I actually did this fix in the past, but im not so sure: which wire goes where?
Obviously my cable got a ground wire + colored wire for each driver, why are there 4 connections on the driver itself? is the red marker on the magnet an indication for something?

Thanks for the help and sorry about the nooby questions!

Normally the red dot is the + side. But that is not the same for all manufacturers. I would ask the manufacturer or seller of the drivers.

What is "+ side" ? The ground wire or the colored one?

Coloured should be the + signal.

Coloured should be the + signal.

hmmm seller wasnt helpful. I think ground under the red marking sounds slightly better, really hard to tell.

Impossible to know. You'll have to wire them up and then put through a polarity test. I purchased one on the phone app store for a couple of bucks, it uses the speaker and mic and lets you know if the speaker is in phase or not.

ok so i already lost my mind lol.
Tested with 2 cables, did polarity tests here:

Everything they say is noticeable with my PC speakers, but with these drivers "In Phase" and "Out of Phase" samples sound the same no matter if i connect the "+" on the most right "pad" or the most left one. Wish i knew what i'm doing wrong...

I tried that one too, got nowhere, Try Speaker Pop in your phone's app store, I've verified it works with headphone drivers.

not on Android tho...

JBL brasil seems to have a similar app, i'll check it tomorrow.

Thank you for your help so far!

Hi Viber, coloured dot is signal (+) side, non-coloured dot is ground side. Even if this particular headphone is 'the other way' it doesn't matter, so long as you do the same on both drivers, then they'll both be in phase. Solder the wires to the outer tabs only, the inner tabs are for the coil wire, you can see the inner tab is connected to it's respective outer tab in the circuit board copper, you can see a lighter colour in the circuit board between the inner and outer tabs indicating copper connection. The coil wire is soldered to the inner tabs, it is best not to solder to the same tabs since excess heat from the iron can dislodge the coil wires, and that will likely become unrepairable. That's why the wires go to separate tabs, to provide some thermal isolation for the coil wires.

You sound like you know what you're talking about and this is line with stuff I've read in the past. Thank You!

Anyone has something important to add ?
