KZ ZSN Pro XSoundGuys 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

The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it.

✓Liked: Good sound, Fantastic value, Replaceable two-pin cable

✕Could be better: Buds won't fit small ears, Controls don't reliably work
