Product Information

E3000 is better if you want a more relaxing and warmer sound, while being more natural. KS2 is better for a more fun sound.

Upon first listen on the KS2’s, the bass immediately stood out. It was like I was discovering car subwoofers again, the surprise on my face definitely showed, there’s no way I was keeping a pokerface when it came to the KS2’s bass.With this respect, those looking towards a more natural timbre for live and unplug playlist would have to explore other options. Live performances can still be enjoyable with the KS2, if we’re open to the different flavours that iems in general deliver. Build: The entire IEM shell is plastic with the ever-popular pseudo-custom shape. It does look and feel fragile, even though the finish in general is pretty good for the price (cutouts are precise, vents are well drilled, shell-joints are smooth). The nozzle is metal fortunately and has an angled lip to grip onto tips along with facilitating a secure fit. OK, let’s cut the crap right away. This earphone is not for the gallery, it is not sexy, it features a generic design. No staged photos, no camouflaged sales brochure, no other window dressing required to stimulate buying appetite. The KBEAR KS2 is all about functionality: sound and fit – and value. Apparently, 70% of the cost are in the drivers. It is KBEAR’s lowest priced budget model. As you know, KBEAR is a brand that has come a long way in the last half year with their popular Diamond and KB04 models both tuned with the help of KopiOkaya and myself – two big-hearted however poor pro-bono amateur tuners who made these products fly off the shelves like hotcakes. The KBEAR KS2 were apparently tuned by a professional team. KS1’s treble is crisp with a hint of sparkle. Yet it’s non-fatiguing and maintains good energy throughout. Detail retrieval is quite impressive considering the earphone’s warm tone and budget price. The treble is lively and precise and it achieves that without any sibilance or shrillness. It’s really a pretty impressive quality treble for a budget IEM. Soundstage

The mids and highs are tuned quite well and they are the highlight of this IEM. The BA excels in delivering sibilance free highs with sufficient details. Vocals are fleshed out well – neither too forward nor recessed. There is some bass bleed into the lower mids, and it is noticeable, but not so pronounced to cause annoyance. On the other hand, the difference with these average headphones will not be too much as to become an earphone that could be used in libraries. 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. The star of the KBEAR KS2 is undoubtedly the huge soundstage. It is very impressive in all dimensions and gives you the feeling you are at a live concert – when listening to a live recording, of course. Cavernous but not hollow! In this respect, it beats many more expensive competitors. Detail resolution is equally impressive: I felt I was diving through a symphony orchestra when listening to Gustavo Dudamel’s/LA Symphonic’s Star Wars interpretations. All of the above point to the KBEAR KS2’s good suitability for gaming. Blon BL-03(mesh mod): Treble quantity is similar, but extension and air are better on the 03 and it sounds much more natural.KB04 is less V shaped as per the graphs below, with lesser bass and upper mids/lower treble. Note weight on the KB04 is slightly thinner, but the KB04 is more balanced tonally. The KB04 also has slightly better instrument timbre. Firstly, the over ear cable design is different to the original cabled version, it’s rubberier in texture and flops around on the top of your ear, and constantly requires adjustment. CONCLUSION: Music is pleasant, good for electronic without too much punch, video and film given the well expressed mids. Definitely not suitable for sound engineers, but given the low price they are a great deal for those who want to listen to music in a decent way. Attachments A very mixed review for both the KBEAR KS2 Earphones and the KBEAR S1 Bluetooth Cable. I love the audio quality of the earphones, but the original cable’s multi-function control button is quite limiting. Upgrading to the Bluetooth cable improves the user experience in terms of control but creates more nuisance in terms of poor audio quality. Female-vocals: Hiroyuki Sawano – OldToday (01:25-01:52) the vocals are pretty average in how natural they are (for hybrids), but the issue is that it is recessed where it should be more forward (although not more forward than the instruments more like it needs to be in the middle).

Within the same brand and similar profile, KBEAR has presented two slightly different tunings: A brighter, more defined and somewhat more classic profile for the KB04. While for the KS2, my opinion is that they wanted to create a more U-shaped IEMS, giving more energy to the lower end, softening the mids and highs, to create a more relaxed sound, not so explicit and less persistent, which offers a more obvious emphasis on recreating a larger and more open scene, not on the details.Due to their construction, their weight is very light, which makes them very pleasant IEMS for continuous and daily use. Being tuned by the same tuner as Blon-03, the KS2 have a bright balanced signature, which is mids-light/treble-heavy, coupled with a jewel of a sound-stage! Imaging and staging is exceptional (just as Jürgen had mentioned in his first impressions)… BUT I am not entirely impressed by it and here is why: All in all, I feel that build, fit, and comfort are quite decent and there’s nothing that would put me off in this department. So let’s move to the most important part of The cable is a standard 4 core braided type similar to that supplied by KZ with a chunky plastic Y-split and no chin slider and is thus prone to tangling. The connectors are a 2-pin angled and hooded type with short pins and the termination is a 3.5 mm right angled plastic plug.
