Your last line sums it up in the most meaningful and truthful way, and I have direct proof of this: I had invited two friends, husband and wife, for tea. He is a German music producer and owns his own studio, and the wife shares the passion for music. They're no spring chickens, and neither am I, so our memories in terms of music go way back. I offered them to try on my Valkyria, first to the guy. When his wife's turn came, I knew from our previous conversation that she loves Genesis, as I do, and she selected a live concert, the Lamb Lies Down On Broadway Tour of 1974. A few minutes, and tears started flowing down her cheeks. When I asked her, after she finished listening to the songs, she said: "You know, I was there in person, in 1974. As soon as I closed my eyes, I was transported back in time by the music, and it felt as I was there physically, again" Like you wrote "I'm there, it is real".
P.S.: You can easily adjust the clamp force of the headband by twisting it in a certain way. If you email Andrea at Spirit he will send you a short video that explains how, It's really super simple.
