ELI5: Is our real voice the one we hear in our head or the one we hear in recordings?

I've heard that the voice we hear inside our head is actually one octave lower than our real one but when I'm playing online with a mic with friends that I know in real life they always sound a bit different than they do in person and they say the same thing about me, so which projection of our voice is the real one?

Recordings. 

When you're playing online, you're not getting a good, high fidelity recording.

However, if a good mic picked up your voice and filtered and played it back well, that'd be your real voice. It sounds different to you because it travels through all the fleshy tissue and bone in your head before hitting your ears.
