Third-party reviews

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

What customers like about Koss I150

  • Includes a travel case/bag for safe transportation
  • Features an in-line control panel for easy volume and playback access
  • Provides decent passive noise reduction via an acoustic seal
  • Extremely low impedance (8 Ohms), making them very easy to drive even with low-power mobile devices
  • Excellent value for money when purchased at discounted prices
  • Good sound separation between bass, treble, and vocals

What customers don't like about Koss I150

  • Requires high volume settings on devices to achieve reasonable listening levels
  • Does not sit deep within the ear canal, which can impact fit and total noise isolation
  • Sound can feel 'lacklustre' compared to other mid-range competitors
  • Lacks premium features found in newer models, such as active noise cancellation (ANC) or a detachable cable
  • Design does not allow them to be folded for more compact storage

Verdict

The Koss i150 is a pair of isolation in-ear headphones featuring a broad frequency response of 10 Hz to 20,000 Hz and an ultra-low impedance of 8 ohms, making them highly efficient for use with smartphones and portable devices via a standard 3.5mm jack. These headphones are characterized by their dynamic elements that deliver robust sound, a sound pressure level of 102 dB, and an integrated in-line microphone with a push-to-talk button for seamless communication. Key pros include a customizable fit with three sizes of silicone ear cushions, passive noise reduction for improved isolation, and the inclusion of a protective carrying case and a 4-foot straight cord. Some users may find the non-detachable cable and lack of advanced features like active noise cancellation or a foldable design to be significant cons.
