You sure about that? Normally Red == Right

@pkay
You giving @plakat a 'like' on his reply to my post above worries me that you don't know which wires are which for the L & R channels. Before you do any soldering--do you know which are which? I know 100% being I've terminated every single Grado I own--or have owned to Neutrik 4-Pin XLR--with the exception of my 325is.

Grado sr 325 X : Where can I find padding for the headband that I find uncomfortable?

You can try double-sided tape and replacement headband pad for the HD650, HD660, HD6XX.

That is correct. I always use my Grado schema whenever I need to solder a Grado hp!

Some more info here (but it's about the Ps2000e 12 conductor cable): I
changed the cable on mine from 1/4 to 4pin XLR. I remember a few tips for you.
1: all Grado�s have 4, 8 or 12 wires running all the way between driver and connector.
2: all Grado wires are colour coded, there are 3 colours.
3: the easy way to determine left and right wires is to use an ohm meter, listening for a scratching sound to emit form the driver when rubbing the contact. Do it 1 wire at a time.
4: all Grado�s use blue wires for - on both sides, white for + on right side, red for + on left side.
5: the jack tip is the L+, the ring is R+ and the base is L and R -.


Pin 1 3 reds(L+), pin 2 left 2 blues(L-), pin 3 whites(R+) and pin 4 2 blues(R-). You just need to figure out which blue wires is for the left and right.

I see you're from Belgium--I very recently purchased my NOS BNIB PS1000 from Technology Factory which is an online store located in Antwerp, BE. Great communication with very fast shipping to the US>

But wi don't think it matters that much for the blue wires left or right.

I have never heard of that company. I will search them on Google thanks !

Correct--you need to find ~32Ohms between the + & - wires.

 

[joseph69]

Yes--it does matter.
As I mentioned in the above post, you need to find ~32Ohms resistance between the + & -.
2 specific blue wires (32Ohms) out of the 4 go to the R channel and the other 2 blue wires (32Ohms) go to the L channel.

@alexdemaet
Of course my post above is regarding the 8-conductor cable.

Yea I got the color code directly from Grado and had a professional do it. Actually it was several months ago

 

[pkay]

This is true. Breaks the rule in Grado sorta way.. lol

My comment can be misleading though.
Red==Left in Grado world!!

Interesting… I don’t plan to reterminate any one of my Grados, but still good to know where to start.
As @joseph69 mentioned one needs to check which blue wire belongs where anyway, which would reveal that association Red==Left as well

Red==Left in Grado world!!

That's how it is in the UK as well.
