Short answer: the Sivga Lyrebird. Both are rated 3.0/5 for sound quality (#988 and #1002 of 1291 in-ear headphones), and the Sivga Lyrebird costs $149 against $179 for the BQEYZ Frost, with sound quality a draw, the lower price decides it.
Why pick the BQEYZ Frost: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The tradeoff: Presence sits about 5.5 dB low with an 8.1 dB dip near 3.5 kHz, so vocals and instruments lose some bite.
The case for the Sivga Lyrebird: Upper treble lifts about 3.1 dB for extra air and sparkle. The tradeoff: A 5.1 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
Buy the Sivga Lyrebird. Both are rated the same for sound quality, and it costs $30 less than the BQEYZ Frost.

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.
