Thanks for the comments. Clamping tension is being re calibrated on the Pros. If you still have them, I'd be happy to swap them put for you

I am a Director Product Development at. Monster. While Mr. "K" has been privy to engineering documents in the past I can assure you that he was not part of the team that designed and engineered the DNA headphones.

Nice try. The drivers are not the same. Unqualified statements like these turn forums for useful information into "village people" rant sites. Please try to make informed posts and not to turn these threads into campaigns against large manufacturers like Monster.
