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.

General comment

  • Original sound fidelity: A
  • Recommendation: A-
  • Personal preference: A-


The Edifier To-U6+ is not a bad choice for earphones under $100. The highs are well localized and have a consistent overtone presentation, making them ideal for listening to string music, etc. As is typical of Edifier, the highs are carefully produced, with a subtlety and consistency that makes them well-balanced and inoffensive.


It's not bad, but it's not particularly highly recommended. Considering the price, there are likely many better models.
