Title: Giving false info.
Review: If you look at the Tech. Data on the AV-2000, it says it puts out 33mm, but that would be false since some of the best headphones out there put out that much, and I mean studio stuff. So I looked up these headphones on another site, and found out that they are only 13mm, and a ... cheaper. I can't tell you where, but you might want to look before you shop. This does not make these bad headphones though. I might just buy them.
