(True Wireless Earbuds Review) QCY T17: Emphasis is placed on the sound field, and the sound is extended, fresh, high-resolution, and high-definition. However, the midrange is thin.

Package contents

There is no shortage of accessories. The package contains the following:

  • QCY T17
  • Charging case
  • USB Type-C cable
  • Eartips (3 sizes)
  • Manual


Build quality

The build quality is good, considering the price.






The fit is good. Probably not a problem for small ears.




Connection quality

I tested it by connecting it to a Cayin N6II/E02 with AAC.


I don't know, I haven't been in crowded places, but it is stable in my home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. Across a barrier, the connection is mostly fine, but does tend to break up slightly.


There may be a small amount of white noise, but most people probably won't notice it.

REW Frequency Response



Sound quality description

The QCY T17 is tuned to be neutral, but with more emphasis on the sound field. This is the same idea behind QCY's entry-level model, the T13, but the overall sound of the T17 is even higher frequency than the T13, resulting in a brighter, more extended, and crisper high-resolution sound.




The following review was tested on a FiiO M15 with an SBC connection.


Please see here for detailed reviews on sound quality.


Sound quality general comment
  • Original sound fidelity: A+
  • Recommendation: S-
  • Personal preference: A+


The QCY T17 is an overall higher frequency version of the T13, with more emphasis on the fidelity of the original sound and the sound field. You can enjoy a more extended sound, but the midrange is thinner and more airy, so the overall expression is less expressive. However, the resolution has been improved, probably due to the titanium drivers, and the overall sound quality is highly recommended over the T13.

  • Spontaneous sound
  • Delicate
  • Refreshing

  • Sounds flimsy
  • Weak attack


General comment

The QCY T17 has a refined sound that is a brighter overall version of the T13 sound. If you prefer a sound that is more delicate, brighter, fresher, and has a wider soundstage, the T17 is a better choice than the T13. I don't know if it is the effect of the titanium drivers, but the overall resolution is also much better than the T13.
