Short answer: the KZ DQ6S, though neither ranks well in its class. Both are rated 2.9/5 for sound quality (#1017 and #1023 of 1291 in-ear headphones), and the KZ DQ6S costs $28.99 against $34 for the KBEAR Pecker, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the Intuaura Reference 2019 instead, ranked #7 at $34.99.
The case for the KBEAR Pecker: Bass is lifted about 3.7 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: Presence sits about 3.1 dB low with a 7.7 dB dip near 11.9 kHz, so vocals and instruments lose some bite.
The case for the KZ DQ6S: It is very inexpensive and its 116 dB sensitivity with 25 ohm impedance means any phone drives it loudly. Watch for: Those measurements show a 7.4 dB peak near 8.2 kHz that can make sibilant vocals and cymbals sound sharp, alongside a 6.8 dB dip near 3.2 kHz that pushes voices back.
Buy the KZ DQ6S. Both are rated the same for sound quality, and it costs $5.01 less than the KBEAR Pecker.

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.
