Intro

I don't think BLON was aware of what they did back then with the release of the BL-03. I also don't know how such a hype could have come about, because the BL-03 is undoubtedly a good budget IEM, but nothing more. Nevertheless, the BL-03 is always consulted when it comes to the best budget IEM, although there are still far more out there. But well, basically it is to be welcomed that an IEM can give pleasure to such a broad mass and that at such a price.

The BL-05 was then the eagerly awaited successor, but it left many fans of the BL-03 disappointed, because it is more technical, brighter and not as bassy as its predecessor. The BL-05s now wants to fill the gap and tries to unite both opposites. Let's see if that works.

Handling

BLON doggedly sticks to its accessories and presentation, which we already know from the BL-03 and the BL-05. Also to the "clear message" on the packaging. Well, the joke is also getting old, so here's to the essential:

The BL-05s is a twin of the BL-05 as far as the housing is concerned. However, it is only available in mint green, which is refreshing in color, but will also split tastes. The workmanship is very solid, but I think the sound openings are still a bit too short, but this is generally a problem of the BL-series.

Otherwise the cable is okay, but a bit fiddly and certainly not my first choice. I also don't find the enclosed silicone tips very helpful to achieve a good seal and secure fit, but here I can only speak for myself.

The isolation is quite good, as far as passively possible and of course a little bit tip-dependent. This also applies to the wearing comfort, which is quite pleasant for me.

Sound

I'm a bit surprised when I read reviews where it is said that the BL-05s should sound completely different from the BL-05 despite a very similar frequency curve. Okay, the BL-05s is supposed to use a new "3nd Generation 10mm CNT Diaphragm Driver" (BL-05 - 2nd Generation...), but how much is really perceived as a change and how much is just marketing. Impedance, sensitivity and frequency response did not differ at least.

The bass is pretty much on the same level as the BL-05, both qualitatively and quantitatively. The fact that it shows up a bit better and also gives more warmth to the signature is rather due to the reduction of the upper mids. I find the bass very well balanced, even if there is still a bit of pressure missing. Nevertheless it has a natural response, but can't give every genre the desired impact.

The mids remain largely untouched by the bass or better said the transition is smooth without distorting the mids. These are clear, clean and detailed, but they can't fully convince me either. Compared to the BL-05 they are easier to digest and not quite as bright, as they are a bit damped in the upper range, but not to such an extent that one could speak of a different tuning. They appear more supple and more mature, yet there are still nuances. The BL-05 has more crisp and assertiveness in the midrange, but also a tendency to shrillness. Sometimes voices still seem a bit thin to me, but still tonally authentic.
We are most sensitive in the upper midrange, especially when it comes to the perception of volume. So subjectively, I can make the BL-05s a bit louder to achieve the same volume level as the BL-05. However, this small difference already makes the bass a bit more present and a slightly warmer sound in contrast to the BL-05, as the weighting changes slightly. When comparing A/B, however, one quickly forgets on which side the BL-05 and the BL-05s are sitting, which of course has to do with the brain's adaptation, but also with the very familiar sound.

I like the trebles quite well. Here I see the "biggest" improvement compared to the BL-05 and BL-03. They sound natural and have an airy character. In total they are a bit more accentuated than on the BL-05, but play more relaxed and balanced, which is possibly due to the new driver. In addition, they convince with a high information density, which however never becomes obtrusive. The fact that the BL-05 sounds a bit brighter in comparison is rather due to the upper mids / lower highs.

In stage and separation I can't make out too big differences. The BL-05 subjectively separates a bit sharper, but the BL-05s seems more organic, also in imaging. But both have a good wide and acceptable depth.

Outro

Okay, from the general sound presentation there is no significant difference to the BL-05 in my opinion, at least concerning the basic tuning, but the devil is in the details. Through small but conscious adjustments a somewhat too bright and technical IEM became a still somewhat bright but more balanced and above all more audible IEM that sounds more mature. For those who own the BL-03 and want more balance, I recommend the BL-05s. If you own the BL-05 you probably already benefit from an equalizer, even if the new driver sounds a bit more organic/harmonic. If I have to classify the BL-05s within its price range, I prefer to go with the TIN HIFI T2 PLUS, which I find smoother, even though the BL-05s is an excellent IEM in its class.

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
