Do not use Monoprice cable! I did a re-cable with one of their "Premier" cable which is suppose to be their best cable and do not like the how they sound. These cable muddy up the details compare to the stock cables. The cables you are looking at are very thick and stiff. The Premier version are thick but not as stiff. I had to strip mine and braided the cable. Re-cabling with this cable was not worth it because it sounded worst then stock.
Do not buy the 1/4 to 1/8 adapter from them to use with the stock T50RP cable. Those are pure crap and the sound will cut-off like crazy because it fits very loose. Get the Sennheiser' 1/4 to 1/8 ($~6) if you don't want to pay for Grados.
If you are going to do a re-cable, make sure that it will improve or at least be equal to the stock cable. I'm in the process of redoing my cable again once I get my silver plated cables gets here.
Dale Audio has the best price on Neutrik 3.5mm TRS Plug and is free shipping. Buy some heat shrink while you are at it too since it is also pretty cheap. For cable sleeving just get some 550 lb paracord color of your choice. Do not get Techflex Pet-Flexo because it is prone to microphonic. If you just want a cable with 3.5mm, just get the V-Moda cable that LFF or somebody mention. It is more simple and cheaper.
Cheap but decent route:
Navships 26gauge silver plated copper 25' $7 Navship ebay /or (conare or mogami cable, the cable itself isn't too expensive but the shipping is). I went with the Silver Plated Copper.
Neutrik 3.5mm $1.35 (might as well order a couple more to make some mini to mini with all the extra cable)
Paracord 550lb 50' $5 amazon or Braided Nylon Sleeve $7 from furryletters ebay
Just letting you know so you don't make the same mistakes as I.
