I decided to compare S8Pro with ProPhile 8 in order to give a reference to everyone reading.
Preamble :
The S8Pro and PP8 were second-hand purchase on Head-Fi and Tellement Nomade.
Fearless is one of the Chinese brands that is rising in the small in-ear world.
The model we are interested in today is their 8 BA called S8Pro. It is currently sold for 450€ on Aliexpress, 491€ on Amazon.de and 489$ at Linsoul. The felt quality is excellent, with a very ergonomic resin shell that allows an excellent fit. The box provided with is very practical and allows you to easily store a cable and 2 pairs of in-ear monitors. The stock cable makes a good impression but unfortunately it wasn't working when I received it.
InEar is a German brand well kown by audiophiles.
Until recently, the Prophile 8 was the brand's flagship. Composed of 8 BA, they are recognized for their balanced signature considered as a reference. They have on their shell 2 switches allowing a bass and/or treble boost. The ergonomics of the hulls is the best I have ever encountered in the sense that it allows a fit close to that of a pair of customs. They seem to be able to withstand anything, but the cable supplied with it is of poor quality. They are currently available at 1333€.

For the following review, I was able to test the PP8 and S8Pro with a WM1Z mod K, LPG and Cayin N8.
Sound :
If we already knew that InEar had succeeded in creating the ultimate monitoring pair with the PP8, Fearless offers us here its vision of a reference signature. And this is the commercial argument they use, since they recommend S8Pro on their website for professionals and producers. We are therefore faced with 2 interpretations of a balanced restitution.
Here are the Crinacle measurements (uncompensated) to compare PP8 (with bass boost) and S8Pro. Return below is done with the PP8 in this position.
Bass :
The peak of the Sub Bass (20 to 60Hz) and Bass (60 to 250Hz) is located at the junction of the two registers whose restitution is very linear and typical of BA. Fast and equally present on both pairs, the rendering is still a little different. They seem a little slower on the PP8 side due to a slightly longer "sustain". This gives a better impact for the S8Pro, a more physical feeling. However, some people may lack a real slam and a few subs that are found on Dynamic Drivers (DD) like the Trinity for example.
The quantity and unbooming nature of the basses offered here finally allow the rest of the registers to express themselves while providing a solid foundation for the music.
Mids :
The midrange is more matt and dense on the PP8 and more open and airy on the S8Pro, but with a very pleasant sensuality for both.
The Low-Mids (250 to 500Hz) is quite close and in the continuity of the basses on the 2 sets.
If we assume that the Mids (500 to 2000Hz) and High-Mids (2000 to 4000Hz) of the PP8 are neutral, we obtain a Mids a little behind on the S8Pro. Both men and women have slightly less warm voice tones. But at the same time, the High-Mids a little ahead allows to bring shine to these same voices and notes. The sound of the PP8 seems fuller but less luminous in comparison.
The 4000Hz peak of the S8Pro can also be a little annoying for some people depending on the recordings.
In comparison, Trinity Low-Mids are a litlle more recessed and Mids are even deeper and airier. The High-Mids is more flourishing, promoting development of harmonics and timbres efflorescence.
Highs :
The treble extension is quite similar on both in-ears. But due to the 4KHz peak of the S8Pro which extends a little beyond that, the high frequencies seem a little less present. They also seem a slightly less accurate on the S8Pro, more floating.
Relaxed and pleasant on the 2 pairs, they offer a beautiful resonance on the cymbals and allow them to have enough space to flourish. A nice success without brilliance.
In comparison, the highs of the Trinity are quite similar to those of the S8Pro in terms of quantity but sound more natural, much more accurate and much more aerated.
Soundstage:
With the PP8, we have a very wide but relatively shallow sounstage, height is rather average.
With the S8Pro, we move back a few rows in the audience but the singers are not closer to the musicians. The depth and width therefore improves slightly, as does the height.
However, we remain below the Zeus XIV in terms of width and the Trinity for depth and height.
The Magic Square:
As a result of the above, S8Pro seem to have a little more resolution and separation than PP8, except in the high frequencies where PP8 take over.
Definition and transparency seem to be of the same kind on both 8 BAs.
It should be noted, however, that S8Pro are more sensitive and dependent on recordings than PP8, which can sometimes increase recording whisper and bring out small imperfections.
In comparison, separation and resolution are better on Trinity, transparency and definition are a little higher too.
Final Thoughts :
As always, it's all about favorite taste.
If you want a soft, matte, dense and perfectly balanced sound, the PP8 are made for you. They will allow you to listen to your favorite songs for hours without fatigue by highlighting the production work. However, some might say that they are a little boring, flat and dull.
If you want a little spice and clarity without denaturing your songs and moving too far from a balanced playback, the S8Pro is for you. Gamblers and luminous, available for less than half the price of PP8, the Fearless are a very convincing proposal. But be careful if you have a 4KHz sensitivity and be aware that recording quality might be an issue.

Definition :
"Resolution is the ability to individualize a voice or instrument, so it is a synonym for detouring"
"Separation is the ability to feel space between musicians"
"Definition is the ability to perceive as much information as possible"
"Transparency is the ability to transcribe tones and subtleties of music"
