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.

KZ S1D

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.
