Amongst the deafening noise in the main expo hall of PAX 2011, Sennheiser had a small booth to show off their line of non-isolating, non-noise-cancelling headphones. I like Sennheiser headphones but this seems poorly thought out.
Perhaps more remarkable is the maingear mouse pad which is the worst mouse pad I have ever physically contacted. The mouse actually sticks to the pad. They have somehow invented a surface that sticks to teflon and made a mouse pad out of it.
