Short answer: the Final Audio E5000, though neither ranks well in its class. It ranks #1079 of 1291 in-ear headphones by sound quality, rated 2.6/5, at $274; the Technics EAH-AZ100 ranks #1115, rated 2.4/5, and costs $297.99, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
Why pick the Final Audio E5000: Bass is lifted about 4.1 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: Presence sits about 4 dB low with a 6.2 dB dip near 5.5 kHz, so vocals and instruments lose some bite.
What the Technics EAH-AZ100 does well: These true wireless earbuds offer active noise cancelling, Bluetooth 5.3 with LDAC and AAC, a claimed 10 hours of battery per charge and IPX4 splash resistance. The catch: In two hobbyist measurements on squig.link it scores only 53.6 for Harman preference with a 3.2 dB deviation.
Buy the Final Audio E5000. It is rated higher for sound quality than the Technics EAH-AZ100 and costs less, so only choose the other one for a particular feature it 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.
