For the price, it delivers strong value and comfortable fit, making it a solid pick for budget-conscious listeners.

KZ ZS4
The KZ ZS4 is a budget-friendly hybrid earphone combining a balanced armature with an 8mm dynamic driver for an energetic, bass-forward sound. It offers strong detail retrieval and a comfortable fit for the price, but its V-shaped tuning prioritizes excitement over neutrality. This makes it a fun choice for bass and treble enthusiasts, though purists may find its signature too assertive.
- Pro:Very affordable price-to-performance ratio
- Pro:Energetic, bass-forward sound with clear highs
- Pro:Comfortable and lightweight fit
- Con:V-shaped tuning can cause midrange bleed
- Con:Bass can be overly assertive for some tastes
- Con:Bright treble may come across as harsh
