What customers like about Onkyo IE FC300

  • Powerful, punchy sub-bass that mimics a subwoofer experience without being muddy
  • Wide soundstage and impressive imaging for a closed in-ear monitor
  • Stylish and solid build quality with an attractive aluminum driver housing
  • Detachable, tangle-free flat elastomer cable that is easy to replace if needed
  • Easy to drive from standard mobile devices, though they scale well with amping
  • Comfortable fit for most users due to an angled design and soft ear pads

What customers don't like about Onkyo IE FC300

  • Notorious reliability issues with the MMCX cable connectors, often resulting in intermittent sound or complete failure after a few weeks
  • Recessed or laid-back treble that may lack the clarity and sparkle desired by 'treble-heads'
  • Shallow seal that can lead to poor isolation from external noise and a tendency to pop out during active use
  • Large housing size can cause physical aching in the ears during long listening sessions for some users
  • Lack of an integrated remote or microphone on the standard cable for phone calls

Verdict

The Onkyo IE-FC300 is a high-performance in-ear headphone featuring large 14.3 mm dynamic drivers housed in vibration-damping aluminium and ABS resin sub-chambers for enhanced bass response. It delivers a wide frequency range of 15 Hz to 22 kHz with a 32-ohm impedance and a sensitivity of 105 dB/mW, making it easy to drive with portable devices. Main pros include a detachable, tangle-free elastomer cable with gold-plated MMCX connectors, a relatively wide soundstage for in-ears, and a weight of only 12 grams for comfortable use. However, some users have reported that the proprietary MMCX connectors can become intermittent over time, and the cable lacks an integrated remote and microphone for mobile calls.
