What reviewers said
KZ ZAX
The KZ ZAX is a budget-friendly hybrid IEM packing a 10mm dynamic driver alongside seven balanced armatures, delivering impressive technicalities like imaging and soundstage for the price. It's easy to drive and offers a comfortable fit, though its bass can be heavy and sluggish, which may muddy balance and recess lower mids. Overall, it's a solid, incremental upgrade for those seeking a familiar KZ tuning with strong value.
