What reviewers said
KZ ZST
The KZ ZST is a budget-friendly hybrid in-ear monitor that pairs a 10mm dynamic driver with a balanced armature for a lively, bass-forward sound. It offers solid low-end punch and good detail retrieval for the price, but its uneven treble and slightly recessed mids can make some vocals and instruments sound harsh or distant. With a detachable cable and lightweight build, it's a decent entry-level option for bass lovers, though comfort and build quality are only average.

- Pro:Detachable cable for easy replacement or upgrades
- Pro:Very affordable for a hybrid driver setup
- Con:Treble can come across as piercing or harsh at times
