RE: Cheers mate, but.... Sorry, thought I might be able to post before your appointment! It's certainly a strange experience. I was trying to work out how the headphones work without magnets or metal parts.
It's a very odd experience, it's like you're in a sub that's been torpedoed or something. All the creaking, banging and alarm type noises going off. That's from my experience as a submarine commander and definitely not television or films.
They work on air pressure Like the old headphones you used to get on long haul flights. Sound is, after all, air pressure waves, so I presume that. Anyway as you can see my fillings are still intact
