Yinyoo ZST
Score: 74/100
FiiO FF1
Score: 65/100Rankings
The YINYOO Easy KZ ZST is a budget-friendly hybrid IEM that combines a balanced armature and a dynamic driver for lively, detailed sound. Its ergonomic memory-wire design, multiple silicone tip sizes, and detachable cable provide comfort and versatility, while the lack of wireless features and occasional bass distortion keep it in the entry-level segment.
The FiiO FF1 is an entry-level wired earbud with a large 14.2 mm driver, high sensitivity, and a generous accessory bundle. While comfortable and easy to drive, its bass is modest and the semi-proprietary connector may limit upgrades.
