Short answer: the Kiwi Ears x B Media Chorus. It ranks #831 of 1291 in-ear headphones by sound quality, rated 3.5/5, at $39.99; the Whizzer HE01 ranks #862, rated 3.4/5, and costs $45, so there is not much of a tradeoff to weigh.
Why pick the Kiwi Ears x B Media Chorus: A single 10 mm dynamic driver with mid-bass about 3.7 dB above target gives a warm, punchy sound that suits warm and bassy listeners, and bass holds within 6 dB of target down to 20 Hz. The tradeoff: A Harman preference score of 67.4 in hobbyist measurements points to a colored tuning, with a 4.4 dB dip near 6.1 kHz that dulls instrument edge and a 5.2 dB peak near 8.1 kHz that can make cymbals splashy.
The case for the Whizzer HE01: For a budget single dynamic driver earphone it earns a preference score of 66.0 in crinacle’s measurement, with a warm tilt that suits listeners who prefer a relaxed, bass forward sound. The tradeoff: An 8.1 dB dip near 6.4 kHz and a treble band averaging 3.3 dB below target dull cymbals and blunt detail, while a 4.2 dB peak near 11.9 kHz adds an uneven, slightly metallic edge.
Buy the Kiwi Ears x B Media Chorus. It is rated higher for sound quality than the Whizzer HE01 and costs less, which makes it the one to get unless you need something the other one does better.

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.
