Short answer: the Sony MDR-EX10, though neither ranks well in its class. It ranks #1151 of 1291 in-ear headphones by sound quality, rated 2.1/5, at $24.99; the KBEAR Rosefinch ranks #1232, rated 1.2/5, at $22.99. With prices this close, go by the sound-quality ranking rather than the cost. Both are rated below 3.0/5 among the 1291 in-ear headphones, and the EPZ G10, ranked #16 at $23.74, is a better place to start if sound quality matters.
The Sony MDR-EX10 is the better-sounding option. Bass is lifted about 5.3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: A 4.3 dB peak near 9.6 kHz can make cymbals and sibilance sound sharp.
The case for the KBEAR Rosefinch: Bass is lifted about 6.1 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 4 dB low with a 6.1 dB dip near 5.8 kHz, so vocals and instruments lose some bite.
Buy the Sony MDR-EX10. It is rated higher for sound quality, and the $2 saving on the KBEAR Rosefinch is not enough to make up the difference.
