Connection quality

I tested it by connecting it to a Cayin N6II/E02 with AAC. The quality of the connection is excellent for the price range. I haven't been in crowded places, so I don't know, but it's stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The communication is not interrupted even when interrupted by a barrier, and the music plays fine afterwards, with no interruptions.


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

Sound quality description

With the Sonic Pro, SoundPEATS has announced that they are graduating from the V-shaped sound, and it seems that they have really aimed for a new, different sound. The low to mid frequencies are quite neutral, and the sound is more midrange oriented, similar to studio tracking monitors.


With the Gamer No.1 and now the Sonic Pro, SoundPEATS seems to have overcome its near-traditional obsession with low frequencies and begun to create sound on a new stage.


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

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


The SoundPEATS Sonic Pro is tuned for Japanese music and J-POP listeners who listen to Japanese vocal music, with accurate mid-range that is faithful to studio recordings, careful focus on mid-range and high frequency details, and obvious attention to the Japanese range.


I had no idea what was so Japanese sound about the Sonic, but the Sonic Pro sounded beautifully Japanese, and the lyrics were very easy to hear and the nuances of the music were easy to understand.


However, the sound field is narrow and the mid-high frequency range is a bit strong, so it tends to be a bit tiring to listen to.


Sound quality features
  • Proper focus on midrange
  • Natural texture
  • Constructive
  • Glossy and gorgeous mids and highs
  • Good vocal focus
  • Focus on Japanese register


  • Consonants that sound a little sharp and easy to hear
  • Lack of expandability
  • Narrow sound field
  • Strong sense of extrusion
  • Tiresome to listen to
  • Prone to shouting


General comment

SoundPEATS Sonic Pro has a sound that is focused on the Japanese register with an emphasis on vowels, making it suitable for Japanese people who enjoy Japanese music and J-POP. Its mid-range is almost neutral, allowing you to enjoy sweet and bright vocals in the center, and its mid-high range is highly impressive and gorgeous. It's a tuning that will stick with people who enjoy idol songs and the like, since vocals can be heard sparkling and clearly.

It also has excellent specifications and features such as low latency mode and wireless charging support.
