TRUTHEAR Zero:BLUE2SoundGuys Headphone Preference Curve
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

The verdict
Great for gaming, but only for those looking at a bass-rumbling casual action gaming experience. For music listeners, the bass may be too much even for some bass heads. For those who want the bass to take center stage, this IEM is for you.
✓What we like
✓Bass heavy
✓Spatial width and depth
✓Flashy design
✓Separate cable with inline mic
✕What could be better
✕Fatiguing bass to some
✕Annoying to wear for long hours
