so i need amp to run this iem perfectly but i don't amp, i use with my smartphone and i just crank the volume seem to fix it. But why this iem hungry power?

 
Not too sure if I can help since I don't design the IEM. It depends on the materials and other design choices KZ have. I only just point out my observations. You should fine an improvement when you try this with an amp in the future or a DAP. If you are happy as it is that's no problem at all! Most of my casual listening friends who tried it with phones are happy enough it seems. I just find that the sound is a lot more defined and scales up when I use a DAP with hi-res lossless files.

That is quite interesting.  Thanks for the info.  Although looking back I'm not sure if it was a polarity issue, I'm pretty sure I put it on the correct way.  Cause when I put them on, I checked the positions, and I remember the first time I put it on wrong, so I had to double back and re-plug it.
 
I agree.  I bought from Penon Audio, and the Manager there said that they dropped every one of KZ's products because of QC (They were dropping AuGlamour too).  But they were still selling the KZ ZST.  They said that this one is still OK.  So maybe I'm lucky?  I don't know.

Huh, is KZ QC that bad?  I haven't seen too many failures in this thread.

Not so sure myself.  But it's what one of the members have stated.  I purchased 3 KZ ZST's.  I've only opened one.  Will let you know when I open the other two.

My track record is 2/11 and 1 cable with serious defects ( channel imablance ) and 2/11 with minor defects ( popping when inserted in ear, grille that's fallen off)
 
for a total of 4/11 having some sort of issue.

Holy.  That is really bad.  I didn't expect that, given so many people with good responses.  The reviews are all really good... I wonder how that happened for you.  Which models did you buy?

The ones with serious problems were the ED12 and ZS1.  Minor defects were ZST and ZS3.

7th anniversary sales of aliexpress are next week, they are already showing prices, but it's really not the big sales I saw last year and on 11.11.
Only the ZST colors price has dropped, others like ZS3 are still on the 18ish$ this time the sales are BS
I remember buying the ZS3 for 10$ on 11.11
I was hoping to get the new ZS3 cable + mic for under 5$ but no!

My colorful ZST is all fine (both cables) but my ZS3 stock cable housing is loose on the right side, loose enough that the wire falls out with relatively low effort tugging e.g. just taking it out of my ear.  Using the silver cable is fine, so likely the wire housing on the stock cable was slightly off. I managed to get a small refund (the cost of a pair of stock cables) from the seller for this.
 
Still, for this price level, you have to expect some corners to be cut.  Thankfully sound quality isn't one of them!

The ZS3 is $7.99 on gearbest though. Good enough?

haha, yeah

Hey, what do you think of your W1 Pros?

At ~$4 price, they just can't go wrong. Almost flat sound signature (warm tendency) with tight bass. Mids are decent, and highs are a bit recessed. Soundstage and clarity is okay. IMO the best features are the cable, it's detachable and have good coating (no tangle and microphonics at all). It's perfect for workouts, I think.

Sadly i find the price in local shop near me to be as cheap or sometimes even cheaper than the sale price. Sometimes I am glad that i live in Indonesia because jaknot always sell chinese stuff cheaper than those "sale" price.

Well, it should be noted that w1 pro is not using conventional mmcx cable, and the cheapest compatible cable that i can find in AE cost thrice of its price. While w1 pro is decent, just don't think of it as an iem with removable cable
