Samsung EO-IC100
Score: 83/100Rankings
The Samsung EO-IC100B USB-C earphones deliver clear, balanced sound with a built-in DAC and premium build, but lack ANC and a protective case. Suitable for users who need high-quality wired audio on USB-C devices.
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.
