Conway's History of the Ship: The Heyday Of Sail.
Oh, and an update: The headphones are spectacular! The bass response is all I could have asked for. In fact it was way too much at first. After some checking I figured out that my old headset was so crappy that I had the equalizer adjusted for the absolute maximum bass, plus the bass booster turned on and cranked all the way up. After some adjusting the sound is just about perfect. Even the bass viols and voices in a lot of the classical music I listen to stand out now. The microphone works perfectly.
The only downside are the LED lights. I don't need or want gimmicks in my stuff. It's annoying at night and can't be turned off. Still, for twenty-five bucks this is an amazing headset.
