Really? Then I do NOT want that discount cuz I`ve suspected from day 1 audiobudget site released, that this guy is subjective, paid to promo and lean reviews according to "discount".

Meh, how much money is there in "pushing" 8$ iems? lol
I tried a few of his reviewed items and he was more or less accurate on the Bass and Highs side of things, when it comes to Mids his hearing is 100% immune to harsh\distorting mids.

I guess we need to remember that hearing itself is subjective and dependent of various factors like Earwax and hearing loss.

Answer - very much! The more product gets positive reviews and promo the more customers and low-budget IEM has VERY large consumer base.
And I agree - there are very many various factors in reviewing products... but subjectiveness should not be one of them and if added possible "paid review/promo" factor - it is very untrustful review site that may leave many ppl disappointed.
And as we have seen in head-fi threads and from respected reviewers, it seems to be unfortunately so.
No need to defend such sites and spread it. That guy was banned from here - for a reason.
And personally, after seeing such "discount code", makes me think about some certain AE sellers promoting their shops through that site.

Now lets stop this discussion here and return to KZ.

Btw, I decided to cancel my ZS5 order from NiceHCK and get it somewhere else for little cheaper (without discount codes).

That` s where I ordered mine. I hope it isn`t "second Q batch" due to being cheaper.

So what is the comfort going to be like on these ZS5? Looking at those angular edges makes me... uncomfortable. Any comfort impressions?

Also, would anyone recommend the silver cable over the regular ones? I'm skeptical it will affect audio quality, but what about microphonics, comfort, durability. Is it worth getting the silver for a couple dollars more? Looks like they don't have the formed ear hook...

Hey, to those with the ZS3. I found a new mod tonight.

It has been previously posted by a few people that removing the red screen on the very end of the nozzle affects the sound. Removing it reduces the bass quantity slightly (while simultaneously removing the muddiness), and also improves the midrange.

Well, I found a different mod that makes further improvements.

BEHIND the red screen is a small piece of black acoustic foam. It's stuffed in the very tip of the plastic tube (the color of the plastic tube might be red or blue). It's exactly like the piece of foam stuffed inside of the shiny gold ED9 filter. Anyways, you REMOVE this piece of foam by just grabbing it with the tip of a sewing needle. You'll need a flashlight to assist seeing down inside of the nozzle to where the foam is. Carefully set aside the foam - they're extremely small and easy to lose. You can store the foam pieces in a small ziplock baggie like the one that many silicone eartips come in.

The change is a very noticeable improvement - the boominess that the ZS3 had is now gone, upper mids are less recessed, and the treble is sparkly and clear. They kind of remind me of an improved ATR, but I need to A/B them with the ATR to verify. Synthesizers, pianos, & guitars sound great.

It's tuned much more towards neutral with the mods, but there's still plenty of bass when called upon. It just isn't boomy and muddy like it was stock. Don't get me wrong, I think the ZS3 is a pretty good in-ear (especially for bassheads). I just know a lot of people are turned off by its overpowering bass that dominates the whole listening experience. This mod corrects that.

It's up to you if you remove the foam yet put the red screen back, or remove both the foam and the red screen. It's easy enough to try it both ways and see which you like better. I settled on removing both after trying it both ways. Just keep an eye on ear wax buildup inside the nozzle if you run with no red screen (remove ear tip every once in a while and carefully clean out any funk).

The mod is very easy, takes less than 30 seconds total, and is totally reversible.

You use the sewing needle (or small straightened paper clip) for removing both the red screen and the black foam. Gently pry the edge of the red screen using the needle and it will pop right up. It's just held on by a ring of sticky adhesive around the edge. I stuck mine to a piece of wax paper to save for future keeping, as it sticks right back onto the end of the ZS3 nozzle if you ever need to put the red screen back (instead of wax paper, you could use anything non-stick - plastic wrap, sandwich baggie, or the slick paper backing from a peeled-off sticker or vinyl graphics.

Here's photos of the red screen so you know what to expect:



The following interior diagram will show you everything that you need to know (you don't actually open the shell for the foam mod - the interior diagram is just to illustrate where the foam is located):


UPDATE: I found a camera lens and settings that would allow me to get a good shot of the foam. It's impossible to gauge the depth in this photo, but that foam is located about 1/4" down inside the nozzle:


Here's what the piece of foam looks like after you've removed it with the needle (it gets more compressed once inside the plastic tube):



Also, while you're at it you may as well use the sewing needle to verify that the vent hole is open and not blocked. Just poke it with the sewing needle (or the tip of a thumbtack) and make sure it's not blocked with glue.

One more thing - even if you don't plan on removing the foam, I would strongly recommend that you at least peek under the red screens of your ZS3. Something that has always bothered me about 1 of my pairs of my ZS3 is that 1 side never sounded quite right. Well, low and behold I found that the foam on the 'never quite right' side was not even in the plastic tube, but just floating around freely inside the nozzle directly under the red screen. So at a minimum, looking under the red screens will allow you to make sure both of your foam pieces are inserted properly into the ends of the plastic nozzle. There have been reports of sound mismatches on 1 side. Early batches of the ZS3 had a crushed sound tube. Those were recalled a long time ago, so if you have a relatively recent ZS3 and you have something odd going on with 1 side, it could be that the foam isn't situated in the tube properly.

Let me know if you have any questions.

P.S. - To the advanced IEM builders/modders out there, as you can see from the exploded diagram this would be an excellent host for turning into a hybrid DD + BA. The shell is easy to open, it's comfortable as heck, and there's plenty of room inside for a crossover in the shell & a BA driver inside the nozzle tube. Looking at the above photo, it almost looks as if KZ was planning that all along, and it wouldn't surprise me if a "ZS4" comes out as a dual hybrid using this same shell as they already have the shell tooling. Also, it would be easy to swap out the plastic tube for a copper one, as the plastic is extremely thin (it looks exactly like a piece of heat shrink tubing that hasn't been heated/shrunk; or it could also be a piece of drinking straw). It's that thin & flimsy.

This is a fantastic write-up. Thank you very much!!

The few HF members that have weighed in so far have said that the sound quality is great but indicated that the comfort is not so great. Numerous comments about them sticking out of the ear, and at least 1 person said they can only wear them for a short period of time before having to remove them.

Unfortunately, I'm fearful that this will be the achilles heel of the ZS5.

There's always new stuff coming out; don't sweat it. Especially KZ, who release new earphones every month or more. DM8 is no slouch (especially bass, which the ZS5 is lacking according to reports).

Hmm vocals wise, what's better? ZS3, ATE, ZST, ED12 or ZS5? I listen to a lot of anime songs that are female vocal heavy.

Between ZS3, ATE, & ZST, I would have to say ZST for sure (for your stated genre).

I have never seen a single person that has ever said the ED12 was good, but I have seen a number of not-so-good comments about it on HF. It's just not that popular of a model for some reason, so not a lot of people own it. And the ZS5 is too new at the moment, so there's barely a handful of people on HF that have commented on it so far. The results about the ZS5's SOUND has been very positive though (and is certainly in-line with your target genre).

So my advice would be if you want a sure thing & you need it soon, go for the ZST. It's 1/3 of the cost of the ZS5 and is a very capable earphone. From personal experience, I can also say that the ZST is very comfortable, but most early reports I have read on HF regarding the ZS5 is that it is NOT comfortable to wear due to it's large size & sharp angled shell design.

However, if you are willing to wait a while for the flood of ZS5s to hit, you'll be able to get a lot of people's opinion before making your final decision. Exactly how long of a wait is anyone's guess at the moment, as most dealers are currently only taking pre-orders. So the wait will involve 1. the time it takes for the Chinese dealers to actually receive stock, and 2. more waiting for it to be shipped from China to wherever you are located.

Hope that helps.
