The z 4 fits better, but is a bit heavier, though not as much as the z 300. However, there is a difference in comfort. Not to forget that the z 4 was brilliant, the z 300 was better in listening comfort Z300 can be described as a relaxed, warm-dark tuned IEM with a slight V-shaped profile. It has good extensions on the subbass, but has a slight roll-off at the upper treble region. The mids are not perfectly neutral, but that's not the aim of the tuning direction after all. The Z300 is all about fun and musicality. The Z300 aren't BL03 upgrade, nor about pushing the bundaries of it's tuning DNA, nope, it ''cloud'' it instead, polish the balance to make it smoother and more ethereal. Tempotec V6 - The response of the Z300 sounds more clear and detailed when coupled with the V6. The mid range sounds forward and balanced, while the treble is more exuberant and full of good details. Because the bass is well-controlled and doesn't overpower the other tones, it sounds lively and crisp. I really like the pairing with the V6 because, aside from the imaging being sharper and the stage being larger, the technical performance feels the same.

This type of sound performance may not be for everyone though. Some people may find this a bit too warm for their tastes whilst some will adore this set very muchIf you look at the graph, you might think that the trebles have a similar tuning. But, in practice, the Z300's treble is softer, while the C3's has more energy, more crunch, more presence, but also more danger, because it is sharper and punchier. The Z300s are softer and I could say that, for many, they are sufficient. If you want more presence in the upper zone, the C3s have it. This particular frequency that this set has projects a rather smooth and relaxed quality from the upper mids to the presence part of the treble region. This will also give you a non-sibilant and zero-harshness that will give us a pleasant listening session but there's an underlying caveat on this one. Due to its leaning towards a more darker sound, it will not have that crisp, clarity and detail that detail lovers and analytical-type of listeners will prefer to.

Without a doubt, the best feature is the cable, along with the build quality and design of the capsules. A zipped pouch is missing, but the classic fabric pouch with the Blon logo is added. Its tuning is more of a Harman-ish one which has a leaner U-shaped sound signature. It has more emphasis on the sub bass, a tad recessed, spare note weight and transparent midrange presentation and a more accentuated upper mids to presence treble region which makes a contrasting sonic profile with Z300. The profile of the two is not the same, with much more light, transparency and clarity in the C3s. While the Z300s are characterised by a clear veil and a feeling of darkness. Comparing the two graphics, the differences are clear. While the low end has similarities, the C3's bass is cleaner, slightly more visceral and better executed, with more resolution, definition, a cleaner and clearer punch, as well as a more discernible texture. It is clear that the difference in light is also noticeable in the bass. You even feel that the bass is faster and more concise in the C3s. Are the WGZBLON x HBB Z300 the warm and dark version of the TinHiFi C3? They could be, but they are also less detailed and soft, veiled, even nuanced. Only in their weight and build level could they be superior. But to each his own. You might also think that the C3s can be a bit excessive and tiring in some cases. All in all, i prefer musicality of Z300, but at 2 times the price of the Simgot, it doesn't really impress technical performance wise.Treble​The treble is leaning slightly towards dark without losing ground too much from the bass. It does have enough contrasting energy to provide decent amount of details without being piercing or sibilant. It does have adequate extension and air up top, but not fantastic. However, treble is definitely not the main focus here and I doubt this will affect the listening enjoyment that much. Midrange​There are a fair amount of bleed from midbass into the mids, but not to a degree where it affects the listening experience. Vocals do suffer a bit here, especially with female vocals. Male vocals fare better with quite an oomph whenever the right low notes are hit. I personally like vocal jazz with the Z300 here, something like "Hajimete no Chuu" by Platina Jazz feat. Niklas Gabrielsson. This is, again, another example of genre specificity that Z300 excels in. The vocal presentation is very clean, but male vocals sound a bit thin to my ears. However, female vocals are really enjoyable on the EM6L. In fact, I would say that female vocals sound even better on this than on the Xenns Top. Meaning there is a guilty pleasure that HBB was going for a night-out-on-the-town, style of sinfulness. Such an IEM tonal choice exemplifies mood and musicality, offering note-weight and smoothness which by itself conquers many a subtle issue.

As for its tonality and sonic profile, BLON Z300 is a warm, V-shaped sound signature with boosted bass, recessed midrange and just a slightly elevated treble region particularly on the upper-mids up to the presence part. The stage set is effectively organised and constructed, and it is both wide and far. The notes' distant and distinct characteristics make them easy to distinguish, so the separation is really nice. Even though the imaging could be sharper, I still think it is better than the Piccolo and the Khan and can bring clarity to the mix. Featuring a state-of-the-art 10mm silicone diaphragm, BLON Z300 is ensured with superior audio performance. The diaphragm's unique composition allows it to deliver clear and natural sound that is both accurate and dynamic. When it comes to technical capabilities, EW100P has an edge as it has average sound/speaker stage and better separation and layering. Even detail retrieval on EW100P is even better than Z300.You can see how weak the bass is on the z 4, if you like bass it's hard for the z 4 to compete with the z300 the z 300 is not as successful as the bl 03, it is still a successful model. I was not very impressed with the sound character, but I was impressed by the appearance. If you're looking for a fun and well-built iems in the price range, the z 300 is a good choice. If you are looking for a more detailed model, I recommend you to evaluate different options. I tried the phone on different sources, which are: iPhone SE (my “DAP”), Dell Laptop, Apple Dongle, Truthear Shio, Cayin RU6 , Topping G5 and Topping DX3 Pro+. Here’s the graph of the Tripowin Piccolo. It looks pretty similar to the Z300 doesn’t it? They do sound different though, with the Z300 being preferable to my ears. One interesting thing I want to point out is that 2 kHz and 4 kHz humps. A lot of older ChiFi IEMs had this hump at these two points and a dip at 3 kHz. We can see a remnant of that here, even if it’s quite minor.

Moving on to the mid range, I find that acoustic guitars and other similar instruments have a nice timbre to them, seeming very realistic with just a hint of extra warmth. The lower ranges of vocals, particularly deep male vocals such as Leonard Cohen in “ Happens to the Heart” have a nice smoothness in the lower mids, with a decent amount of detail. iFi Hipdac - Because of the aggressive forwardness of the vocals and the instruments' attempts to respond more sharply, the treble becomes reserved and slightly dull when paired with the Hipdac, while the midrange completely takes over as the mix's main star. In the mix, the bass is given more prominence, and the mid-bass response may even increase. Except for the stage becoming a little bit smaller, I didn't notice any changes to the technical performance. Although this pairing provided a fun and exciting response, I still prefer V6 pairing to the Hipdac. BLON advertises that the shells are fashioned from 18K gold-plated zinc alloy, and build-wise, they are absolutely solid, with the housings akin to a tank. In fact, due to these metal furnishings, the earpieces are quite heavy. Even though ergonomics are excellent, the heavy shells may unfortunately add to fatigue during longer listening sessions.It is a bloodbath when comparing the Z300 against its predecessor, the Z200. Firstly, the Z200 has non-detachable cables, which may be a deal-breaker for some. I am thankful to HBB himself and the kind staff at Linsoul for setting up this unit for review. The same is true for this evaluation as it has been for all of my evaluations: all of the ideas I've discussed below are wholly my own, original thoughts that haven't been influenced by anyone. If interested, go to this link. The trebles on the EM6L are really well extended. They are very airy and detailed. However, the detailed trebles come with their cons too. As such, the EM6L is a bit sibilant. It also doesn't compare to the Xenns Top, which has very well extended, extremely detailed, and quality trebles but presents them in a controlled and smooth manner. Hence, it is not fatiguing or overwhelming during long sessions. The Top also has better technicality and separations than the EM6L or the Khan by a huge margin (understandably as they belong in different price ratios). So the trebles sound better on the Xenns Top. The EM6L sometimes sounds fatiguing and piercing with treble-heavy songs. But it is in the mids where the difference between the two is most apparent. The graph reveals this. While the Z300s are warm and dense, the C3s are clearer, more transparent and energetic. Their sound is brighter and cleaner, details are more perceptible. Male vocals feel less lively on the Z300s, slightly more recessed. The liveliness of the C3s is more forward, revealing a greater amount of nuance, giving a more natural and accurate timbre, although it is also thinner and more delicate. The harmonic quality is more remarkable in the TinHiFi. And this is also noticeable in the female voices. They, on the Z300s, are not able to stand out with the level of presence, clarity and transparency that they do on the C3s.
