Any help would be appreciated. I am still looking for quality 2.5mm TRS Plug. I am also looking for right angle 2.5MM as well if you have any suggestions. Thanks for your help!

Here is a few don't have a idea on the quality of them just a google search. Most people here use TS or TRRS 2.5 mm connectors.

Thanks for the links. I have been looking all of these up as well but looking for a quality one! Thanks again.
Do you have to have TRS?

Hi folks, got some qpad qh90s, the sound only works in one ear. The ear on the other side of cable entry.

I wanna have a whirl at recabling them.

I've found the website canford.co.uk which had some cable mentioned earlier in the thread. (Belden 1508a)

Now I quite like the look of mdpc-x sleeving also.

Would I strip the wires from the belden cable (out of the PVC part) and then just run them through the mdpc-x sleeve or do I leave them in the PVC part and run it all through?

If stripping out do I have to braid them first?

Stripping a multi-conductor cable is mostly about looks than performance (as long as the cable is short, say about 6 feet or under 2 meters). Depending on what you want them to look like as you can individually sheath then braid or braid then sheath the braid. I like the look of individual sheath-then-braid.
 
Not sure about the wiring of those headphones. The Belden has 2 insulated conductors, an unsheathed ground, and a shield with PVC insulation. If you headphones already use a 3-wire cable then this cable might be suitable for single-ended wiring (i.e. TRS plugs), but using an unsheathed ground as the common "negative" seems weird. If you strip it, you will probably need to strip double the length of cable so that you can use an insulated wire for the common ground.
 
If your original cable has 4 conductors, then the I think the 1508A is not a suitable cable unless you are stripping it for the insulated conductors.

Thankyou for your reply. I think if I understand correctly then a quad cable.may be a better option then?

It will be wired with yes so 3 cables.

Could I use 2 runs of this for it?

If you're recabling the headphones all the way anyway, it would likely be easier to use quad cable. Stripping all of it is up to you (you certainly don't have to, especially with single entry), but you will need to strip enough to go around the headband from one cup to the other (provided you want to replace that bit of wiring too).

2 leads to the ground, one to the right and one to the left. I would pick something like Mogami 2799 if you can find it. It's cheap and the conductors inside the sheath are 4 separate colors. Makes keeping the Ground/Left/Right wiring separate easy.

Be very careful soldering to the left speaker (and the right one too, for that matter). It's really easy to leave the heat on too long and damage the driver or the solder tabs.

Looking for recommendations for high density nylon sleeping. There are so many out there. This is for outdoor use. Have looked at Mod DIY which looks quality as well as Techflex and Kobra! What are your thoughts! Would be 3mm or 1/8".

I'm looking to make a new cable for my newly acquired AKG Q701s as I'm not to fond of the stock green cables that they come with. I have found the connectors that I'm going to use already, the only problem I've run into is that I'm not sure which cable I should buy. The connection is a 1/4" TRS connector to a mini XLR if that helps. I'm pretty new to this as this would be the first cable that I've ever made so any help would be greatly appreciated.

You can buy any cable you like. I like Mogami (either 2799 or 2893, the connectors are the same size) because of the price.

I believe that the Q701s use a 3 pin mini-xlr, like a lot of AKG headphones, and any 1/4" TRS will do.

Please note, though, that AKG likes to wire their XLRs backward:

http://www.head-fi.org/t/55290/wiring-help-for-diy-akg-k271-headphone-cable

Normally, a mini-xlr is wired

Pin 1 - Ground
Pin 2 - Tip/Left
Pin 3 - Ring/Right

AKG like to reverse pins 2 and 3. A multimeter will help sort that out and make sure that you wire it correctly.

If you're looking for a list:

http://www.redco.com/Mogami-W2799.html
http://www.redco.com/Redco-TA3FB.html
http://www.redco.com/Amphenol-ACPS-GB-AU.html

Those 3 together will make a fine cable, though you might want some sleeving for the Mogami. I think 550 Paracord with the middle bits removed will fit over that mogami, though you may have to remove the outer jacket (but not untwist) first.

this is a very fine silver plated copper 28-30 awg
cheap stuff from navships, wicked flexible
amphenol and rean connectors, i like the rean mini xlr for its strain relief
braided and sleeved in 550 paracord
 
i would suggest mogami 2799, best bang for buck, and flexibility, durability
