did not know how it compare with other dual driver headphone. If "dual driver" is a technology direction or just gimmick?

Dual-driver simply means that there are two driver units per side (usually connected in two-way configuration; each driver is used to cover a certain frequency band).
Other IEMs with dual-driver, two-way configuration are for example the Brainwavz R1, Brainwavz R3, Havi B3 Pro I, Shure SE425, Fidue A73, ...

Oh, I plan of some thing new like dual driver to try. Compare with ZS1, Brainwavz R1, VJJB v1s and the TTPOD T1 looks very nice. If have them, any characteristic or differentia of them. Is there any sound characteristic of dual driver? I get a little bit curious, yeah, prepare hybrid headphone too. How about xiaomi hybrid, looks nice

If dual-drivers are implemented properly, they can have a very positive effect on sound (resolution, control, ... as every driver is only responsible for a certain frequency range). On the other hand, that also brings a couple of problems, like possible phase mismatch or a somewhat failed transition between both drivers.

Great review man! Though, I think I like them a lot more than you do, haha. That failed transition between drivers is what makes them so special and enjoyable to my ears.

Hi mate, thanks.
I wouldn't say that I don't like them, but there are (imho) better KZ IEMs that aren't shy on the bass either. On their own, the ZS1 would be quite good, but the ZN1 is imho just better (although its bass is rather soft/spongy as well), with the better soundstage (why the heck did they cover the ZS1's tweeters' rear vents?!).
The transition between both drivers isn't that bad by the way, but the ZS1 doesn't feel as coherent as the ZN1, so I digged deeper (sine sweeps, FR measurements) and found out that there is a narrow dip at around 550 Hz which leads to the conclusion that the transition frequency of both drivers isn't 100% correct.
Though, I would say coherency is about 80% good and the ZS1 have got a much better transition between the woofer and tweeter than many cheap (i.e.) Logitech desktop speaker systems (have my first cousin once removed's Z333 here for repair purpose and it purely sucks; the ZS1 is at least two classes better).
For the money, the ZS1 do a good job (but there are, as I said, a few things that keep it away from an objectively better rating).

jvsaaaaa
Should i get this over the ed9?

@HiFiChris Can you please make ZN1 review? I can't find some nowhere.
Thinking to try KZ first time. Thinking between ATE & ZN1 (w/ or w/o amp)
If someone thinks that ED9/10/11 is a better choice I'm nothing but listening to the coming point.

Sorry, I fear I don't have the time for that at the moment, there are other reviews planned for the next time, so it would take some months.
ZN1 is definitely a bit better, more coherent, much larger soundstage, more treble and more balanced mids/highs (but bass-heavy as well).
The amp box is helpful for equalizing bass/treble, but it is quite heavy and battery discharges rather quickly when not in use.
You could also look at the HDS1 by the way, fairly balanced sound with exceptional resolution for the price; soundstage is a little small though.
