Short answer: a tie on sound quality. Both are rated 4.0/5 (#395 and #381 of 1291 in-ear headphones) at nearly the same price ($93.93 vs $94.99), so choose on features and fit.
What the CVJ Nozomi does well: The median of 4 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.00 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The catch: A 6.6 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
What the Juzear Defiant does well: One dynamic driver and three balanced armatures keep bass almost exactly on target, within 0.5 dB from 20 to 200 Hz in squig.link hobbyist measurements, so low end sounds clean and full without bloat. Watch for: Presence around 3 to 6 kHz falls about 4.4 dB below target with a 6.4 dB dip near 6 kHz, which pushes vocals and guitar attack back and makes the sound feel veiled in the center.
Buy the CVJ Nozomi or the Juzear Defiant 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.
