The only headphone cords I've ever used have had standard 1/4" jacks.
I know my HD800S's came with a 'mini XLR' cable for 'balanced' use into an amp that has that kind of input (two small plugs, one for each channel).
The V280 has a single 4-pin XLR plug. I know people generally say 'balanced is quite a bit better' but is there any benefit at all to switching from a 1/4" plug to a 4 pin XLR?
I always thought 'balanced = XLR' but I guess I'm not sure about if that...
