Short answer: the BQEYZ Cloud. Both are rated 4.5/5 for sound quality (#106 and #122 of 1291 in-ear headphones), and the BQEYZ Cloud costs $172.25 against $179 for the KBEAR Cepheus, and with sound quality even, the cheaper one is the better buy.
The case for the BQEYZ Cloud: The median of seven hobbyist measurements on squig.link gives the Cloud a preference score of 79.6 with only 1.46 dB of deviation, so it tracks the Harman target closely from deep bass through the upper mids. The tradeoff: Air above 10 kHz runs about 4.3 dB hot, with a 5.4 dB peak near 8.1 kHz, so cymbals and sibilant vocals can sound edgy on bright recordings.
What the KBEAR Cepheus does well: A two dynamic plus six armature hybrid that measures very well (score 79) with one of the tightest spreads from target in this group (1.43 dB). The tradeoff: Treble sits about 2.6 dB below target, slightly smooth and dark, and its score rests on only three measurements so far.
Buy the BQEYZ Cloud. Both are rated the same for sound quality, and it costs $6.75 less than the KBEAR Cepheus.

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.
