Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about Koss Qzpro

  • High value for the price point
  • Lightweight design and relatively small for over-ear headphones
  • Effective at reducing low-frequency background noise like engine hums
  • Passive isolation is decent even without active noise cancellation
  • Integrated inline volume control for quick adjustments
  • Includes a fold-flat design for improved portability

What customers don't like about Koss Qzpro

  • Poor active noise cancellation performance compared to modern standards
  • Build quality feels cheap and flimsy due to all-plastic construction
  • Can be uncomfortable for some due to a high clamping force (tight on the head)
  • Known durability issues with hinges and thin cables breaking
  • ANC requires two AAA batteries and may produce a low buzzing or white noise
  • Sound profile is often described as muddy or bass-heavy with recessed highs

Verdict

The Koss QZPRO is a wired, over-ear headphone designed for travelers, featuring a combination of passive and active noise cancellation (ANC) powered by two AAA batteries for up to 30 hours. These headphones utilize dynamic elements to deliver a frequency response of 40–20,000 Hz, 32-ohm impedance, and a sensitivity of 90 dB SPL. Key advantages include a fully collapsible design for portability, soft leatherette closed ear cushions for an effective acoustic seal, and an included two-prong airline adapter. However, some users have noted that the ANC performance is primarily limited to low-frequency sounds, the build quality involves significant plastic use, and the fit may feel tight or uncomfortable during extended listening sessions.
