Short answer: a tie on sound quality. Both are rated 4.1/5 (#364 and #350 of 1291 in-ear headphones) at nearly the same price ($105 vs $109), so choose on features and fit.
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.
The case for the Tin HiFi P1 Max II: A planar IEM that measures well across fourteen measurements (score 75), with bass on target down to 20 Hz. Watch for: At 98 dB sensitivity it needs more power than most IEMs, so a dongle DAC helps, and treble sits about 3.1 dB below target.
Buy the BEEP Audio Azure or the Tin HiFi P1 Max II on features: they are rated the same for sound quality at close to the same price.

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.
