Here's what I think happened.
Bunch of people gathered in a room and one of them told the others - "What if we take a high quality dynamic drivers similar to those in Moondrop Kanas Pro and Tanchjim Oxygen , put them in high quality metal body and sell the earphones for 30$?"
Silence in the room, deep breath, after that the boss said - " sure, why not, let's see what will happen"
That is how the Blon BL03 came out.
I bought two pairs after a saw some measurements and reviews, i was sure that i am gonna like them. Was right, after i heard the first pair made a purchase for one more, it was hard to believe at first, was expecting good sound for the price of 30$, not a similar sound quality compared to Moondrop Kanas Pro.
To get the best performance from them you need aftermarket eartips (longer than the stock, nothing fancy) and i use soft aftermarket balanced cable.
Build, fit and comfort
The build is great, fit and comfort great with aftermarket tips
Isolation
The isolation is average at best, the fit is not very deep and they are vented
Overall sound signature.
Blon BL03 is L shaped, sub bass focus with neutral mids and treble.
Bass
High quality bass, not only for the price but in general.
The shape, as it should be - rise in the sub bass, mid and upper bass with small boost lower in level compared to the sub bass. I find that type of tuning the most natural, you get impact without bleeding into the mids, no boominess. The bass impact is visceral but not very big, it is over the neutral DF target but is not a bass head in ear. Detail retrieval is very high for the price, excellent bass texture, it moves between the notes in a effortless way. Control of the bass is also very good, never bloated, without loosing control no matter the volume level, it is always tight and clean bass, amazing with high quality recordings with real instruments.
I am trying all my in ears with sub bass boost every time, to see if they can be fun sounding for electronic music and doom metal (i like a lot of bass for those types of music), BL03 does not disappoint, with about 5db boost under 60hz the bass is significantly more, retaining the texture and control, carbon drivers respond very well to bass EQ.
Overall great bass response, very well controlled, deep and textured.
Mids
Midrange sound very even and open, tonally correct. No recession, no big narrow spikes or wide overemphasis anywhere. It is not completely free of coloration, it has a bit of warmth from the mid and upper bass, but is not a lot, also in the upper mids it sound very open and lively, no depression there to my ears.
Male vocals sound realistic and clean, female vocals sound a touch more open and dynamic compared to male vocals. Instruments in that area are clean with good amount of body, never thin or overly thick, just the right tonality with full and clear at the same time performance. Overall impressive midrange performing great with every type of music.
Treble
The treble have a neutral tone. The extension is slightly better than average, they go up to about 12-13khz. The best thing for me is that the treble is not overly forward and sibilant. It is a very rare thing those days to have neutral sounding treble coming from China. The timber is realistic and clean, they have some sparkle but it is just there without drawing too much attention. Good amount of air and micro details. Detail retrieval is very high for the price avoiding harshness and sibilance even with high volume. Overall not the most extended treble but with natural clean tone.
Soundstage and imaging.
Soundstage size is above average, there is no dominating side, it sound like it is similar size in all directions.
Imaging is very good, it has good positioning, even on fast complex tracks is keeping the instruments well separated with easy to hear positions. The background is dark but not the blackest, some of my BA earphones have blacker background and the imaging is better, but for single DD with that price the imaging is very good.
Comparisons
Bl03 vs CNT1
At first when i started to listen i was not very happy with the CNT1, i changed the black filter with the gold one and decided to give them time, after a couple of hours they sounded better to me, probably i was adjusting to the sound. Keep in mind that the CNT1 is at around 25 hours of playing.
Bass
BL03 has more sub bass, CNT1 more mid bass.
Blon have better texture and details, CNT1 is very punchy and tight but the texture is not as good.
CNT1 has sort of a rough, tight impactful punch, BL03 is more clean and effortless.
Mids
Blon have more open sounding mids, it is dynamic and very clean.
CNT1 has more laid back mids and they are not as open sounding
Treble
Blon have more realistic timber to the treble, CNT1 have sparkle but with a bit of a grain to it.
BL03 vs Kanas
Bass
Kanas have a little bit more bass overall, the tonality is very similar, sub bass focus with some mid bass emphasis but lower in level compared to the sub bass.
Blon have better speed and texture, Kanas is more dramatic sounding with longer decay.
The other thing is that Kanas with bass EQ can rattle your skull , it is very wide and huge bass when you EQ them, the Blon can have big impact with a boost but not at the same level as Kanas.
Mids
Blon have more open sounding mids, Kanas have warmer, lusher tone to them.
I like both types of tonality, Blon cleaner and more open with more upper mids, Kanas calmer and more euphoric.
Treble
Kanas have a sparkle in the upper treble, it sounds like it is high, over 12-13khz, that gives them more air and the treble to me sound very sweet and gentle. Before that peak it has depression somewhere, that makes the treble not very transparent but very enjoyable to me nevertheless.
Blon sound more tonally correct in the treble, the dipped area in Kanas is present on Blon, that makes the tone of the treble more realistic.
Conclusion
One of my all time favorites, i like them better than the CNT1, equal with Kanas.
For the price they are unbelievable.
Everything below 5 out of 5 rating is a crime against humanity.
Have a good one.
