Connection quality

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


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 momentarily cut off when there is an obstruction in between, and the communication is somewhat disrupted after that, but after a while the communication is restored and I can listen to music consistently.


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 aptX connection.


The Edifier X3 TO U is very well balanced with a slightly darker midrange, V-shaped, almost neutral sound signature. It is a comfortable listening model with little sharpness or sting.


Please see here for detailed reviews on sound quality.


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


X3 To U offers a fairly balanced, near-neutral sound. It is more midrange retraction and slightly more dynamism than neutral, but is more stable to listen to. Resolution and clarity, however, are on par with the price.
