many thanks. what is multiple of information gained - i would need, like, 3x to match 802 capacity right now, looking at aura comminication's headphone set. I'm hoping my office'll go for them. I think I can 'roll my own' directional/varied range thingies. Hell, dunno what they're called yet. Rarely seems to matter. They use a chip. 
Asking their rep why they don't use the magnetic field to power headphones also - why bother with batteries??? Like idea of no physical plug for puter, dual purpose out/inport 'n power recharger. D. Makes sealing in block of acrylic viable. 
(Polite request - please only include key original tracts that one is referring too - some of us have really slow modems. Thanks.)
