I would look at some of the feedback they're received over on Headroom.
MANY people are dissapointed with the bad quality and TERRIBLE customer service and several have gone back to the stock pads.
Most people realize that Denon actually has the BEST design and any change to that design is NOT an improvement.
It's like J-Money has monkeys doing all the work.
I would NEVER deal with that company.
I'd make my own pads before paying someone $100 for a pair of leather doughnuts.....I can get 2 chocolate frosted for $1.20 or $6/dozen.
The Denon cans are my next purchase and I plan on keeping the stock pads.
Buy another pair of headphones or another portable amp for the money....seriously.
