Amazing for price
Good noise blocking, sound good. Can be a little bit uncomfortable if you wear glasses but depends on the glasses being worn.

I was blown away!
I've been in the market to get a new set of headphones for a while now since my usual ones are discontinued and thus very difficult (and getting more expensive) to find. I hadn't thought of getting earbuds again because they tend to be very tinny, they fall out of my ears and honestly they're a nasty experience to me, I swapped to proper over ear headphones years ago and never looked back.But these ones kept being recommended to me. First a friend who had them kept going on about them, then I saw them again from a youtuber I watch (waddup Dankpods) and he raves about these things a lot, so I thought fine, I'll grab a pair along with the new headset I was getting, they're cheap and if they're any decent they can be my backup pair.I was absolutely blown away by how good they sound. These things are legit. I rarely use the headphones I bought (which were three times the price btw!) because these are just so good! They're not professional quality by any means and they take a bit to get used to in your ears if you're not used to them being plugged, but holy heck! The sound quality is great, you can actually hear a decent amount of bass in those dirtier songs and everything is just solid.The only downpoint I have about these is they've made me super paranoid about cleaning out my ears, because I fear being in a public space, pulling one out and them just being covered in earwax.

KBEAR KS1 type c. Excellent 👍
Wired version of these still going strong a few years(one of my favourite IEMs) later but needed Type C after phone upgrade( USB-C iPhone)Working absolutely perfectly, and sound great.In line remote working fine.Perfect for my needs and a great little set of IEMs without breaking the bank 🙂

Good snug fitting
Great fitting earphones nice and snug in your ear. My only criticism of them is they lack good bass response great on top end and mid but not much bass, I use these for on stage monitoring bit disappointed.

Very impressive for the money
I have several pairs of IEMs, all Chi-Fi and in the sub £100 category, but I wanted a pair of IEMS for gaming (on a PS5 and PC).These were cheap, so I kept my expectations low. They didn't have to be high-end sounding, they just had to be "good enough" for gaming.Compared to my other IEMS these are crisper, more treble, brighter sounding (only by a little mind you) but damn, they sound good to me. I really like the way they're tuned for music and for gaming. Despite not getting them for music I really like the way these sound and prefer these over my other pairs, (One of my IEMs was more than 2x the price as well). Probably don't get them if you're a basshead though - these aren't tuned that way.Oh and they sound great in gaming as well.The only criticism is that the cable is a bit short. It's fine for sticking into a Dualsense controller, but a little bit short for plugging into either of my DACs or the monitor on my XLR gaming mic.

amazing. update: wire snapped after a few months
edit after 6 months from purchase:as you can see in the picture attached that the wire has snapped at the point where the plastic protection ends. the earbud on that side doesn’t work anymore. i wouldn’t say i was handling it roughly, it’s just what happened after daily use on my laptop. i guess it makes sense as the wire itself is quite thin and only has a thin layer of rubber coating it. it’s a shame cause i loved these earbuds they sounded amazing and were quite comfy. the upside on this could be that the cable itself is replaceable and i could get a better quality one but most of them here cost just as much as the earbuds themselves. i don’t know, i’ll think about it, i might just get a new pair of entirely different ones for the price. i don’t like the fact that it seems quite impossible to find a contact email of the seller, i wanted to inquire them first if this sort of thing falls under the 12 month warranty.still worth buying i’d say, for the price most of these earbuds give out eventually, although i usually i definitely get a year’s worth of use out of them. the white noise issue i mentioned in my old review also disappeared when i upgraded my laptop so the kb’s were almost perfect.i left my old review down bellow if anyone wanted to read it still.Old review:i love them even though my laptop doesn’t do them justice. they sound beautiful for the price and the curved wire is surprisingly comfy to wear. i am not an audiophile so i can’t say much about the technicalities of the audio but they make it sound deep and layered instead of just flat out. really good. compared to the standard apple earbuds i’d say they’re quite similar, just these have the noise cancellation aspect and i’d say that the kb ears make everything sound a bit more realistic if that makes sense?anyway, definitely worth the money, just watch what you plug them into. my cheap laptop has some issues with the port location and how it relays sound, and because of it every time i plug the earphones in i get the 10 seconds of a very faint white noise. after some googling i found out that it’s apparently just my laptop’s fault. i also wouldn’t use the kb’s with the apple 3.5mm to lightning adapter and invest into a more expensive one if you want to listen with them on an iphone.overall, great purchase, definitely recommend!

If you don't buy these, you don't know what a deal you are missing.
I am not quite an audiophile - but certainly an audio snob always looking for the best of the best (of the best SIR!) and I am also an early adopter .... so needless to say I have more sets of earpods/headphones than blades of grass.Most of the ones I buy end up getting set aside and I go back to my old trusty pair of Shure 846's. The problem with my goregeous and lush 846's is that they isolate sound TOO well... so when gaming or talking or eating or anything other than JUST listening ... its too damned quiet.So when I started streaming, I looked for a good pair of IEM's that would allow me to play games, listen to music, and chat with people without irritating me. Looked on Amazon and found these cheap little things... no WAY it can do what I need it to do.Three weeks later, these little $20 KS1's are freaking awesome and I use them daily. No they aren't studio IEM quality - yes they do almost no mixing between left & right for directional audio - yes they feel a little cheap... BUT, the sound is very good, isolation is good, fit is really awesome (feels like nothing during even long sessions) and is compatible with anything I plug them into.For $20, you should RUN to get a pair of these because they are that good for the price.

Geweldig instapmodel
Deze iem heeft een leuk klankbeeld en zit heel gemakkelijk. Voor die prijs kan je hem echt niet laten liggen.

Buon prodotto.
Acquistati nel periodo del Prime Day a 16,50€.Ho preso queste in-ear monitor perché voglio sostituire le mie cuffie da DJ durante le prove con la Band (dopo 2-3 ore di lavoro le cuffie da DJ iniziano a fare male alle orecchie per la troppa pressione).Ma torniamo a questo prodotto. Come qualità prezzo va bene. Isolamento del rumore discreto. Suono quasi corposo. Ottime per provare con la Band e farvi anche qualche live di fascia medio/bassa. Non ho mai avuto problemi di audio e difetti.Spero di esservi stato d'aiuto.

Better of buying the KZ ZSN
Not that balanced, not the best quality cable.

Not just good "for the price" - these are just plain good!
After seeing a recommendation for these from a Youtuber, I figured they were worth a try. After all, what else can you get for this price? Once I got them, they were really good. I tried the different silicone tips they came with, the larger ones sealed blocked out all sound and really bumped up the bass...a bit much for my liking, so I went back to the mid sized ones that came installed on them and have really come to prefer them. After about a week, I stepped up to adding a very affordable Fiio DAC and could hear a distinct difference...for the better.I've moved on to trying headphones with that DAC, including ones that cost multiple times more than these IEMs, and these KBEAR KS1s are immeasurably better. More bass, but also much cleaner, clearer mids and highs.Don't let the low price deter you. These aren't "good for the price", they are flat out good regarless!
