Short answer: the IvipQ IE-01. It ranks #1048 of 1369 in-ear headphones by sound quality, rated 3.1/5, at $35; the KBEAR Pecker ranks #1101, rated 2.9/5, at $34. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the IvipQ IE-01: About 4 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. The tradeoff: An uneven response, 2.4 dB standard deviation from target.
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. Watch for: Presence sits about 3.1 dB low with a 7.7 dB dip near 11.9 kHz, so vocals and instruments lose some bite.
Buy the IvipQ IE-01. It is rated higher for sound quality, and the $1 you would save on the KBEAR Pecker does not close the gap.

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.
