The Shure KSM8 design claims are made clear on their website. I check them out and err check them!

Shure's KSM8 Webpage is interesting and detailed and many claims are made for the new design: www.shure.com/en-US/support/find-an-answer/ksm8-overview-benefits-and-technical-details 'Overview, Benefits, and Technical Details' are covered and I compare this classy 2016 microphone to the 1962 design Beyerdynamic M88 (80's version) to see how much (if at all) things have improved.
