Can you not do that with earbuds?
What about a Simrig? I thought that recorded everything?
(as an aside, do I always have to type a Captcha to post/reply on this board or does that go away after a certain number of posts?)
Nope. Earbuds are -not- microphones, they are speakers. A simrig, if you wear one, can record all your sensory input, or you could just get a microphone to wear to record audio information.
Cyber-senses however record inside your head, rather to an external device. Maybe it's paranoid, but I like that level of security. They automatically come with recording units that allow you to keep your information on the devices themselves, and you can set them to only be downloadable via a datajack.
