Verdict

The Klipsch Image S4i II is a high-performance in-ear headphone featuring 8.5mm dual-magnet micro-speaker drivers and a frequency response of 10Hz to 19,000Hz. It is distinguished by its patented oval ear tips that provide superior comfort and up to -16dB of passive noise isolation, alongside a durable, tangle-resistant flat cable and an Apple-friendly three-button inline remote with a 360-degree microphone. Main pros include its lightweight 11.9g design, low 18-ohm impedance for easy driving, and clear, nuanced sound quality for the price. However, notable cons include limited compatibility of the remote with Android devices, a lack of sweat resistance for heavy workouts, and bass response that some users may find insufficient in depth and power.

(Reviews last updated: June 2026)

What customers like about Klipsch Image S4i II?

  • Patented oval silicone ear tips provide a very comfortable and secure fit for most ear shapes.
  • Balanced and clear sound quality for the price, with notable detail in mids and highs.
  • Upgraded flat cable is significantly more durable and tangle-resistant than the original model's cord.
  • Excellent passive noise isolation due to the tight acoustic seal created by the ear tips.
  • Includes a functional three-button inline remote and microphone optimized for iOS devices.
  • Comes with a protective and lightweight compact carrying case (often a metal tin).

What customers dislike about Klipsch Image S4i II?

  • Bass response may be too subtle for 'bass-heads' or those seeking heavily emphasized low-end thump.
  • The straight-jack design can be a point of failure compared to L-shaped plugs.
  • Inline remote buttons are smaller and more flush than previous versions, making them harder to use by feel.
  • Lacks sweat-resistance, making them less suitable for intense gym sessions compared to the 'Rugged' version.
  • Full remote functionality is limited to Apple devices; Android users may experience inconsistent controls.
