Helloo, im back , HELP, KZ ZSR is weird!

It seem it is out of phase? or something, its not centered anymore, sound comes quieter/different from the left side?

what may be the problem? KZ quality controll? by the way Gearbest refunded me 3,80€ for 15,50€ that i pad for ZSR...oh well.(they offered for 10€ ship another one,but i don wanna another crappy quality zsr....)

Whats next ZS10 perhaps? Please advice? (take apart and fix something?)

Thank you!

Try turning ONE of the cables the opposite way, and retest the phase tests on audiocheck.net.

Maybe we didn't pay proper attention to these strange ZSE things. After the re-wiring I'm listening to them again and comparing to my Swing IE800 and ZS3 (shiny one with Slater mod and news cables), my two previous bassy and outdoors IEMs. The thing is, I think the ZSE sounds a little bit better... but I'm still listening and trying different things. I suspect the price, design and maybe bad QC made many of us forget about them.
Using New Bee tips, Fiio X1 and Xduoo X3 in Rockbox mode, and yes, they seem to need more juice than the other cheaper KZ models, the drivers are probably wired in parallel.



About the re-wiring in the Out of Phase models (remember only to re-wire one side, no matter which one):
1. use a thin knife or cutter along the middle of the plastic capsule with care. Little by little it's going to split the two halves, but there is a little notch near the nozzle holding it together that it's most probably going to crack before everything comes out. (You can see where the notch is in the picture, in the L side one below, the hole in the clear plastic where both halves meet).
2. the black rubber piece holding the cable and the cable itself comes out easily so you can separate them from the two-driver half and identify the two little colored cables.
3. Use the solderer to free the little cables and re-solder them in the reverse order.
4. Get back the cable, rubber piece and tuck everything in as before. Apply some glue to the plastic halves. The notch that was holding it together is probably broken, and the general pressure is gone, but with some glue it appears to hold fine.

Auvio's work well with 90% of my iem's and Starlines pretty much cover the rest, my latest acquisition and I must say their players do sound sweet but as many have said the filing storage attributes leave something to be desired! Who knew as a 61 year old man I'd like the boy band Super Jr:astonished: Good thing since I now have all their signatures on my player, still not quite as cool as my 30GB Classic U2 Pod:rolling_eyes:


Hey, I have the U2 iPod too!

Did a 128GB SSD upgrade. Debating whether to do the capacitor mod...I don't use it much though, as my latest car has USB port that can play flac files on a super mini USB drive & Apple CarPlay (and for DAP use I use my Rockbox xduoo X3).

I missed out on buying a backup pair of ZS5(i) but several weeks ago I traded a very popular and very good IEM to secure a backup ZS5(i). I now own two pair of the ZS5(i).
Lucky You! At beginning of my IT01 "burn-in" I even though about changing deal for ZS5v1 <> IT01 :D
But not anymore.
I still wish another ZS5v1 but noone selling in EU or willing to send it to EU ;(

PS! Please change showcase item pics back to normal. They are somewhat misguiding :wink:

They are quite tip dependant as well. I can't remember if you're using wide bore Whirlwinds or Auvio tips. But obviously tip rolling might change your mind (which you may already have done).

Or it could just be they just don't sound good to your ears. Nothing wrong with that. But there sure are heaps of people that love the CM5, so if you want to sell them I'm sure you'll have no issues whatsoever.

Yeah I find the wide bores actually make them sound worse, the best sound I've gotten out of them so far is by using Sony hybrids. I've ordered 30 pairs of KZ Starlines, but it will take a while for them to be delivered

The CM5 have a weird peak up in the higher frequencies for me, I don't know what it is.

Will see what happens after like 50 hours of burn in, if they don't change/improve I'll probably sell them on.

That's just mind boggling :)

What's even crazier is that we were only at like pg.1,300 in November when all the 11/11 sales were going on. This has to be one of the most active threads on the site.

I wish this could be a sticky post/notification somewhere, somehow.

The Cynical me, (apparently the only me) tends to think even if it was a side bar on every page, the unmentionable would still come up at least weekly:scream:

That is correct, while as of now aptX is pretty common in chi-fi equipment, true AAC support is quite rare. So far only 2 products that I know of are Fiio BTR1 v2 and the newly launched Mi bluetooth neckband (unconfirmed)
Hmm. No. Most of Sony Bluetooth headphones and their car stereos support AAC over BT
One more misunderstanding I find people have is that Apple is the license holder of AAC. It is actually the same licensing body that invented MP3.

I second that Lucky You and it was an amicable trade:beerchug: Still have my gray 5v1 and will be holding onto this pair, backups are important as I just re-ordered a new Gray Benjie S5 and ZS6's in red since I gave my old ones to a close friend back in Texas a few weeks back.

Glad these Blue Babies have a new (and loving) home:)

Goodness gracious.... I started with a KZ ZS3 for my running headphones, then bought a ZS6 to see how it stacked up to my Ultimate ears triple fi 10 (smoked them in terms of clarity/treble after modding the headphones with the gauze over the BA drivers), and now I have a pair of EDR1s and some ZS10's (one is being gifted for my brother) with the TRN bluetooth APT-X bluetooth cable on the way.

Darn it. gotta stop reading this thread. What's ironic is that the TRN bluetooth cable is sold with other brands like AUKEY however it doesn't have the necessary 2 pin cable connector so in reality we're paying a premium for the 2 pin KZ variant.

and so the waiting game continues.

side note: how do you add a signature to your posts? I can't seem to find it in the option settings.

Hover your mouse over your name at the very top right side of the screen, and a little menu will pop up. Signature is the 2nd thing down on the left hand side of the list.
