I need a 20 or 25 foot headphone cable


I know this probably defies reasonable length soundwise but I need a 20 or 25 foot headphone cable for my Sennheiser HD 580's so I can listen in another room. any suggestions for how or where I might find such a beast?
I would like to be able to simply change from my short (stock) cable to this long one for those instances so connections on the headphone end are critical.

thanks in advance & cheers!

Do you want an extension or do you want a 20-25'er that goes in one piece from the driver units to the amp? If the former, they are available lots of places. For the latter, it would be available from many diff. aftermarket cable vendors, such as Cardas, Moon, Equinox, Clou, etc. For a description of the sonic and ergonomic diffs, try head-fi.org.
thanks Swamp...I guess I never thought about just getting an extension...that'll probably be easier & cheaper. take care.
Its called a headphone extension cable .Available everywhere.E Bay,BB,CC etc.Very common item.
