Short answer: the EPZ Q5. Both are rated 4.9/5 for sound quality (#6 and #10 of 450 in-ear headphones), and the EPZ Q5 costs $99 against $129 for the TANGZU x AZLA Noir Blanc, and with sound quality even, the cheaper one is the better buy.
What the EPZ Q5 does well: The median of 28 hobbyist measurements gives it a preference score of 87 with only about 0.85 dB average deviation, so tonal balance is very close to what most listeners prefer. The tradeoff: The 10 to 16 kHz air region sits about 4 dB above target, so bright recordings and hi hats can sound slightly sharp.
Buy the EPZ Q5. Both are rated the same for sound quality, and it costs $30 less than the TANGZU x AZLA Noir Blanc.

EPZ Q5: $99.00 Amazon eBay
Pros: The median of 28 hobbyist measurements gives it a preference score of 87 with only about 0.85 dB average deviation, so tonal balance is very close to what most listeners prefer. Bass, midrange and lower treble all sit within about 1.3 dB of target, with a slight bass lift that adds warmth. It shares its rating with the EPZ P40 while costing noticeably less.
Cons: The 10 to 16 kHz air region sits about 4 dB above target, so bright recordings and hi hats can sound slightly sharp. A single dynamic driver and no built-in microphone mean no inline calling, and the Truthear Zero Blue 2 shares its rating for less money.
