Short answer: the NiceHCK DB2, though neither ranks well in its class. It ranks #1061 of 1291 in-ear headphones by sound quality, rated 2.7/5, at $22.99; the Sony MDR-EX10 ranks #1151, rated 2.1/5, and costs $24.99, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the EPZ G10 instead, ranked #16 at $23.74.
The NiceHCK DB2 is the better-sounding option. 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.
The case for the Sony MDR-EX10: Bass is lifted about 5.3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The catch: A 4.3 dB peak near 9.6 kHz can make cymbals and sibilance sound sharp.
Buy the NiceHCK DB2. It is rated higher for sound quality than the Sony MDR-EX10 and costs less, so only choose the other one for a particular feature it does better.
