Just gently pull off the earpads and you will see the 4 screws that you need to remove.  They are covered with tape.

Gently does not seem to work. Which direction should I pull and where should I grip? Should I use screwdriver or sth?

Ok, I have figured out. You just pull the leather slightly rotating, and it just comes off smily_headphones1.gif

Do anything fun with them?

No. I just discovered that these cans sound better when on ears, instead over. The bass is bigger, and isolation is better. Also highs are less harsh, and sub-bass is more visible. In quiet room, these cans sound really amazing when worn on ears. I have also noticed that on ears they actually cause less harm. To better the comfort, besides stretching the h-band you can also stretch earpads, and also push them hard to your head few times. It actually makes earpads seal better with your ears, and also they will fit better shape of your ears.

I was thinking about removing original filling, and replace it with memory foam. I need to order foam first:)

I am right on the border of on and around ear with the Momentums.  Most of the time I have more comfort around the ear.  I might experiment with different bending schemes to see if on ear will work for me.

 

BTW, a great source for memory foam is memory foam contour pillows.  I got one from that I have torn apart from Walmart for $15 that has enough memory foam for dozens and dozens of earpads.  If you don't have a Walmart in Dublin, IKEA also has a similar pillow for only $15.  I haven't torn that one apart yet since I actually sleep on it :)

Obviously, a fantastic finished product, as always. Couple of questions if you don't mind.

 

1. I'm assuming you're using paracord? Since you have a lot of experience with it, is it all more or less the same or should I be looking for a specific supplier?

 

2. For the life of me, I cannot get a 4 lead braid that looks even and uniform like yours. Do you have any tips/tricks that might help keep a uniform braid? Also, is there a guide you use? I cannot follow that chimera labs one at all. 

 

thanks

Thanks for the kind words.  

 

1.  Yes, this is Type 1 Microparacord.  I get it cut from a larger spool, so I actually don't know who manufactures the actual cord.  I get it from either 5starEDC (http://stores.ebay.com/Five-Star-EDC) on ebay or SupplyCaptain (http://www.supplycaptain.com/index.cfm?fuseaction=category.display&category_ID=21)  depending on what color I want.  

 

2.  I typically solder the wires to an end connector first and then anchor that connector in a vise that I have mounted to my desk.  I keep the cable in light tension as I slowly move back, which helps keep the braid pretty consistent.  Every few inches, while still holding it in tension, rub/push in several directions to also help keep it consistent.  As for the guide, I simply say to myself as I braid, "Over two, over one, under two, under one."  Basically take the leftmost wire and and lay it over the next two to the right.  Take the right most wire and lay it over the next one to the left (the original leftmost wire).  Then take the new leftmost wire and pull it under the next two to the right, and then take the rightmost wire and pull it under the next one to the left. Does that make sense?

1. Awesome thanks! Figure I'll just find the colors I like then! 

 

2. Surprisingly your text without pictures has painted a clearer picture than most the guides I've seen. Thanks so much. I think the trick with an anchor will alleviate some of the headache from not having enough tension in the lines. 

 

If you ever start selling prebraided stuff I'll be first in line biggrin.gif Always top notch work.

Beautiful job, I always admire people with craftsmanship.

 

...ever thinking of doing it for others... you know like on the side?

Thank you.  I think about it all the time :)  But, unfortunately, my free time is virtually non existent - what cables and mods I do now are just for me to blow off steam.

Only problem is that there is a TRS 2.5mm jack on only one side, so while making a new cable is a breeze, it wouldn't be balanced.  Since I didn't want to risk marring the looks of the Momentums by drilling to each driver, I decided to see what I could do to the jack.  I wasn't thinking tutorial, so I only have a couple pictures, but the great news is that the 2.5mm jack is mounted to a PCB that is easily unscrewed from the driver and can be easily de-soldered if you have a solder pump.  Once the 2.5mm jack is removed, you have 4 very convenient places to solder the new cable to, including separate grounds (they were joined inside the jack, not on the PCB).  All in all, ended up being easier than I thought it was going to be due to the extremely convenient PCB.

 

Here is a picture of the board with the 2.5mm jack already removed:

 

 

Here is the back of the board after soldering wires to it:

 

 

Ready to solder the drivers back onto the board (that is hotglue on the board used for strain relief while braiding the cable):

 

 

Finished with a mini-XLR:

 

 

Very nicely done! What kind of wire and cable sheath did you use? And where did you source them?

Thanks!

 

The wire is finely stranded 26AWG UPOCC copper in thin, clear teflon.  I got it as a sample from a friend who was experimenting with different wires.  I don't know if it can be purchased from the original source.

 

The sheath is my calling card - Type I micro-paracord.  I either get it from 5starEDC on ebay or supplycaptain.com depending on the color selection at the time.  I'm pretty sure the color I used for this cable is Tan from 5starEDC.

Many thanks. I'm gonna order some sheath. I don't know where to get UPOCC wire. Will have to research.

I get most of my wire from Doublehelixcables. Toxic Cables and Plussounds are two other vendors to look at.
