Hi There Head-Fi'ers

What we have here is the Sports version of an already awesome pair of IEMs. The KZ ATE S

I ordered this one after having some fitting issues with the KZ ATE. It took a month to arrive and the waiting was worthwhile.
This time, Knowledge Zenith gave this IEM a small cardboard box with the three pairs of tips and one pair is the special foam tip that takes comfort while listening to the next level, never did I put them off out of discomfort even after hours of listening. And now you can move and even sleep while wearing them!
 
What mainly differs these from the KZ ATE is the added Memory Wire, the function of this is to make sure that you never have to worry about these falling off from your ears. You have to adjust these according to the shape of your ear while you are wearing it OVER you ear, then this will act as a hook, but it is kinda bothersome at the beginning to make these adjustments until you get used to them and thank them for making your life easier.

The protection also increased,  as the Memory Wire keeps the wire safe at the junction of the wire and the cans, also some strain reliefs at the Y-splitter. The L-Shaped Jack with gold-plated jack stays with them.

The sound is actually nearly identical to those of KZ ATE's. The only difference I found was of the power output. The 'S' Version gives out more power and makes no hiss at high volumes. Bass is compact and hard and you could actually visualize sound with the bass. The Mid-Range is accurate and has little distortion.Treble is still the main treasure of these IEMs and they don't break off unless the record has problems in it, in this price range, I have not yet met it's match.

The wires are still sticky and Tangly, the body of the earphones are the same as the ATE. The Soundstage remains to be their main drawback.

Words can't express the goodness this brings and at this price, it is one of those earphones that you would feel good to keep and listen to minus the burden of expense. I'm quite hooked up with these IEMs and I am a bit biased with them.

Hope this was helpful for you!

I got my KZ-ATE from Amazon.com three weeks after I ordered it. I was just looking for budget earphones and from what I had heard from the hype about these IEMs, I decided to go for them since it was cheaper than most other and promised a higher Bang-For-Buck than the most I had observed, and boy oh Boy didn't they shine upon me! The waiting was totally worth it.
 
The IEMs came in a small stylish shield-shaped container, in which were three selections for the ear tips, one medium and one large size tip, and one foam tip. I had ordered the Transparent Bodied ones (including mic). They looked cool to wear and the wires were also clear from the outside. These looked amazing, the body was unusually box-shaped and the nozzle was freakishly long. Cables are not separable unfortunately but has good strain relief on the jack. The Y-splitter could be improved but it was okay for this price.
 

After I got home and connect these with my MP3 (Transcend MP350), I could not stop laughing at myself for doubting the performance of these easy-go-drivers. The single Dynamic-driver ATE left me speechless afterwards, hours passed by after putting thse on my ears yet I felt no fatigue and the music it delivered was just too good to be true in such a price.
 
The Bass was quite pronounced and controlled and clean, not messy like some I've heard from. The Mid-Range was WAY TOO GOOD! The details it rendered made me hear new details in the same music I've listened for years. This made me realize that I was knocking on the gates of a new world of audio heaven that I have not known before, and thus my journey of Hi-Fi started. Anyways, the Treble was confusing at first then I had to learn what was I listening to, after I got a hold of what was the High-range, I found that KZ-ATE was quite clear and did not hiss in the ears even at high volumes. The Soundstage was just enough to cover your head, but this has an unusual extension from the left side. The separation was adequate, you can sense where the sound had originated from.

The wire was sticky in the humid environment I dwell in, and was kinda tangly, but I grew up fighting this so it was not so much of an issue to me. The only great flaw of these are that they are quite annoying when you tilt your head and they just fall from your ears, even though I'm using the foam tip, I have a medium sized Auditory Canal lumen. You can't sleep wearing these, or run or look up or just any movement involving your head.
 
I am quite new to the world of Audio and I am just too obsessed over these, but I am quite sure that these will be worth collecting and using, they are just too much fun!
