Reviews last updated: November 2026 · How we calculate this

What customers like about Onkyo IE CTI300

  • High-quality, balanced, and natural sound signature with good detail
  • Strong bass performance that is tight and punchy without being overwhelming
  • Detachable and replaceable cable system for longevity
  • Integrated in-line remote and microphone certified for iOS devices (MFi)
  • Lightweight and comfortable design suitable for commuting
  • Passive noise reduction through an effective acoustic seal
  • Tangle-free flat elastomer cable design
  • Included travel bag for safe transportation

What customers don't like about Onkyo IE CTI300

  • Proprietary MMCX connectors can be prone to intermittent connection issues over time
  • Higher price point compared to non-Apple certified versions due to MFi licensing costs
  • Lacks active noise cancellation (ANC), relying solely on passive isolation
  • Sound can feel slightly congested or less refined when compared to high-end, more expensive sealed headphones

Verdict

The Onkyo IE-CTI300 is a premium in-ear headphone featuring large 14.3 mm dynamic drivers housed in high-rigidity aluminum to deliver a balanced frequency response of 15 Hz–22 kHz. Key characteristics include an 105 dB/mW sensitivity, 32 Ohm impedance for easy driving by mobile devices, and a detachable 6N oxygen-free copper cable equipped with an iOS-certified inline remote and microphone. Main pros are its punchy bass supported by large sub-chambers, lightweight 12g design, and tangle-free flat cable construction. Available cons include the potentially fragile nature of the MMCX connectors and a cable length that some users may find slightly short for comfortable pocket use.
