Short answer: the Punch Audio Portazo. Both are rated 3.0/5 for sound quality (#999 and #1002 of 1291 in-ear headphones), and the Punch Audio Portazo costs $170.10 against $179 for the BQEYZ Frost, with sound quality a draw, the lower price decides it.
What the BQEYZ Frost does well: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. Watch for: 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 Punch Audio Portazo: Bass is lifted about 3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: Presence sits about 3.7 dB low with a 5.8 dB dip near 5.8 kHz, so vocals and instruments lose some bite.
Buy the Punch Audio Portazo. Both are rated the same for sound quality, and it costs $8.90 less than the BQEYZ Frost.

Frequency Response Compared
