ZTECH’S PERSONAL REVIEW
KZ Castor Harman Target / Enhanced Bass dual dynamic driver IEMs with 4-level tuning switches and high-purity oxygen-free copper cable. The physical switches actually work and let you dial in extra sub-bass impact or crisp treble clarity depending on whether you're listening to music or hunting footsteps in FPS games.
The included switch tuning pin is small; keep it safe in your desk drawer. The ear shells are slightly thicker than standard single-DD IEMs due to the dual driver stack.
