My contention all along has been that the issue isn't as widespread as some suggest. I never said it was a figment of anyone's imagination.

Consider this: My job is fixing phones, software and hardware. All day long. 5 days a week. Sometimes a customer will ask me if their problem is a common one... I reply that I can't really tell, because I only see people if they have a problem. All I know, is most people must like their phone enough (and $ investment) to try and get it fixed. People only complain if they have a problem, but we really cannot gauge how many people are happily enjoying their product and never have to come for repairs.
Head-Fi is a special collection of enthusiasts, and this thread in particular is like THE high-visibility place for M-100 feedback. I'm actually impressed with the number of content consumers in this thread — those started out as people who were already regular visitors to the site, and I'd suspect that their (our, cuz I fit the description and am pleased with my M-100, even if I had to wait a year to afford it) continued enjoyment and support for the product encourages others, who stumble on this thread before purchase, to give their own opinion on the product when they get it.
Personally, I have a lot of fun listening to these headphones. They're the best closed headphones I've ever heard, and they make sense to me because I wouldn't use large closed headphones at home (quiet enough here, so I've never been tempted to buy Denon's high end closed headphones). They're perfect out of the box IMO for listening during a mass-transit commute, during a break at work, or to just listen to a few songs without disturbing someone nearby. I agree that with longer listening sessions, say when you start going over an hour, they cause discomfort and I need to take a break. I think that for most people, most of the time they use it, the M-100 is a great/superior headphone. Now, if I wanted to listen longer without repositioning and taking breaks, I might consider new XL pads, but IMO the closed headphone category will always be a comfort concession due to trapped heat and the sealed leather/pleather pads. If you want to listen for hours at a time, the simple fact is that open-backed, large, circumaural headphones OR speakers are your best bet. Right now I find the M-100
more comfortable and sound
better during that first stretch if I position mine so that it lightly pins back the back edge of my ear against my head, as opposed to tucking my ear in under the pad.
I have more opportunities to wear my M-100, even though I have longer single sessions with my AKG K712 Pros.
