i've always been a bit of an audiophile. I've been interested in electronics since I was 7 or 8. My dad found an old electronic project lab from Radio Shack similar to this one here from Amazon. I built everything in the project book ranging from a light-sensitive alarm clock to a complex circuit that could simulate random dice rolls. I even built a small AM transmitter that could broadcast my voice 3 feet.
So loving electronics and audio, I was determined to find out as much as I could about it. I even tried to build my own audio mixer, but the ol' project lab didn't have enough components to do much more than make a karaoke machine... :( But it had an audio output and the mic had an input level, so to me it was pretty cool at the time!
Then a friend of my parents gifted me his old encyclopedia of electronics and in it was a blurb about Pseudo-Stereophony or Pseudostereophonics, the study of which is apparently called Psychoacoustics. According to the encyclopedia, it was only a concept that would one day find a practical application, but at the time of the writing (1980's?), there wasn't much going on with it and it was only a concept. About two paragraphs, but I said it was possible to do with any audio source, on the fly.
Here's an article explaining a bit more for the technically oriented who care about it.
EDIT:
For what it's worth, in order to produce a sound as if it were coming from in front of the listener, one would require to produce a sound and then a fraction of a second later, an echo that is out of phase since the echoing sound would be out of phase of the original sound.
To produce a sound as if it were coming from the rear of the listener (make a raspberry noise!), one would require to produce a sound and two echos. The first sound would be quieter due to the shape of the ear, sound cannot easily enter the ear canal from the rear. Then the first echo, out of phase similar to a source in front of the listener, since that sound shit likes to bounce. Then depending on the environment, another much quieter echo would then be played (again out of phase...damn echos) to simulate the original sound bouncing off any objects in front of the listener. I would say that any earphones that support this technology would need two audio drivers in the earpiece. A high-quality one for the original sound source and another, fine-tuned driver that would produce sound on a spectrum consistent with the spectrum of audio commonly carried in by echoing sound waves.
God, I'm a nerd.
I had one of those Elenco 300 in 1 project kits as a kid and they are a wonderful way to learn the basics
This?
Honestly these things are pretty good. Not for the hardware, but for the manual that comes with it.
Work through every single project, and for each one, once you've built it, change a detail. Predict what effect your change will make before making it, that's what'll really promotes learning and reasoning.
This thread a few days ago might be interesting too.
This one looks more like the one my brother had. Sad face for the price :( I want it, but cant really justify the cash.

This is how I got interested in electrical engineering.
The problem was I only realized years later that a lot of EE is programming and not actual circuits and circuit design. I love circuits and stuff but hate programming so take that for what it's worth.
Switched to chemical engineering sophomore year of college and never looked back.
Learning the fundamentals of electronics usually involves lab equipment like oscilloscopes, meters, signal generators, etc. For this I'd take an electronics lab course for some hands-on learning and experience with the various electronics test equipment.
Basic info about components is in places like the AskElectronics Wiki and the Big Clive videos.
An Electronic Project Lab kit is basically a lot of simple projects and a good learning tool to start out with.
