Short answer: the DUNU Kima Classic. It ranks #39 of 450 in-ear headphones by sound quality, rated 4.6/5, at $22.99; the Tanchjim Ola Bass ranks #67, rated 4.5/5, at $22.99. Close enough in price that the sound-quality gap is the deciding factor.
The case for the DUNU Kima Classic: Across 10 hobbyist measurements on squig.link it earns a preference score of 81.6 with only 1.22 dB of deviation, so the tuning stays close to what most listeners prefer from deep bass through the upper mids. The catch: A 6.6 dB dip near 10.9 kHz takes some sparkle and shimmer off cymbals.
Why pick the Tanchjim Ola Bass: In the median of five squig.link measurements it scores 80.2 for preference, and its treble is remarkably even, with no peak larger than 1.6 dB or dip deeper than 1.9 dB between 1.5 and 12 kHz. Watch for: Sub-bass trails the midbass by about 3 dB, so the deepest rumble is lighter than the bass emphasis above it.
Buy the DUNU Kima Classic. It is rated higher for sound quality than the Tanchjim Ola Bass at the same price, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
DUNU Kima Classic: $22.99 Amazon eBay
Pros: Across 10 hobbyist measurements on squig.link it earns a preference score of 81.6 with only 1.22 dB of deviation, so the tuning stays close to what most listeners prefer from deep bass through the upper mids. Bass sits about 1.2 dB above target and sub-bass reaches 20 Hz without rolling off, giving kick drums real weight without muddying vocals. The single 10mm dynamic driver at 32 ohms and 108 dB plays loudly from a phone dongle, and it carries a higher rating than the pricier KBEAR KB01.
Cons: A 6.6 dB dip near 10.9 kHz takes some sparkle and shimmer off cymbals. There is no inline microphone, so it cannot double as a calling headset.

Tanchjim Ola Bass: $22.99 Amazon eBay
Pros: In the median of five squig.link measurements it scores 80.2 for preference, and its treble is remarkably even, with no peak larger than 1.6 dB or dip deeper than 1.9 dB between 1.5 and 12 kHz. A 2.1 dB bass lift gives the warm, punchy low end its name promises. At 126 dB/Vrms and 16 ohms it runs effortlessly from a phone, and the inline mic handles calls.
Cons: Sub-bass trails the midbass by about 3 dB, so the deepest rumble is lighter than the bass emphasis above it. Low mids sit about 1.1 dB above target, which can make dense mixes sound slightly thick.
