet or the NiceHCK DB2 on features: they are rated the same for sound quality at close to the same price.

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.
