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. Communication was momentarily interrupted when we put a barrier in between us, but it quickly returned and we were able to listen to music consistently.


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



The operating interface is a touch type.

Sound quality description

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


Picun X7 has a V- or U-shaped sound signature.


Please see here for detailed reviews on sound quality.


Lows / Bass

The Picun X7's low frequencies have ample presence and extend quite deep.


Bass drums are sufficiently weighted, sounding thick and powerful, with ample rumble.


The electric bass is also sufficiently black and has good spaciousness.


In general, it is likely to satisfy heavy bass enthusiasts quite well.



The midrange is heard in a darker position within the overall sound.


Although the texture is quite accurate, the overall sound is dry and lacks lushness because the edge is over-emphasized and the overall sound tends to sound a bit clunky.


Guitar edges sound nice, but the snare sounds a bit rattly, which I don't like. The overall impression is a metallic sound. Vocals tend to be a bit shouty and harsh due to the rather high level of sibilance.


High-frequency definition is relatively lacking, so detail is not great, but the sense of separation is not bad, but the overall expression is not very expressive. It lacks fineness.


Highs / Treble

High frequencies are a bit tame overall. Extension is also much lacking.


There is a distinct lack of energy in the upper highs, which leads to a lack of detail and air, and combined with an overemphasis on edges, makes the whole thing sound choppy and stuffy.


It is clear that the X7's weak point is in these highs, where a little better adjustment would have resulted in a more decent sound.


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


The Picun X7's sound has a poor range for a dual dynamic driver, and it seems as if a single dynamic driver would have been a more decent choice. If you like a glaring sound with a strong edge, we can recommend it, but it is not a very attractive option for many people.


Sound quality features

  • Sound field with a sense of depth
  • Accurate texture
  • Forward localized
  • Edgy sound
  • Gleaming Sound
  • Heavy


  • Significantly lacks high-frequency extension
  • Lack of detail
  • Shouty vocals
  • Sounds metallic
  • Low resolution


General comment

The Picun X7 is an attractive fully wireless earphone with dual dynamic drivers at a low price. However, its sound is unfortunately a bit quirky and not really suitable for everyone. On the other hand, if you look beyond sound quality, it has good communication quality, is quite well designed, and is easy to operate with almost complete music control using only the earphones.
