    Ohh, thank you man!

    Sorry I got busy and could not answer. By jacket I meant a pvc or rubberized coating that surrounds a group of wires like star quad cable. In audio those wires are often twisted pair. You do not have much loss with it, start with four feet two inches and build a four foot cable.

    Interesting project to do at free time

    20-30% is quite high, IMHO. even when I use the braiding disk for a super tight braid, I only lose 10%-15%. When I hand braid with a lose braid, I lose very little length. Still, it's better to have too much wire than too little.

    I have had as many as five people learn to braid and oftentimes they end up with the wires at different lengths so they have to be trimmed. For me wire is cheap compared to the time it takes to braid so I allow for a little extra but then we do this for a living and if a customer asks for 4.5 feet, I cannot send them four feet. When you are building a cable for your own use and you are the responsible party, what ever result you get you can live with if you like. I go with at least 20% extra wire as a rule of thumb.

    If we do have a few inches of braided wire left and if it is more expensive wire such as Occ copper, we normally build short 3.5 mm interconnects for say going from a phone to a portable amp such as an OPPO HA-2. I am always looking around for those and when you have multiple headphones and cases they are easily misplaced.

    I received the 1505F and have a question. Do I have to solder all the shield? Can I trim some of it to make it thin?
  7. Paladin79
    you can most certainly trim some. Generally what I do is make one slice in it and then twist the bundle together. You can thin out the bundle and shorten it as needed. About the only connectors where I might leave the shield intact are some mono quarter inch connectors that have a very wide sleeve portion that will accept more braid. If done correctly you will not run the risk of any of the braid getting close to the center conductor on the cable. I tend to solder most any braid that might come loose to cause a short. Once it has cooled run your fingers over it to make sure no loose strands can move toward the other connection.

    I am considering making a 2m and a 4m cable for the AKG K812.

    Can anyone confirm the pin config for the Lemo 3-pin plug and suggest a suitable cable to use please?

    Guys, I have JH16v2 and considering to do diy cable to avoid that moon audio which is a big mistake. Can please anyone provide a pinout for their 4-pin connector with or without cable attenuator (bass adjuster).

    Thank you all

    Do not know but I would not give up the bass adjustment as I found it too much fun. Heard it on the Layla's and Lola's and I did like it not for sure on the ones you have but most (not all ) cables for iems are the most outward are positive so you will have to have a multimeter to test that. Are you talking about a 2.5mm balanced cable or something else?

    I would like to create a basic 3.5mm cable, but this would be my first go at it. Would I be able to use 3 strands of cheap 16g copper wire? How would it sound compared to more expensive options? Would 16g be too thick to solder and use properly?
  12. Paladin79
    I would not use anything that large. It will be bulky and you would have a hard time using it with some 3.5 mm connectors. If you really, really want to do this, Canare makes a connector you could probably use all right. It is not too thick to solder but you have to consider the lugs or barrel you are trying to solder to. The best connection IMHO is wire looped through a solder lug and then solder applied. I was taught to never rely on the solder itself to hold the connection and you would most likely be tacking that wire to the side of the lugs. Go for 24 awg, or even 22 but save 16 for speaker wire. Sound quality might be all right.

    Cool thank you for the reply
  14. Paladin79
    You are most welcome. What length cable are you looking to build? I may be able to send some cable your way no charge that would be more suitable. It was the Canare F12 connector that has a large cable opening by the way.

    that would be aweosme! I'm aiming for around 3-4 feet, as it would be used as a daily carry or with a dac very close to me
