If anyone is wondering if they should purchase a red or black K7XX, stop wondering and join the color drop of your choice. They are a steal at $199! Below are a couple cable choices if you want to keep the 10 foot long stock cable in the box. I own both of these cables below and they look/work/sound fantastic!

BJorn_LuLszicThe audio sounds the same from my listening tests but those cables give you shorter length options compared to the really long stock cable.
BJorn_LuLszicyes. it sounds like 400 headset. not 200. but seriously. read some electrophysics. cables won't make difference in 0-40khz range. even the most horrible ones
