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!

These work great for long meetings or gaming sessions. The mic works great, especially during work calls/ online meetings. Clear sound. Attractive. Cord length is adequate. Connects easily. I love that they come with a carrying case. Fit comfortably in my ear, even during long sessions.

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.

They sound GREAT -- I've heard new sounds in songs I've played for months. They're comfy (I can wear them for hours with my glasses on). The button function is simple and useful. Could not be happier.

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.

just do yourself a favor and get these , i’ve had these for about 2 YEARS now . The sound quality is amazing +the comfort they bring on your ear. If you work often on a PC/Laptop just get them.I think the cable is starting to fail but thats kinda my fault im clumsy w my hands😂 definitely gonna repurchase

Had the first set by these guys and they were heavy bass and these are brighter, more comfortable and they seem like they will be a durable product that creates amazing tone .. Cant go wrong with these

I use these IEMs while singing with my church's praise team. The sound quality is good and allows good distinction of sounds without distortion or static. Connecting the wire to each ear bud was easy in comparison the other brand I had. I've not had any issues with them disconnecting. I also like the copper cord since it is more inconspicuous with colored clothing. The length of the cord is long enough to run down the back of my shirt and into the pack on my waistband. I am satisfied with this product and would buy them again.
