Hi Everyone, A video came up on my YouTube feed talking about this book on Sony personal audio products. https://www.2old4gaming.com/store/sonybook2 If you go back to their main page they also have a general Sony products book, as well as electronic versions of them both available, and there is a kickstarter for a 3rd book. Please note that I am not affiliated with them in any way, but I did a quick search on the forums here and didn't find this book mentioned. I am sure there will be a few people interested as I certainly am!
