Yinyoo KBEAR KS1 Wired Earphone Super bass Boost, in Ear Earbud, Stereo HiFi Headphones, Great Resolution Passive Noise Isolation, Dual Magnectic Circuit DD Detachable Cable(White Without mic)

At really low volume levels on my Redmi6 pro there's a hissing sound not that eminent if your not looking for it but it's annoying when u do. Though It works well in other phones. I can't say much about the sound quality and it's my first pair of iem. Thing is like 300 rs cheaper in concept kart's website but I've never ordered anything from there.

If you are a basshead these will be the perfect choice, even better than sony xb55 because, even though these are bass heavy, you can hear the details very good. I would say Blon bl03 is still better but they have different sound signature and there are things which these do better than BLON bl03.And the seller added the pouch to carry these earphones as a gift. I loved that!

I got this product seeing the video of dankpods and i was not disappointed. The sound quality is amazing and is just what i wanted

I did lot of research about this kbear ks1.. If you compared with Kz zsn pro x and kbear ks2 it is better choice... Overall listening kbear ks1 sound better than kz zsn pro x....Thank you concept kart for free carrying case

Good sound quality at this price!

I spent quite a few English pounds £ on headphones (  , BEATS, SONY, Bang & Olufsen, etc) which leads me to post this review : this has to be the best £20 I’ve ever spent on a pair of headphones (completely amazing) you will not regret this purchase if you are looking to plug them into a 3.5mm port (amazing sound) I personally purchased a headphone amp which cost me an extra £21 which turned turned these into my ultimate mobile music purchase (studio in my ears on the go)Do I recommend these (YES)Down Falls = None at the momentWill update if I find any faults (but I highly doubt it)

*** Review updated ***This was originally a 1-star review based on my experience with the product. I'm still not happy with the product, but the company have reached out to me, offered me a replacement (from other products in the range) or a refund where I don't have to return the product. I chose the latter, and they refunded same day.Based on the good customer service - refunding and saving me the trouble of going to the post office - I'm upgrading from 1 to 3-stars but leaving my initial comments below. There are a lot of positive reviews here, so it could be that I was unlucky with the particular unit I received - it's probably worth the risk given the refund policy.--- Original review as posted initially ---I'm getting a constant quiet hissing noise in the background when using these IEMs. The same environment with my (similarly priced) Sony MDR-ZX110AP's is completely silent.It's a pity, because the hardware design seems pretty nice.Apart from the hiss, my only other complaint is the cable length, I'd prefer if there was another 6-12" of cable run.

Update! Just bought the 'KZ ZSN Pro X Dual Driver In Ear' and can report that they are far superior to the KBEAR OS1PRO... Cheaper too. I have noticed that the reviews for KBEAR models are all clumped together too. For me (and whether I had a bad one) the expensive KBEAR OS1PRO is awful. The KBEAR KS1 (i have 2 of (1 x black and 1 x white) are awesome. The reason I tried the more expensive KBEAR OS1PRO was because I like these so much and felt that any upgrade would be worth the extra cash. It wasn't. Returned.I am not sure what everyone is raving about who left a 5 star review. Are they better than cheapo/old earbuds for sound quality? Not all! Are they as good as my Apple earbuds that came with my iPhone 12? No! They really sit well on the ear if you are busy but they could have done with a wire clip so as to pin it to the lapelle. Deep bass? It’s okay. I am not wowed like the people who have written the top reviews. I am just like ‘meh’. I’m keeping them though as they are better than my old Samasung ones and are great for noise cancellation. A tad overpriced I’d say too. If I alter my opinion I will update in the future.

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!

They sound great. They sound really good. Lets be clear they are definitely a budget product and you can tell from the feel, but they sound much more expensive than they are.
