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. Music is not interrupted even when interrupted by obstructions.

 

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

Sound quality

REW Frequency Response

Earfun Free 2S

 

Sound quality description

Earfun Free 2S has a typical studio tuning signature that is almost completely neutral.

 

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

 

Please see here for detailed reviews on sound quality.

  

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

 

The Earfun Free 2S is an excellent neutral-balanced sounding earphone. The emphasis on low frequencies continues the tradition of the previous Free series, but the highs sound smoother and slightly more docile, more like the Air series.

 

The balance is suitable for everyone, but if you liked the shimmering, subtle highs of the previous Free Series, you may find them a little too less to your liking. If anything, the sound is more suited to those who liked the sound of the conventional Air series but thought it lacked low frequencies.

Sound quality features

Pros
  • Good sound balance
  • Not bad original sound fidelity
  • Good texture
  • Excellent localization
  • Good high-frequency extension
  • Good listening comfort
  • Good focus on midrange
  • Deep and heavy but not fat, tight and smart low frequency range

 

Cons
  • Low resolution
  • High frequencies that are somewhat too transparent in presence and do not emerge from the background

 

General comment

The Earfun Free 2S is a well-balanced earphone with a sound based on Earfun's typical studio tuning. Like the other models in the Free series, it has a tight and deep low frequency range, but the midrange and above are more like the Air series, so if you are expecting the lively V-shaped sound of the previous Free series, you may feel a little uncomfortable.
