Why pick the BQEYZ Winter2: A 12mm dynamic driver paired with a piezo bone conduction driver, with modular plugs. Watch for: Treble sits about 2.9 dB below target, a dark, relaxed balance.
The case for the Elysian Acoustic Labs Annihilator: A broadly balanced tuning with a preference score of 68 against the Harman target. The catch: An uneven response, 2.1 dB standard deviation from target.

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.
