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.

✓Fantastic value
✓Replaceable two-pin cable
