Short answer: the Moondrop Golden Ages. Both are rated 3.9/5 for sound quality (#478 and #499 of 1291 in-ear headphones), and the Moondrop Golden Ages costs $89.99 against $94.99 for the Juzear x Z Reviews Defiant, with sound quality a draw, the lower price decides it.
What the Juzear x Z Reviews Defiant does well: A broadly balanced tuning with a preference score of 73 against the Harman target. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Why pick the Moondrop Golden Ages: The median of 10 hobbyist measurements gives it a solid Harman preference score of 73 with a 1.84 dB spread, and its mids sit within about 1.3 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.2 dB low with a 7.9 dB dip near 10.9 kHz, so vocals and instruments lose some bite.
Buy the Moondrop Golden Ages. Both are rated the same for sound quality, and it costs $5 less than the Juzear x Z Reviews Defiant.
