Seems like a great way to keep the ear hairs trimmed.

High voltages and high frequencies right next to your head? What could possibly go wrong?

Just saw these bad boys in passing and if the headphones above don't cut off your circulation, these will http://tablets.engadget.com/photos/nox-audio-admiral-touch-hands-on/

The headphones themselves are really good quality and well made.

Let me know if this helps.

Ha ha. Well electrostatic headphones like Stax Lamdba models, and Omerga models too like the SR-007 or $5,000 SR-009 have 580 volt DC bias "right next to your ear" and I'm not aware that anyone's ever gotten a shock etc from these.

My concern would be HEAT. These plasma cells produce heat. Not burn-your-ears heat, but I would think you'd be sweating your brains out after a while. My ears get hot from regular over-the-ear headphones, and that's just from body heat.

Talking Not much of a heating problem.

The Plasmasonic headphone use the Corona wind effect, not plasma. It's like moving air with an audio modulated high voltage without using diaphragm like electrostatic headphone. The only moving parts are the air molecules, so it is believed to be the ultimate audio driver, but in fact it suffer much distortions and it failed as a commercial product.
So this being said, I am still very curious to ear for myself such a device, and it was once a project that i was eager to actually build.
Try to do reverse engineering from photos and small conceptual schematic.
But i decided to put my efforts to build an electrostatic headphone instead.
That actually works very very well, thanks to Chinsettawong for the inspiration.
Hope it helps you.
