What reviewers said
KZ EDX
The KZ EDX is a budget-friendly wired IEM that delivers robust bass and impressive detail for its low price, making it easy to drive from a phone. While its soundstage and imaging punch above their weight class, the tuning leans aggressive with a hot upper-midrange that can cause listening fatigue. Overall, it's a solid value for bass lovers, though its harsh treble and basic accessories hold it back from being a universal recommendation.
