Version equivocada

Compre la version que se ve en la foto y me enviaron el modelo viejo. Es algo imposible de prevenir, asi que la compra es muy arriesgada.
Los costos de envio son muy altos para mi pais ademas de la demora en aduana hacen que si hay un reclamo el producto deba enviarse nuevamente y recibirlo con costo.
Compre otros productos anteriormente sin problema pero esta vez todo lo que compre vino defectuoso.

Not same as shown in the picture

Not the same as shown in the picture. I mean where is the pairing button? The lid is somewhat not good enough and ear tips are pretty basic. The sound was quite good as per budget. The micro USB charging port by the way is a bummer for me. The product's packaging and delivery were good.

I got the earbuds in the mail a few months ago and it seemed to be low on battery at first. I charged it for two days and realized the left earbud wasn't charging. Linsoul sent me another pair and it works just fine now. The only other issue I have with the earbuds is that they don't stay in your ears that well. When working out at the gym, the right earbud tends to fall out here and there and the left feels like it can fall out any moment. I have to keep pushing it back in. I really like the earbuds other than that, great sound for such a low price!

Great earbuds, awful eartips

Wanted the S1s, but they were out of stock at the time I ordered, so I committed to buying the S1Ds instead.

Out of the box, they're nice little units. The case is okay, the texture is not very grippy and it feels like I'm holding a small bar of soap as it almost feels like it wants to slip out of my hand when I'm handling it. The earbuds themselves are also okay, but the smooth plastic also doesn't feel very nice to hold either when handling them out of the case, and I've almost dropped them a couple times while handling them. They're nice and light, however, and don't feel like they're weighing down my ears while I'm wearing them.

For usability, the touch controls are okay enough. They're not very sensitive, but I'm alright with them being that way because it doesn't just automatically make my phone react to every touch. I do have to tap them somewhat firmly to get them to react while in my ears, but it's totally alright to me.

The stock tips they come with aren't great either. They're thin and flimsy, and none of the three included sizes made a good seal in my ear no matter how I positioned them. The sound quality with the stock eartips was thin and weak with the lack of seal they had in my ears.

At the same time I bought the S1Ds, I ordered ZSN Pros as well, and tried the extra eartips that came with the ZSN Pros on the S1Ds. Those eartips changed the S1Ds. Past the all-plastic construction, the flimsy eartips, and the meh touch controls, their sonic qualities came to life with the better eartips. Highs and mids are full and colorful, and while not the clearest or detailed, they have a sparkle to them that brings music to life. The bass is rich and deep, and fills out the rest of the sound amazingly for such a compact setup. The perfect seal of the better eartips automatically made the S1Ds the best wireless earbuds I've listened to thus far, and made them my favorite earbuds to leave the house with.

If KZ can include better eartips with them, they would be amazing right out of the box. For $20 though, you'd have money leftover for replacement silicone tips, so I still feel these are a great value.

Good for price

Good sound quality, but don’t stay in ears quite as well as I would like (I typically use them for running). But all in all, a solid purchase

Great sound with sub par build quality.

The KZ S1 sound excellent! They sound better and are more comfortable than any other wireless buds I have ever tried. They were so comfortable in fact, I would forget that i was wearing them. However, after maybe one week of use the case will no longer charge the buds or tell them to turn off. On top of that the left earbud will have terrible interference and becomes completely unusable. It sounds like an old modem when AOL was connecting to the internet. I wish I could use them because were fantastic when they worked.

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”
    • 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.
