(True Wireless Earbuds Review) QCY T13: Mellow sound that makes music sound majestic in a slightly relaxed soundstage. Highly customizable and long playback time. Excellent entry-level model, but only a little concerned about communication quality.

Package contents

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

  • QCY T13
  • Charging case
  • USB Type-C cable
  • Eartips (3 sizes)
  • Manual


Build quality

Build quality is at a good level considering the price. The design is as beautiful and transparent as white porcelain.




Fits well in the ear and is comfortable to wear. It is shaped to fit in the ear rather well.




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 a bit weak and tends to be a bit choppy at distances of about 5 meters. Also, the connection was broken when a barrier was placed.


There may be a small amount of background 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 QCY T13 delivers a spacious, deep sound that brings more low frequencies to the forefront while remaining neutral. Music will sound more grandiose, with an enhanced sense of scale. The clarity is high, and the bass-enhanced listening sound is quite well-balanced.


Please see here for detailed reviews on sound quality.


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


Although it is a low-priced model, the overall sound field is well adjusted so that the sound is relaxed and the instrumental sounds are slightly resonant and mellow, and the listening sound attacks the exquisite line between elegant and majestic, yet graceful. It lacks a sense of construction, so it is not for those who like a solid sound, but it is likely to satisfy quite a lot of people.


It is a sound that is appropriate for the QCY T13, which was created as an entry-level product suitable for everyone, and it matches the concept well.


Sound quality features
  • Large sound field with depth
  • Proper focus on the midrange
  • Elegance
  • Magnificent
  • Mild and mellow listening comfort
  • Rich in resonance


  • Lacks a sense of structure
  • Sound sounds a little sluggish


General comment

The QCY T13 has a well-balanced, low-frequency-leaning sound. It is carefully emphasized so that the soundstage sounds wide while maintaining balance very well, and it maintains detail well, giving an excellent listening sound that is pleasant to listen to. Although only the communication quality is a bit of a concern, the specs are excellent and the included app allows for customization of sound quality and usability, making these earbuds long-lasting after the initial purchase. They are very good as an entry-level model.
