Bluetooth 5.0 also allows connectivity distances of close to 1000ft (that’s 4x the range of previous generation!) and incredibly fast ISM band range. The combination of Bluetooth 5.0 and the special gaming mode - High Performance mode, offers a faster transmission speed of the sound signal. From now on, you can enjoy an ultra-low latency gaming experience with your best gaming partner KZ S2

Compared to other leading Bluetooth products on the market, our integration of the 8763 chip into the S2 results in significantly more stable sync even at further distances

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.

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.

Sound is good especially the bass

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.

Shipping FAQ

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 269USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

What happens if the parcel has been shipped but not delivered?
  1. First, kindly contact your local courier using the local tracking number.
    If your parcel were to be in transit for at least 3 months, it may have been lost in transit.
    For orders below $50USD, you may either opt for a one-time reshipment of parcel OR a full refund of the amount paid in cash via PayPal/Credit/Debit card.
    For orders above $50USD, we will only process a 50% refund of your order paid in cash via PayPal/Credit/Debit card. Should there be any concern about Standard Shipping, you are encouraged to opt for DHL Express Shipping instead.
  2. Customers are to bear the consequences and fees incurred, if the parcel was undelivered due to any of the following situation:
    • Wrong address or phone number provided by recipient
    • Recipient was uncontactable when courier company contacted
    • Refusal to sign for the package by recipient
    • Lost or damaged parcel because recipient opted for “no-signature delivery”
    • Refusal to pay for the local tax/processing fee by recipient
    • Refusal to provide supporting documents for custom clearance by recipient
Who will pay for the import tax/custom fees

Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.

Should you be unwilling to pay for the fees and reject the delivery of the parcel, you will still have to pay for the shipping cost. Linsoul will only refund the amount of your order after deducting the two-way shipping fees incurred.
