About myself:
======START OF INTRODUCTION ======
Audio equipment reviewer over 20year+ of experience in headphones/earphones/IEM/DAP, initially motivated by Sennheiser/AKG.
After spending a decade with full-size headphones, home audio speakers, I shifted my main listening environment to IEM (100+ personal inventories ).
On mobile, I havingLexus’s Mark Levision system, and moved to Mercedes AMG’s Burmester 3D System.
I have been a member & reviewer at headfi.org —one of the most diversified international audio equipment enthusiast community— since 2008, have 100+ IEMs/50+ full size cans/numerous DAPs.
Currently enjoying 7Hz Timeless, Softears RSV, Moondrop’s Blessing 2, Blessing 2 dusk, Variations, Aria, Kato, as well as many other current market gatekeepers such as qdc anole VX ($2900USD), UM MEST MKII ($1,600), Thieaudio Monarch ($760), DUNU SA6 ($560), besides rather old-school Sennheiser/ Shure/ Westone/Sony/AudioTechnica/AKG/Etymotic Researchms IEMs (these established consumer manufacturers are no longer making competitive cost-to-performance IEMs at current market of 2022, except very selective few ones from Sony).

========END OF INTRODUCTION======
About Lark:
-Stock ear tip, came with dark and clear silicon, tried M size but it was too V-shaped to me so I changed to L size tip
-1 KBEar customized BA in the nozzle, 1 x 10mm DD
-Sound stage on the narrower side due to its main treble source is the BA placed in its nozzle, but the positive trade-off will be good and “direct” sound pressure that helps to create better imaging and sound textures.
-Sound is in-the-head type except for bass range, this would help vocals to stay forward without interruptions
-Very cooler side of tuning with W-shape on mid-bass and 8k peak and slight 4k peak resulting clear and energetic sound presentation, female vocal gets elevated as a result of this tuning
-Bass range is pretty neutral and flat, nicely balanced! No bleeding into mids.
-8k peak brings good sparkles, yet not too fatiguing, very nicely tuned from a single BA!
-Needs some power to drive compared to similar 1BA+1DD type hybrids
-Coherence / linear phasing: TBD needs some time
Old pre Oct 2020 model (“4k model” vs New Post-Oct 2020 model:
KB LARK new model after 12 hours of burn-in:
-mellower thus softer tone, sound injection is more direct than old 4k version
-may work for someone who found former lark to be too edgy, it’s 4khz peak is nerfed and the tone is very welcoming, again a surprise from KBEAR after Tri Starsea. They got skills to fine-tune IEMs, even if it’s sub$30 model, it sounds very premium, not a typical Bellsing grainy tone. Piano sounds flawless.
Out of box impression vs original Lark was not that impressive, but now even after 12 hours of burn-in, thing changed. Muddy bass is gone and thus soft and warm yet very detail retrieving neutral tuning come to alive, some coloring in mid range, a very very soft veiling, I’d say it reminds me of mid range of Moondrop blessing2’s tuning.
vs old Lark:
-old Lark has 3-4khz peak which works for critical listening for detail retrieval for upper-mid, lower-treble, but in a long run it may cause some exhaustion, new Lark nerfed 4khz, remained 3khz peak, which relieved exhaustion factor yet some technical listeners may find lack of definition (studio monitor vs easy listening)
Afterall, this is very recommendable to someone looking for neutral and gentle fine-tuned budget option! Low Gain mode is recommended, this thing explodes with most of amp’s high gain and lose its delicacy.
used stock tip & cable, everything works just fine.
which version is your lark?
4k old version(pre Oct 2020)
-has no yellow thing around acoustic white filter
-BA is located on the edge of nozzle
New version (post Oct 2020)
-has yellow thing (manufacturer’s mod to nerf 4khz) on the acoustic filter
-BA is located at the center of the nozzle
VS CCA CSN
-CSN is on warmer and slightly tamed W-shape tuning, wider sound stage
-Lark is more on detail retrieval focus compared to CSN
-CSN/DQ6’s XUN driver seemed is a better-textured bass range driver there, although Lark bass driver needs a burn-in
Note:
-The W shape tonality reminds me of UM MEST MkII, although MEST MKII gets its third peak around 6k, vs Lark 8k, I may refer Lark as a grandson of MEST MKII less sound stage. Both good at fun and energetic music reproduction.
-Good at Rock with vocals / Percussions / any upbeat music that does not require sound stage / Jazz trio
-If you like beyerdynamic headphones this one pretty much would fit your flavor, pretty Dry x Fast x Clean x Energetic!
[Not For] bassheads and/or bassists, baritone oriented players, for those CCA CSN does better on bass line in terms of quantity
[For] Vocalists, Percussioninst
Lark pretty much plays my favorite Yorushika song at top tier among all of my 100+ IEM collections which includes many contenders, that’s quite a statement!

Good design, passible sound
The KS2s are light and snug due to the shape of their smooth plastic housing, but the way they sound is just ok. Out of the box, they have a far too v-shaped sound profile. The bass feels more present than it should and the top end felt jarring while listening to certain songs. I had to mess around with my equalizer for a while in order to get them to sound good.
I really can’t complain much because these are only around 20 bucks after all, and even their ok sound has surpassed most headphones in their price range. I’m giving it four stars because of their value and comfort.

Wireless adapter not included.
I like the weight and feel around/on ear. Sounds are good for the price.
One of the main feature I was looking into was having a wired/wireless combo so I could go wireless whenever I needed. Looked at the specs and the connection there says wired/wireless. Get the box – realize theres no way to go wireless unless you get an adapter. Wish I had known that, would’ve looked for an alternative or bought the adapter at the time.

Buenos Audifonos
Estos audífonos son buenos y el precio excelente calidad precio, estoy satisfecho con ellos👍

These IEMs sound great for the price, fit well, and are overall a great buy. Probably one of the best ~$20 chi-fi sets you can buy, along with KZ ZSNs and a few others. These fit better than the ZSNs, as they are better shaped to an actual human ear, instead of some odd sharp angle. I’d describe the soundstage as wide enough, and a slight V shape, with more pronounced bass than treble. Packaging was great, with little waste and proper presentation. The supplied cable seems better built and thought out than other chi-fi sets, as the area where the cable forks is built sturdier, and shouldn’t bend and break like other KZ sets.
I do have a couple cons to take note of:
The area where the ear hooks make contact to the actual IEMs seems rather poorly enforced, on both buds the points of contact creak when minor force is applied inwards or outwards by hand. This does not affect the listening experience whatsoever.
On the 3.5mm connector, my unit came out of the box with a minor chip in the metal. This doesn’t change the performance of the unit in any way, but it does leave a bad impression.
Other than that, this is a solid IEM I’d recommend.

Für den Preis sind die Kopfhörer zufriedenstellend. Sie haben einen ordentlichen Bassklang und sind somit eher für EDM und weniger für Vokal fokussierte Tracks.

Bom perfeito
