Reviewed finance status of self-funding and referenced several section websites with good sponsorship examples.

Speaker Shawn Olive presented study on headphones, with detailed listener comparisons. The study drew the conclusion that there was very weak correllation between On/Over-headphone type price and sound quality. There was somewhat better correlation between price and sound quality with in-ear headphones. Also reviewed correllations between Dr. Olive’s findings and several other prominent headphone review resources.
