The table shows a most important technical characteristics of FiiO F5 FiiO RC-B

*Center channel headphone is received by averaging between left and right channels

*impedance value in the table for channel



Test conditions
  • Type of headphones: In-Ear or Tablet
  • Measurements were performed on the stand:
    • Solid simulator-bushing SIEC (emulation of auditory channel)
  • Headphone's impedance has not been tested
    • The model use internal headphone amplifier
    • Can be used only with special AMP
    • By other reason
