KZ S1 / S1D

Excellent TWS for bang for the buck

The S1 is really good! It's my 2nd pair of TWS and the quality is really good. The only thing I would change is the ear tip, these ones don't fit me perfectly but people's mileage may vary. I also should have gotten the S1Ds since I prefer a stronger bass. But hey, no complaints here since the price is really good.

Did Not Arrive

Can’t tell my feedback, sadly, because it did not arrive yet. I wonder if it will...

Headphones error

Superb sounds quality.
Unfortunately the left side stop working and charging after a week of using.
Can you provide me solution?
I ordered it from official KZ store in AliExpress.

Great sound, iffy connectivity

I get cutouts regularly with these. Not sure if mine is a dud, but it's annoying. Sound wise, it's great, case size is small and IEM is comfortable. Price is right.

Incredible Value

These are now my go-to TWS IEMs. Very good sound. Still has a bit of the KZ treble (1 DD 1BA version) but for the details and sound stage it's the best I've heard from a TWS. Fit is easy and it doesn't stick out much like others.

Battery life is ok. I use these half to one hour at a time so I have not run in to low battery problems but it has around 3 hours maybe more.

These are the loudest TWS iems I have tried and rarely use them past 80% even in loud public places.

Build quality is ok for $25. The charging red status light on the IEMs is way to dim.

Hope to see the following improvements in the next version:
Brighter charging led.
Slightly lower treble spike and improved bass. Keep the treble extention and sound stage.
Better material/shell construction.

If they can do this it would be worth the extra money but for now these will do.

Soundwise, beats the Airpods

Picked these up for on-the-go moments.
Soundwise, it for sure beats the airpods. Deep bass and great details.
Battery life...what in the world.
I've been using them for 2 weeks, with about 1 hour use per day. And I have not had to plug them in to charge. I don't understand how the battery lasts this long. wow.
The software is decent.
Pairing is easy and all of the functions work seamlessly.
Only complaint is the compatibility with the case. Sometimes, taking it out of the case doesn't turn on the earbuds, so I have to manually touch the earbuds for 3 seconds to turn them on.
But it's $25. For $25, you can beat the AirPods.

Outstanding Performance

These have great bass response. I was shocked that the Bluetooth works so clearly as well!
