Short answer: the Tanchjim Kara. Both are rated 4.2/5 for sound quality (#288 and #251 of 1291 in-ear headphones), and the Tanchjim Kara costs $179 against $189.99 for the EPZ P50, and with sound quality even, the cheaper one is the better buy.
Why pick the EPZ P50: The median of 28 hobbyist measurements gives it a very good Harman preference score of 77 with a 1.56 dB spread, and its mids sit within about 1.3 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 3.1 dB low with a 6.2 dB dip near 6.7 kHz, so vocals and instruments lose some bite.
Why pick the Tanchjim Kara: The median of 23 hobbyist measurements tracks the Harman target closely, with a 1.93 dB spread and lows, mids and upper mids all within about 2 dB, so vocals and instruments sound natural and even. The catch: The 3 to 6 kHz presence region sits about 3 dB low, which softens vocal bite and attack a little.
Buy the Tanchjim Kara. Both are rated the same for sound quality, and it costs $10.99 less than the EPZ P50.

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.
