KZ Acoustics started as a brand by enthusiasts for enthusiasts and has 10 years of experience in the development and production of HiFi In-Ear Monitors. Our products have been featured, reviewed and recommended in popular websites and have been recognized by experts in the audio field. While other products on the market may achieve one or two of these aspects, accomplishing all three has rarely been seen - until now. Our team wanted to design a set of in ear monitors that you will never want to take out - simply because you won’t even notice that they’re there. The resin housing of the S2 has been moulded to perfectly match the shape of your ear, and our wide selection of high quality ear tips ensures everyone will have a perfect seal.
In terms of software, we opted for simplicity. It should be easy and painless to use your TWS earbuds. Pairing can be done with 3 simple steps, and once connected, the S2 will automatically reconnect to your device whenever you pick it up. And with our intuitive controls, you won’t have to think twice about whether to play the next track or answer the call. Please don't use any faster charger or faster-charging port on a power bank, power higher 5A will damage the embedded components.

Check out my full video review on these here: https://youtu.be/KdgCf4WK2VE
Connection is fiddly, falls of easily out my ears regardless of tip size. Sound is fine and really good for the price, just wish that it stuck around better.
I would of gave 5 stars, but I did not receive the upgraded ear tips I ordered. The headsets are still awesome, sounds fantastic. Great purchase.
I used these once and they sounded fine. A few months later I tried but batteries will not charge. Wasted money.
Had these for half a year, bought them off indiegogo as soon as they were available for pre-order.
However a few days ago the right earbuds doesn't charge itself back anymore. I have to reseat them in the charging box every few hours so the battery doesn't get depleted.
Should've made them out of better materials, using better quality control - I, at least, would've paid 10 bucks more for them.
Purchased these through the Indiegogo offering, and so far both have worked. One quality control issue: The screen and small black sponge behind it in the left ear stem is not glued in. I have attempted to glue it back in using superglue.
Connectivity: In standard Bluetooth mode, channel drop is very apparent, happens about every 7 to 10 minutes when walking around. Changing my phone to the APTX blue tooth mode eliminates this.
Sound: Sound is good, even with the supplied tips. There is a "high definition" mode, which seems to be a bass boost.
Battery life: no complaints. At least three hours on a charge, haven't worn them longer than that.
Comfort: These are pretty comfortable, and fit pretty tightly in my ear canals.
Will watch for some of the other issues people have reported RE quality and failure.
After 3 months of usage the left unit now turns off instantly after pairing
Got 3 pairs of this earbuds, a pair in black and another.
One of them (right) can no longer be charged.
The black right earbud is no longer responsive.
The defective unit has been returned!
The replacement unit does not arrive!
Horrible customer service on KZ's end as
I emailed many times, but no reply!
Just got KZ-S2 black 2 weeks back. I am very satisfied with the sound quality especially the bass. No issue connecting to my Xiaomi Mi Mix 3. However i found that my casing is slightly different. Without the power check button & chrome stripe at the rear. Also at the cover of the case, its stated 400mA and not 500mA.
How come the 2 versions??? I felt i had been mislead.... other than this, i am very happy with earbuds.
I just picked these up from indiegogo. This is my first pair of TWS IEMs so I don't have other TWS's to compare them to. I am overall happy with the sound quality for the price. The sound is definitely on the brighter side, but they still produce lows but not punchy lows. I do experience connectivity issues where the connection wants to cut out, but it only happens when the phone they are connected to is about a foot away or closer from the earbuds, in very close proximity. It's a great starter set if you can get them at a good price. I ordered them with the foam ear tips but the tips never arrived.
