What reviewers said
KZ Zenith
The KZ Zenith is a wired, single-dynamic-driver IEM that delivers a balanced, non-fatiguing sound with punchy bass, detailed mids, and smooth treble. It's highly sensitive and easy to drive, making it a versatile choice for portable use, while its build quality and fit are praised. Despite a few minor caveats, it offers strong technical performance and competes well above its modest price point.

Sennheiser CX 80
The Sennheiser CX 80 is a budget-friendly wired USB-C earphone that focuses on delivering clean, balanced sound with a straightforward design. Its compact 9.7mm dynamic drivers provide decent bass and clear mids, making it a solid choice for everyday listening without extra features like Bluetooth or ANC. While the build feels light and comfortable, the lack of volume controls and average microphone quality keep it from being a standout option.

- Pro:Clean, balanced sound with decent bass
- Pro:Lightweight and comfortable fit
- Con:No volume buttons on the cable
- Con:Microphone quality is only average
- Con:Lacks wireless and noise-canceling features
