Hi, I want a 3.5mm extender for my headphones that will not loose quality with audiophile headphones, and be 5-10 feet long.
I would appreciate some suggestions.
Just about any properly shielded cable will do.
Unless we are talking about concert use stuff, unbalanced and shielded should be fine.
There are quite a few people here that'll make a custom cable for you for a relatively cheap price, although most of your average cable in electronics store should work.
You would lose quality over a LONG distance unless you go balanced, but headphone cables don't go to those extreme lengths.
