The included cable is the upgraded 4-core KZ silver plated copper version. It handles quite well and is less prone to tangling than the older brown cable in my experience. At the top are the hooded, transparent 2-pin connector housings, followed by heat-shrink pre-formed ear guides. Like the KS1, the BL-01 has a warm V-shaped tuning with a mid-bass emphasis, recessed mids and average detail retrieval, but a believable natural timbre. In this respect it resembles the earlier, similar-sounding BL-03. The bass has a mid bass emphasis and is slower than that of the KS1 which has a better transient response. The mids are more recessed than the KS1, but the treble on the two is quite similar. The KS1 achieves a much better fit than the BLON which is problematic with its very short nozzles and poor cable, although the build quality is superior. The more even response of the KS1 just nudges it ahead for me.

Between the 2 sets, the BLON BL-01 is probably a tinge better in sound (if amped), but the fitting issues and the need for a higher powered source would mean I would give my recommendation to the KBEAR KS1, unless you have a good amp on hand. The treble is also enhanced by the wide sense of space which the tuning of the KS1 gives one. The presentation being analogue type harmonic tuning, gives you the sense of being surrounded by the music, quite expansive and enveloping. Bring him Home", from "Les Miserables" received a heart-warming performance from The Piano Guys. The timbre of the cello and piano was very authentic. The effect was perhaps a little larger than life in the lower notes, but the emotion and feeling of the piece was conveyed most effectively, with the two instruments both contrasting and complementing each other. This kind of material was perfect for the KS1. I highly recommend this pair to those starting out. It is a great pair to see where your preferences lie. For less than the price of most cables on the market you can get a taste of a great Soundstage. String instruments sound fantastic. Listen to with these to Father and Son by Cat Stevens. Piano sound great too, shout out to Ru's Piano on youtube.

Removable Cable & Ealuminum Alloy Nozzle】4 strands of 6N OFC high-quality wires not only effectively improve the transparency, separation, sound field, making the sound bottom crystal clear, vocals and musical instruments are more beautiful and beautiful, but also reduce signal transmission lost. Exchangeable 2PIN wire design improves the playability. and a limit slot is added to extend the life of the headset. KBEAR KS2 adopts aluminum alloy nozzle, which making the mid-bass clean and smooth. Soundstage is another great aspect of the ks2 , with depth bright deep and as well as height reaching a nice height. Width is good not the widest I've heard but the compressed either .imaging is great as well.

In this new version, the KZ overlords have made the midrange more forward than it was on the original ZSN Pro. This was achieved not so much by boosting the mids but by slightly attenuating the bass (compared to the older models). I did not get any 3D imaging from these earphones, mostly just sounds from either the left or right earphones. The KBear KS1 is a decent set of earphones, but unfortunately there is almost nothing special to talk about, a bit too safe for my liking. You won’t go wrong starting with this (a safe mainstream tuning with all the standard bells and whistles), but you have better options if you’re looking for a second pair to own. The QC issues I see in various forums also makes me prevent a full recommendation, so if you’re gonna buy one, beware. The first thing I noticed about the Pro X highs was that the treble is noticeably smoother and more even than the old Pro. This is a sweeter, wetter sound than the scratchy KZ treble of old and it makes a big difference in the overall audio quality. The nozzles are aluminium with a protective mesh cover and once again, we see the Type-C slotted 2-pin plug. Just like the KS2, I find the KS1 shells to be very comfortable and have no trouble keeping them in my ears for hours at a time. Passive noise isolation is average for this type of shell which means KS1 is quite good for commuting and for use in noisy public spaces. CableSoundwise, let's say that this IEM plays just a bit above of its price point, but it's not very much asking. Punchy bass that will satisfy those listening to modern music genres or liking a (very) V-shape sound signature. Mediums are way too recessed for my taste. Treble is ok, with a decent extension, it can become a bit aggressive at times, especially if the recording calls for it, but nothing really bad here. The sound out of the box is… bad! These need 72 hours of burn in with very bass heavy music at loud volume. If you ever want to experience the magic of burn in, buy these IEM’s! The KZ ZST X (review here) has the same dual-driver configuration as the KZ ZSN Pro X. It has a very similar tuning but with less treble emphasis. Of course, the different shape and materials of the acrylic housings make a difference too, but it’s still clear these are of the same ilk. When I first saw the “KBEAR” branding, I pictured a bear wearing earphones. But it’s not an animal— KB Ear (as it’s actually styled) is a Chinese earphone maker who has launched a number of entry-level and mid-fi choices to the in-ear market in recent months.

Treble is most definitely elevated. It does not create sibilance in my experience but will definitely reproduce any sibilance present in the original mix. If its a bit too bright, try using tips with a smaller bore to even things out. I like the sound these make when the treble is tamed slightly. The mids start to really pop out. I did find them a bit fatiguing to use for long periods of time and often found myself eyeing up my collection of over-ears and more relaxed in-ear IEMs. This is more personal though, and was correct after moving to foam tips and applying a bit of equalization. Finally, the treble is inoffensive. It’s just there to make sure that things don’t sound overly dark but it takes the furthest seat in the entire presentation. Cymbals hits sound muted, they easily smear into each other, and there is hints of splashiness despite the recessed treble. It doesn’t draw much attention to it, but when you pay attention to the treble — it’s not good in terms of resolution/timbre. Soundstage, Imaging and Separation: The soundstaging is a bit below average, feels like a tight space. It's not long since KBEAR released their excellent KB04 hybrid which could be described as a "Diamond Lite". It delivered a good proportion of the Diamond's performance at a fraction of the cost. Now we have another 1DD + 1BA hybrid at an even lower price, the KS2.Conclusion: This IEM was not a bad attempt by KBEAR but I also wouldn't say its the best. Still, the KS2 is a great IEM in its price range. If you have spare cash lying around on the floor, you should try to get you hands on it. Separation is good, with well-defined spatial positions, but the cramped soundstage prevents it on getting its full potential. Did you fully understand that? Right. Let’s move on and we’ll see for ourselves in the part on sound how this budget IEM performs. Although somewhat recessed, the midrange was still articulate with a somewhat warmish cast in the lower region deriving from the mid bass and it became brighter towards the boundary with the treble. Generally the timbre was natural and with a good transient response. I did touch on imaging a bit earlier, and the term “muddy” is still best to describe it. Instrumentation is difficult to place outside of left and right channel, and the clashing of frequencies with the bass overly exaggerate the V-Shaped frequency response.
