Product Information

The KBear KS2 is a shining example of high performance, can come in surprisingly affordable price tag. Sure, the KS2 is not exactly your dream top-of-the-line flagship killer iem (though it could be for some) BUT it does well in quite a few aspects. And that’s no small feat. Bass is a tad too much for my taste… HOWEVER, it is clean, fast, punchy bass. Not muddy or wooly. Great for EDM stuff. TREBLES: Although there are no particular hisses or excesses generated by the balanced armature in the output nozzle, the highs are a bit confused and poorly controlled, especially in the frequencies between 4k and 8k there is a lot of confusion. That’s one more reason why drummers will not love this headset: the charlestones are a bit of a slap and the bass drums do not explode as they should (don't try listening to Dream Theater, you will cry). What did a member of our Facebook group tell me: “Don’t tell us it’s got a long trunk, fat legs, and rough brown skin. Tell us instead it’s an elephant!” And this elephant is big. BIIIIIG…biggest soundstage in all dimensions I could imagine: deep, wide, and tall. Seriously, it is gigantic. You feel you are in a huge cave and the music was recorded binaurally. The signature can be described as warm-fun-lively V-shape with a tad of plastic added (not too bad, though). Here you have it. That’s what your elephant looks like. KS1’s shells are identical to those of the KBEAR KS2. The moulded acrylic shells are lightweight but feel durable and should have good longevity. There are 2 vents, both on the inner side of the shell. KBEAR have kept the visual elements fairly simple with just a small logo placed on the faceplates.

At this point of the review you’ll probably expect me to love this KBEAR S1 Bluetooth cable. But, I don’t. Good day! After 4 days of casual and critical listening, here’s my written review for the KB Ear KS2. A budget basshead’s dream! Just received the KBEAR KS2. First impression… Better than Moondrop SSR… That’s a good start… Definitely better than TRN M10… That’s another good start.The KBEAR KS2 is a warm-fun-lively V-shaped earphone that excels by its gigantic soundstage in all dimensions at the price of recessed mids. Sound analysis was done using my Fiio M15, Shanling M6 pro, M5s, M3s, Ibasso DX160 and the Sony ZX300. The KS2 was burned in for a total of 150 hours before evaluation.

Lows: A lot of more sub-bass than mid-bass. The bass isn’t that tight nor loose and the speed is pretty average. It isn’t muddying the sound though because of the low mid-bass quantity. I don’t think the KS2 is a class leader in any way, but that doesn’t really matter when it is inexpensive, sounds good, and should provide users with plenty of entertainment. Plus, it can match and possibly exceed the performance of the MS1 – Rainbow at a third of the cost (read about that in my early impressions post), so good on KB EAR for that.

This is where I wished the KS2 had a bit less treble energy. Reality is when you're out and about the ample bass end is a good choice but external noise has a tendency to drown out bass notes first. Not so much the treble end. So that is when you're gonna hear a lot of treble. In a less noisy environment the bass comes in loud and clear. Final Audio E3000: Treble quantity is lower on the E3000 but sounds more natural, although the KS2 has better extension and is airier.

The capsules mount the two-pin connection, 0.78mm, on a transparent plastic plate, which protrudes a little over a mm, from the body of the IEMS.This leaves you to fully enjoy your music in a total immersive feeling. They’re also amazingly comfortable to use and even after wearing for several hours they’re still as comfortable as when you first inserted them. Sound Quality. The KS2 housing appears to be plastic in nature given how they look and feel. The housing appears fairly sturdy and stands up to daily casual use. A small air vent is located on the inner side of the housing (just above the large 10mm Dynamic driver is located) where the ear concha is located. The nozzle is a fine looking gold coloured aluminium alloy. Given its price point, this is quite a bonus in terms of built quality. 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. KBEAR started their journey off on the wrong foot. From the horrible Opal (which I couldn't be bothered to review, as it should be erased from history) to the very restrictive F1, it seemed that KBEAR won't make it too far before vanishing from existance in the crowded earphones market.
