I live in Vallejo near Infineon raceway and last week I got to take a racecar driving lesson. It was so cool. My top speed was 114 (don't poke fun, it was my one and only lesson, they don't let you get too fast). One of the things I noticed in the car was the quality of the headsets they use are amazing – those cars are LOUD and these cancel out pretty much all of the noise. I had a super-cool instructor that piped music through when there was nothing to say to me, and I noticed that the sound quality and bass response were pretty damn good. I looked at the brand, they are OTTO headphones, does anyone know if they sell these and where?
