What the Hidizs MK12 Turris does well: A broadly balanced tuning with a preference score of 66 against the Harman target. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.

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.
