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).Current favorites:IEM fav: [ 7Hz Timeless / Salnotes Zero | Tangzu Wu Zetian | qdc Anole VX | Softears RSV | UM MEST MkII | ThieAudio Monarch | Moondrop Variations | DUNU Studio SA6 | Moondrop Kato / Dusk | XENNS Mangird Tea | TRUTHEAR HEXA | See Audio Bravery | FiiO FHE | Moondrop Stellaris | GeekWold GK10 | TRI Starsea / i3 Pro | Moondrop Aria(mod) / Chu | KBEAR Believe | KZ ZAS | DQ6S | Tripowin Lea ]Wireless fav: [AKG N5005 / N400 | AirPodsPro | Nekocake | Gamer No.1 ]Fullsize-Can fav: [ HD560S / HD650 / Unipolar 2002 / HD25 | Yamaha HP-1 | AKG K340 | DT990PRO[600Ω] ]DAP/DAC fav: L&P W2 | FiiO M11Pro/BTR5/3K | HifiMan HM801 | Astel&Kern AK70 |Speaker: AMG Burmester SystemShelved items(benched roaster):IE8 / MXW1 / Momentum OE / HD414 / HD202 / PX100 / CX95 / MX90VC / OMX90VC / MX760/660/500 /HD450BT| K701 / K530LTD / K450 / K171MKII /K24&26P/ IP2 / K314P / K324P / K12P | JVC HP-FX500 | Moondrop Blessing 2/ Starfield / KXXS / Quarks / ShiroYuki / Nameless | See Audio Yume | GeekWold GK3 | NF Audio NM2+ | KZ ZST Pro / ZS5 / ZS10 / ZS10Pro / ZSN / ZSN ProX/ AS10 / AS12 / AS16 / ASX / AST / DQ6 / ZAX / EDX / S1D / SKS / Z1Pro / ZEX/ NRA/ZEX Pro/ T10 /SKS /SK10 | CCA CS10 / C10 Pro / CA16 / CS16 / CRN | Tripowin Mele | OpenHeart Resin | HZSound Heart Mirror | Final E500/E1000/VR3000| TRI i3 Pro | JadeAudio EA3 | Thie Audio Legacy 3 | KBEAR Stellar / KS1 / KS2 /Lark 4K / Neon / Robin | TRN VX(w/BT20ProTWS) / MT1 / VX PRO | NICEHCK DB3 | QKZ VK1 / VK3 / VK4 / KD4 / KD7 / CK3 / CK7 / CK9 | CCZ Plume/Coffee Bean DC-01 | Audio Technica ESW9 / EW9 / ANC7 | Koss PRO4AA / PortaPro / KSC75 / KSC35 / Spark Plug | V-moda Bassfreq | ER4S / ER2SE | GS Audio ST10 /GT12 | Bang&Olufsen A8 | Klipsch Custom2 | Harman Kardon EP720 | UE TF10PRO / 5EB / Superfi 5 | Sony: EXQ1 /EX90LP / EX700ST | Westone 4/ UM2 | Ultrasone DJ1PRO | Surplex HD668B/HD661 | HPM1000 | JBL Reference410 | Yamaha YH-100 | Fostex T50RP | Grado SR225 | TEAC HP102 | Goldring GR-104 | STAX SR40 | Phillips SHE9700 /SHP8500 | Marantz HP101|Lexus Mark Levinson========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 timeOld 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 nozzleNew 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 nozzleVS 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-inNote:-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, PercussioninstLark 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!

I’m slim 5’6” and I have the most small ear canals. For airpods pro I use either extra small or small. And this tips for good. I like the sound quality as well. It sounds crispier than other earbuds. And boy the mic is really good. I bought apple wired earbuds last time and actually recorded and compared both earbuds, and this one sounds more deeper and closer to the mic. Lastly I was worried if the earbuds might be to big and look weird, especially I have a small face among men. And this actually isn’t that big and doesn’t look weird that I wouldn’t mind using this in nyc cafe.

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.

Sound is great for the price. I've used these side by side with shure 215 and the differences were minimal. I would totally recommend these for a first set or a back up set for someone.

These strike a niche that isn't filled that often at this price point. A better than average cable plus a legitimately usable case. Ear tips are OK, wish they left out the second set and thew in a pair of foams. Onto the sound: good punchy bass, neutral mids, highs are ever so slightly pronounced. I say throw up the bass half a db and drop the highs 1.5 db. That'll make em slightly bass leaning and flat across. If you like bright sound this does it well.

Media control and mic broke after a week, but these are still rly good iems for people on a budget

For a pair of headphones this inexpensive they are worth it to maybe even more than worth it. I would easily compare these to an old pair of 100$ Bose in-ear headphones. The wrap around the ear is comfortable and not noticeable, the cable smooth and not rubbery letting them move easily across clothing, but the braiding gives grip. The 90 degree plug is a huge boon to up the ergonomic factor. Overall if you need a pair of headphones and don't want to spend big bucks, get these.

The first thing I will mention about these IEMs is that the cable that they come with is bad, very bad. At first, I thought these IEMs were one of the worst I've heard. There was no instrument separation, shrieking highs and bloated bass. I decided to replace the cable with a 8 core TRN cable and these IEMs really came to life. Instruments came across cleanly and there was more balanced frequency response. So if you're considering these, be prepared to shell out for a better cable.These have a V shaped response so bass and treble are slightly more pronounced, but not overly so. The mids are still very present and clear. Because of the V shaped frequency response, these are suited more for genres like Pop and EDM. They're ok for instrumental genres, but I usually go for IEMs with a flat response for those.I also changed out the stock tips for KZ Starline tips that were a tad more comfortable for me. The stock tips aren't bad, I just like Starlines for most of my IEms.Overall, I would say if you use these IEMs as they come, they're a 2 star purchase at best. However, swap out the cable and you have quite a capable pair of IEMs for V-shaped sound suitable for Pop or EDM. One star deduction for the awful included cable.One more note: The product description says noise canceling. These are not active noise canceling IEMs. They do drown out some noise due to isolation (having your ears plugged by the tips), but don't actually contain any noise canceling circuitry.

Tiene un sonido bien balanceado, la calidad como tal es buena por el precio y son cómodos. La única desventaja que encontré es que en el modelo con micrófono este queda un poco lejos y a veces no se me escuchaba fuerte y claro. Fuera de eso no tengo ninguna queja, buenos audífonos

Muy buenos , soy de usarlos mucho y de manera ruda y han resistido mucho

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.

Estos cascos se los compre a mi mujer que hace stream en twitch, ella tenia cascos gamer de 120 euros de marca logitech, y esta encantada con estos ya que suenan genial y además son infinitamente mas cómodos los recomiendo al 100%

Incredibile! è questa la parola che continuavo a ripetermi quando le provavo per la prima volta! Ci sono diverse cose che mi hanno stupito comprando queste cuffie: per primo la vestibilità. Credevo che fossero come delle normali in ear, se non peggio, che mi tappassero l'orecchio, pesanti al limite di poterle usare per anche pochi minuti! niente di tutto ciò: sono comodissime, il che ancora mi sembra strano! sarà perchè forse il peso si bilancia o non so per quale motivo ma quando le metti dopo un pò te ne dimentichi di averle...però ti ricordi di averle indossate per il secondo motivo di stupore, ovvero il loro compito principale, cioè quando suonano! come è possibile che un paio di cuffie così a poco prezzo si possano paragonare ad altre che costano 10 volte tanto? incredibile la resa sonora che danno! Io non sono audiofilo ne un esperto di settaggi, però se voglio dar importanza a ciò che ascolto, uso queste cuffie! Per prima cosa, se cambi le frequenze, cambia anche il suono...il che sembra banale e stupido, ma non lo è! Paragonando ad altri prodotti della stessa fascia di prezzo (normali cuffiette anche per telefoni), hanno totalmente un altra risposta. le cuffie normali sembra quasi non cambi il suono indipendentemente dall'equalizzazione , su queste invece cambia tutto! mi spiace non avere un parare da persona esperta ma anche quella gente non esperta come me, sentirà che il prodotto è davvero buono e di qualità! ottimi bassi e buon microfono anche nelle chiamate! speriamo durino tanto perchè sono una soddisfazione! consigliate!
