The Journey of KZ S2 TWS-Buy With Confidence

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. 

As simple as taking them out of their charging box.

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.

Didn't work

The pair I was sent didn't work - didn't charge, didn't connect via bluetooth (didn't live long enough to even try). Manufacturer eventually declared a fault with the headphones and was sent a replacement pair - exactly the same. Linsoul were helpful enough both times but still left a little out of pocket after a refund due to currency exchange cost nailing me both ways.

I don't particularly like leaving bad reviews but having received a grand total of no working headphones I can't exactly recommend them.

Dear customer,

We sincerely apologize for the inconvenience and frustration you experienced with our product. It is deeply disappointing to hear that not one but two pairs of headphones failed to meet your expectations, despite our efforts to provide replacements.

We acknowledge your feedback regarding the currency exchange costs incurred, and we regret any financial inconvenience this may have caused you. Please understand that while we strive to offer exceptional products and service, external factors such as exchange rates are beyond our control.

Upon receiving your initial feedback, we promptly sent you a replacement pair of headphones. However, we understand that the issue persisted, and we subsequently processed a refund for your purchase. We appreciate your patience and cooperation throughout this process.

Your feedback is invaluable to us, and we take it seriously. We are continuously working to improve our products and processes to ensure that such incidents are minimized in the future.

Once again, we apologize for the inconvenience you have experienced and thank you for bringing this matter to our attention. We value your patronage and hope for the opportunity to serve you better in the future.

Pretty disappointing steps backwards...

I got these headphones a little over a month ago. After owning a pair of S1D headphones, and finding them to be some of the best headphones i'd owned, I figured i'd go ahead and get the new version, the S2, while they were on sale. That...seems to have been a mistake.

The audio quality is good, but the build quality leaves a TON to be desired. The headphones don't seem to like to stay attached to the charging contacts in the headphone case, leaving me with situations where they are not charged when I go to use them. The headphone batteries themselves seem to be of poor quality, as they never show more than 60 percent charge on my phone, and just can't seem to go longer than 1 hour and 15 minute before proclaiming 'low battery'.

All in all, I've replaced them with a pair from another manufacturer, and won't be recommending this brand to anyone in the future.

Hello there,

We are sorry about your problem. Please feel assured that we will try our best to help you to fix the problem.

Regarding the issue of the headphones not charging properly, we have sent you an email to gather more details in order to assist you in resolving the problem.

Thank you for your time.

Waste of $

They worked for about 1 month then the sound quality decompensated rapidly over the next few weeks to complete failure.

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.

Love these headsets

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.

Sounded good

I used these once and they sounded fine. A few months later I tried but batteries will not charge. Wasted money.

Good IEMs, Poor Quality Control

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.

Good IEMS, Bluetooth connectivity issues

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.
