The IEM is good but there r not giving the same cable that was shown above.

jozef krasula

Great sound, incredible IEM for this price, nice buy, thank you linsoul...

David Gross
all hiss all the time

clear crisp and loud. not usable because of hiss that can be heard over all music. tried four different sources and the same hiss with all of them :-(

Dylan Moore
Awesome IEM

Of all the budget IEMs I've tried, this is by far my favorite. The soundstage is really wide and can really get great detail of all the instruments. It takes quite a bit of eq to get it to my preference, but I highly recommend it!

Testé et approuvé par l'homme qui entend une plume tomber !

Je ne vais pas vous faire un long cours sur des notions techniques et des capacité physiologiques variables selon les individus.
Alors la seule chose que je vais dire est : Si vous hésitez à acheter ce produit n'hésitez plus, foncez !
(attention, à mon sens il est important d'avoir un équaliseur sur votre système de diffusion du son, réglage en forme de tête de flèche)

J'ai acheté plusieurs références de casques Linsoul et celui-ci est de loin mon préféré.
Ma femme et ma fille sont devenues des clientes définitives des casques Linsoul en une seule écoute, depuis elles en ont acheté pour tous leurs appareils (PC, MP3, Smartphone)

Je n'ai rien d'autre à dire pour vous convaincre que de faire appel à votre curiosité et votre logique : Depuis que j'ai acquis ce Linsoul KZ-ZAX j'ai laissé mon coûteux sennheiser au placard de façon définitive.


for the price, very good sound, which takes the equalizer very well

Great in ear headphones

Sound quality is amazing the only thing I would say is the highs can be a little sharp but it won't be a problem if you use at a lower volume

Best among KZ ZSN ProX, ZAS, ZSX

I bought all 4 models above and I was shocked the ZAX was my favourite in overall:
The long angled tip coupled with the light slim body makes the fit and wear seamless and stays put with a good seal without any efforts.
Sound quality: That bass, that control of sound and comfort over long listening times is undisputed. The ZSX was close but the bass is subdued. The ZAS was falling far behind No Bass, No Loud...perhaps it still needs some burning in and getting used. Or perhaps all my 4 iems need burning in!. BUT the ZAX was good from out of the box: Loud, Full balanced bass, good mids and harshness. Well, as with all IEMs after several hours your ears start to pain and you might get a headache because when the sound is that sweet, you can't help but keep the volume up.
Do yourself a favor and getter better tips and an upgrade cable: I had a selection of silicon/rubber tips as well as memory foam tips to choose from; each tip sounds way different untill you get the right one. ALSO, get either a tripowin zonie cable, or a able from KZ ZAS to use with this iem.

Linsoul is speedy in their order processing and shipping. The free shipping program for orders above $239 enticed me to come for a second batch of buy (more KZ ZAX!)

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.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*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 270USD, 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”

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.
