Short answer: the Audio-Technica ATH-SPORT7TW. It ranks #993 of 1291 in-ear headphones by sound quality, rated 3.0/5, at $53.04; the KZ AS10 ranks #1016, rated 2.9/5, and costs $59.99, which makes this an easy call rather than a real tradeoff.
The case for the Audio-Technica ATH-SPORT7TW: Its tonal tilt of +0.01 sits close to the target, so the overall balance is neither dark nor bright. The tradeoff: A Harman score of 62 places it in the lower part of the in-ear rankings.
Why pick the KZ AS10: Five balanced armature drivers per side is an unusual layout at a modest price, and the bass sits about 6 dB above target between 60 and 200 Hz for listeners who want a thick, warm low end. Watch for: That bass boost spills into the low mids, 3.3 dB over target, which muddies voices and guitars, and a 6.4 dB peak near 11.9 kHz adds glare up top in hobbyist measurements on squig.link.
Buy the Audio-Technica ATH-SPORT7TW. It is rated higher for sound quality than the KZ AS10 and costs less, so only choose the other one for a particular feature it does better.
