(True Wireless Earbuds Review) EarFun Free Mini: The V-shaped signature emphasizes low frequency and balance typical of the Free series. Sound balance is good enough to be considered low-priced, but lacking in resolution.

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 interrupted when there is an obstruction in between, but the music is still audible to a reasonable degree, although there are some skips and interruptions after that.


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

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

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


The EarFun Free Mini offers the excellent sound balance typical of EarFun at a low price, with the dynamism and groove typical of the Free series, and a deep low frequency range that is quite enjoyable.


However, when compared to the QCY T17, the Free Mini has better sound balance, but the T17 is by far superior in terms of resolution, making it hard to believe that it is in the same price range as the T17.

General comment

Even with the EarFun Free Mini, EarFun demonstrates its exceptional sound balancing technology and succeeds in providing good quality sound in the entry-level class. However, it is true that this is not a model that excels in resolution, and in this respect it falls far short of the price-over-range high-resolution sound of its rival, the QCY T17. Therefore, it is not highly recommended.
