Short answer: the Moondrop Aria 2. Both are rated 4.1/5 for sound quality (#339 and #364 of 1291 in-ear headphones), and the Moondrop Aria 2 costs $99.99 against $105 for the BEEP Audio Azure, and with sound quality even, the cheaper one is the better buy.
Why pick the BEEP Audio Azure: A broadly balanced tuning with a preference score of 75 against the Harman target. The tradeoff: An uneven response, 1.9 dB standard deviation from target.
Why pick the Moondrop Aria 2: In squig.link measurements it reaches a preference score of 75 with a smooth response, deviating only about 2 dB on average from the Harman target. The catch: A 4.8 dB dip near 6 kHz and presence about 2.8 dB below target take some bite and detail off snares and consonants.
Buy the Moondrop Aria 2. Both are rated the same for sound quality, and it costs $5.01 less than the BEEP Audio Azure.

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.
