Build quality

The build quality of the QCY G1 meets the price standard. The design is stylish.






It fits well in the ear and is comfortable to wear.




Connection quality

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


I don't know because I haven't been in crowds, but it is stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The sound is uninterrupted and I can listen to music consistently, even across obstructions.


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

Sound quality description

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


The sound signature of the QCY T17S has a balanced sound that is fairly close to neutral, and the sound balance is an improvement over the original QCY T17. In this sense, it is an improved version of the T17. However, the resolution has degraded considerably in the high frequencies, and the QCY T17 will probably sound clearer and higher quality to many people.


Please see here for detailed reviews on sound quality.


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


The QCY T17S has almost perfect audiophile-grade quality, with excellent sound balance that puts it in the company of the SoundPEATS Gamer No. 1 and EarFun Air Pro 2 at lower prices. The resolution is adequate and the audio specs transcend the price, but due to the lack of high-frequency resolution, a surprising number of people may find the T17s to be better when compared to the T17s.


Sound quality features
  • Excellent sound balance
  • Near-perfect textural representation
  • High fidelity of original sound
  • Highly transparent midrange
  • Delicate
  • Fresh
  • Metallic
  • High range with few unpleasant elements


  • Lacks a sense of edge
  • Lacks a sense of structure
  • Contours are easily blurred
  • Lower clarity in the high frequency range than T17, and overall resolution is reduced.
  • Lacks low-frequency volume and depth


General comment

We can't laugh at audio dreamers who are looking for true wireless earbuds that combine high sound quality with highly customizable apps at a low price point, just like the higher-end models. Because it is right in front of you: the QCY T17S is a revolutionary model of fully wireless earbuds with a highly customizable dedicated app and excellent sound balance.


When I saw the news that the QCY T17S won the "World TechMedia Recommendation" at CES2022, I wondered why EarFun did not. I didn't think they would be critically acclaimed, and I thought that EarFun must have made a superior product in that regard. But after getting the T17S, all mysteries were put to ice. Indeed, it would be impossible for the prestigious Audio Media Awards not to rate this earphone near the top, and the QCY T17S certainly beats the EarFun Free Mini in the same price range in almost every way.
