What about wireless'? I've looked' but I never got around to checking any out.
There's a truism in the live sound side of things:
"You can spend two to three thousand dollars on a wireless system that's almost--but not quite--as good as a ten dollar piece of cable."
Even the best wireless system, as good as it is, won't sound quite as good as a direct cable--mainly down to the companding used in most FM systems.
Beyond that, don't forget you'll need to change batteries every 8 hours or so--and there's some kind of fundamental law of physics that says wireless batteries always go at the least convenient time. (Usually at 2AM on a rainy Sunday morning when the only place you can get more is the 24 hour gas station 10 miles from home--you know, the one that charges twice the going rate for batteries!)
Finally, don't forget that most guitar wireless systems still involve a short piece of cable to a pack that you clip to your belt or guitar strap--so, while better than a long cable, still has potential to tangle with a headphone cable!
