I still don't see the problem... headphone comfort is and always will be a very personal thing. Most users buy online and can test their new headphones out for as many hours as they see fit. If they don't fit or are more uncomfortable than expected/wished for -- just return them. There are hundreds of competing models out there and chances are that one of them fits better.
I, for one, like my DT1350 very much. Thats unfortunately a model where the consensus is that it clamps quite hard and comfort is not optimal. Surprisingly I got somehow used to it and can now wear it for as long as I need (which is seldom more than 2h) without problems. Many returned them, most had an experience similar to mine.
This is in most cases not a problem of the manufacturer... the intended use for a specific model may put restrictions on the construction that are inverse to the design goal 'comfort'. Some manufacturers offer different kinds of pads to alleviate that problem a bit, but there is no 'right to comfort' so to say. No need to 'warn' 'potential customers' of fatal flaws, no demanding of changes. Express your personal view/opinion and vote with your wallet. If sending a product back give the manufacturer clear and positive feedback (i.e. not 'this is sh.t' but 'this could be done to make it better fit my expectations').
Its quite an unusual situation for the CEO engaging directly with the users of his products. To me this is the sign of someone being very confident with his product and, above all, very interested in making it even better. Being confident also means that a clear product vision exists. That in turn means that directions orthogonal to this vision will very likely be ignored -- a good product is not a do-all-for-everyone thing.
Offering additional pads that will preserve the sonic nature of the headphone is not an easy task. And its not the only one currently in the works I guess. It might still take some time... Even the M-100 got completed eventually ;-)
