The table shows a most important technical characteristics of QCY T5

*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

Measurements of QCY T5 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The QCY T5 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
