The HearWiki takeAI-condensed
The KZ ZSA is a budget-friendly hybrid IEM with a warm, energetic sound, highlighted by deep bass and crisp, detailed treble. Its sturdy metal build and detachable cable add value, though the forward treble and sometimes heavy bass may not suit all listeners. Fit can be inconsistent depending on ear shape.

5:08KZ zsa Review (Gray) under $30
The reviewer finds the KZ ZSA to be a decent but not outstanding pair of earphones. They note that while the highs are detailed and the bass is booming, the mids are recessed and the soundstage is lacking, making them inferior to other KZ models in the same price range. The build quality is praised for its premium aluminum shells and copper cable, but the fit is problematic, especially for those with larger ears, as the earphones tend to fall out.

5:33KZ ZSA Review
The reviewer finds the KZ ZSA to be a well-built, premium-feeling budget earphone with a bright, detailed sound, but notes that the fit is poor due to the small size and subpar stock ear tips, and that other KZ models offer better overall performance for a similar price.
