I’ve been using the KZ ZS12 PRO X IEMs for 5 days, paired with mi Sony NW-WM1AM2 DAP. My impressions are based on this trial period.
Build & materials: They feel solid and well-made, with a metal shell.
Comfort & fit: Very comfortable, even after long listening sessions.
Sound: The bass is present and well-balanced, the mids are forward (especially female vocals), and the treble has nice detail without being fatiguing.
Soundstage: Good sense of space, not overly wide but natural.
Accessories: Comes with a 3.5 mm cable. The cable material feels basic, but it does the job fine at this price point.
Value for money: Excellent. The sound quality feels like it belongs to a more expensive product.
Conclusion:
Overall, these IEMs deliver a very satisfying experience, especially for anyone looking for detailed sound at an affordable price.
