Short answer: the Fatfreq Hayabusa. Both are rated 4.2/5 for sound quality (#268 and #267 of 1291 in-ear headphones), and the Fatfreq Hayabusa costs $1,999 against $2,299 for the Shuoer Cadenza 12, with sound quality a draw, the lower price decides it.
The case for the Fatfreq Hayabusa: A preference score of 76 in crinacle’s measurement places its tuning reasonably close to the Harman target most listeners prefer. The tradeoff: The response is uneven, at 1.94 dB standard deviation from target, so some frequency regions stand out or fall back.
What the Shuoer Cadenza 12 does well: A preference score of 76 with deep, well extended bass, only 0.5 dB short of target at 30 Hz from its 10 mm dynamic woofer. The catch: An 8 dB dip near 5 kHz pulls the presence band 5.5 dB below target, so vocals, snare and guitar attack sound recessed and soft.
Buy the Fatfreq Hayabusa. Both are rated the same for sound quality, and it costs $300 less than the Shuoer Cadenza 12.
