Need some wireless headphone learnin'

[bejeeber]

I need to supply a performer with wireless headphones for recording and overdubbing.

That may be against orthodoxy, just plain wrong, blah blah, etc., but what I'd like to know is whether there's a nice light'n comfy pair out there somewhere that aren't going to introduce some processing delay.

One model that just came up for consideration is the Sennheiser RS-140.

Thanks.

Meantime I've learned that the RS-140 are FM cans and introduce no delay, so I'll be making sure to go that analog radio route.

If anyone has other suggestions for headphone models in this category, I'd arpeggiate it.
