Audio Extension Cables

[Heywardo]

I am a bit new to this whole head-fi thing and at the moment I'm in a slight predicament. 

 The chair from which I watch television in is just out of reach of my headphones. I need an extension cable preferably 2 meters in length and terminating at a 1/4 inch audio jack. So I was wondering if there is any major difference in sound quality from a cheaper cable to an expensive one, I don't want to be spending heaps of money so if someone could recommend me a cable that would be fantastic. If the loss of sound quality is minimal I may just buy a cheapy of eBay.
Just for clarification I'm using Hifiman He400's from the Schiit magni.
