This one took forever, but I think I really nailed the essence of both pairs:

Happy Saturday fellas!

I found this $3 off code for some KZ models, ED9, ED9 with mic, black ATE with mic, ED SE with mic and silver ED1 with mic.
It is only valid on the official store on Amazon.
Code: headfier
 
Cheerio!

Interior IEM pics the **** K3003s purchased from AliExpress seller Anna Outdoor Club.
These were defective right out the box, and aint gonna get my money back, so spent some time dissembling instead of smashing them with a hammer!
At least looks like what they claim to be selling; but the QC is pretty poor.
Notice the masking tape used to shield the wires from the metal case.  The assembly glue was also a mess and blocking one of the vent holes, but doubt that is the reason for the distorted sound. (I cleaned up / removed much of the snot before taking these pics)
Also don't think the housing is made of stainless steel as they claim, as it is ferrous.


Okay, time to move on...

How did you manage to pull them apart without damaging the shells? I'm planning to mod an IEM(metal shell) but don't know how to open the shell without damaging the shells. It would b of great help if you could share your exp.
thanks

The internals don't look that bad now it's open. You could replace the dynamic driver with a new one, that's what I would do, those balanced armature's will be fine still.

Maybe these fit:

And I found some shells as well that would work well if you damage the originals, or make some real DIY:

These look like better drivers

Also looking at the pics people have posted on alixpress, Anna outdoor club is supplying the newer version of this now, and I think you got unlucky with that pair.
I have also contacted her before purchasing the order, and asked her to please test the iem's, before sending them.
Also the latest feedbacks are looking good to. However time will reveal what sort of surprise I'm in for.

Not just a badly soldered ground wire somewhere?

Not just a badly soldered ground wire somewhere?

The distorting driver is (usually) caused by a break down in the coil in the dynamic driver, (this had happened to a few drivers during burning in) and the fact it got worse over time as well leads to this fault as well.

Thanks for the info.
The dynamic drivers on this particular K3 version measures only 8mm diameter.
The housing that the driver is pressed into is 8.17mm, so dont think a 10mm driver will work.
But your suggestions got me thinking and I may try to find replacement drivers and throw in some mods as well.
 
Am 99.9% sure the problem is not from a bad solder joint; but it could be from a small short in one of the connections.
When I got them, only the left side sound was distorted.  With more burn in time, the right side developed the same problem; and finally sounded like the dynamic drivers broke.
Interesting is that after taking apart that one side, I can hear sound from the dynamic driver.
The iron BAs seem to be working fine.

Yeah BA's are really tough and hard to kill, also they generally just blow out and stop from my experiences with wrecking them.

These drivers are very popular, probably sound great, are 8mm and cheap:

I tried with my cell phone, the paypal payment didn't go through and there was no screen after the payment details confirming the purchase.
So I tried with my desktop and the same thing happened.

-Buying rhe Lz A2, to give that post some context!

I tested it earlier by going till the last step after signing into paypal before paying the confirm button. Did u try a different browser? do u have ad block on?
 
edit: seller says it should be working they just tested it

 

[RedJohn456]

Just listened to an entire children of bodom album through the LZ A2, running out of my Geek Out V2. Haven't done that in awhile. loving how it sounds with the JVC soft wide bore tips. Also ordered these tips

Lets see how they sound with the A2. I like how I get no fatigue even though I used the A2 for 4 hours today. Uncanny how much it reminds me of the sony XBA Z5!

In the last picture the spout of the BA seems broken. Can you tell me if there's a number on the BA so I can identify it.
